Rythmik F12SE Direct Servo Subwoofer Review. **READ THE PINNED COMMENT**

[@NemoPropaganda]

***CORRECTIONS & UPDATES*** -When I said I wouldn't use it for theater I think a lot of people misunderstood me as saying that it's not capable. This is just as capable as any sealed 12" and will best most of them in a theater environment. What I was saying is most people who build theaters generally use larger ported subwoofers like Rythmiks own FVX12 (which I also love). Again just to be clear this will be a dominant competitor in a theater environment. -Another note on dynamics, a lot of you guys misunderstood me and maybe that's my fault. This subwoofer is plenty dynamic, it just integrates extremely well and for my personal taste I like exaggerated bass that is less accurate and more exciting but that is just my personal taste guys. Do not take this off your list just because it doesn't have the exaggerated characteristics I like as you may prefer it's more natural and accurate bass response. This is an outstanding performer and years later I still own this, if you're like me and prefer a slight exaggeration in the low end go for the FVX12 (I own that too). - I referred to the L22 as the L12 at one point during the comparison, should be obvious which part.

[@NemoPropaganda]

@Yama Fanboy yeee lol

[@danemoreno88]

I’m choosing a pair of these to go with my svs ultra towers hopefully they fair better than the dual L12’s i had my system Is even 50/50 music & home theater

[@NemoPropaganda]

@@danemoreno88 hey bro, just curious what did you not like about the L12? The F12 definitely has more fidelity, SPL, and extension in it and holds it's composure much better at the limit but if your room is big or you're looking for incredibly strong bass I suggest you go for a pair of the FVX12 instead which has A LOT more output and plays just as clean. If that's not an option the sealed E/F15 will also be a great option.

[@danemoreno88]

@@NemoPropaganda I just felt that they couldn’t keep up with the 2 8 inch woofers per tower playing in my left and right I felt that I couldn’t really hear it unless I turned it up on the gain on the subs like I said I really like listening to music so I prefer sealed subs but I also use it for home theater TV games etc and I’d like it to match my piano gloss black svs ultra and I feel the svs offerings are too expensive for what you get and don’t sound as good as rythmik

[@NemoPropaganda]

@@danemoreno88 okay cool cool, so yeah the F12SE will definitely be an upgrade, if you can swing it the E15HP2 also comes in gloss black and that will give you a huge upgrade in the theater side of things while still being a big upgrade for music compared to the L12. Just to be clear the F12 is a clear upgrade from the L12 but since they're the same size I'm just worried it won't be that BIG upgrade most people look for hence the suggestion of jumping up to E15HP2, I have one here now and will be reviewing it soon.

Great review. I'm learning subwoofers are the most complicated thing in a system. At least for me they are. I've spent more time trying to figure these things out then I thought I would. They are also something you don't see many people reviewing. So much appreciated.

[@NemoPropaganda]

You and me both my dude. It's also somewhat our fault as we're not using any softward for integration. The home theater guys use things like Dirac or other room correction easily integrate a subwoofer but stereo amps don't have features like that.

i've owned subs from Hsu Research, Energy, SVS, and Power Sound Audio. SVS and PSA definitely make great subwoofers, but none of the above can compete with Rythmik's sound. my one regret is that i waited a dozen years between first wanting an F12, and finally owning a pair. the F12 doesn't even sound like a subwoofer. it sounds like i have a pair of truly full-range speakers

[@ehall8929]

Very nice review and explanation of the performance characteristics of this sub. I actually own the non SE version of this sub (F12 in the Matte Black finish) I have used it for over 3 years now in a smallish room (12 and 1/2 feet by 17 feet), with a pair of Ascend Acoustics tower speakers, and it performs very well. The bass with music is tight, accurate and Impactful. When I go back and forth with using the Pure Direct mode on my receiver (No sub output) and the other modes, Straight or Dolby surround the difference is clearly heard. One thing I wanted to point out is that for movies is not going to shake the house, there are some settings on the back you can adjust that makes movies sound great as well. The first thing is, change the damping from "high" to "Low" and turn the rumble filter off, for more output and it does just fine with movies too. But if you really want to rock the house for movies you probably want dual F12s or get a bigger more powerful sub. But again, great review. And I love my F12!

[@NemoPropaganda]

oh yeah, low damping is ideal for theater use, even good for some music genres. I didn't want to get into the settings too much in the video because that could have easily added another 10-15 minutes lol.

Hi Mike, I'm happy to be of service! What speakers are you using?

[@firebladeclements]

Magnapan lrs's and b&w dm3000's. I left a question on one of your other videos regarding speed to match the lrs's. May have to stick with rel! Cheers!

[@NemoPropaganda]

@@firebladeclements Ah! I see, I would try whichever brand you feel an affinity towards in the looks department or cost. The two brands have a similar approach in regards to not drawing attention to themselves and having very articulate bass. While the REL has a tighter sound I'm not wholly convinced one sub is quicker than the other. It's like we're comparing Ferrari and Lamborghini hear, both cars are fast so the outright performance isn't really a factor and instead most people buy the one they think looks better inside and out :).

[@MajorWebUser]

Just found your amazing channel - brilliant! Great reviews on subwoofers. I've narrowed my search to Rythmik and am unsure whether to choose dual L12s or F12s. I have a small listening room (13.5' x 12.5' x 8.25') running a Hegel H360's 420 watts (4ohm) into a pair of Magnepan .7s. In adding a subwoofer, it has been frequently recommended that given the small space I should add a pair in 'opposing corner' configuration. I love the non-colored sound of this setup but when listening to everything from organ to orchestra, to jazz quartets, to Weather Report, to Zappa, I miss the bass extension I used to get with my Klipsch La Scallas. I'm told that two L12s will sound better than one F12. After watching your review of both of these Rythmiks, I'm torn. My question is whether in your opinion it is worth nearly double the price to go with two F12s. As you described the performance of different subwoofer models, my preference would be to have them 'disappear' sonically. I trust your honest and insightful reviews and would appreciate your thoughts.

[@NemoPropaganda]

F12 for sure! The L12 is excellent but it has a warmer sound where the F12SE is much tighter & quicker with it's transients. Warm subs can sound a smidgen slower, note that sounding slow doesn't mean it's actually slow. The L12 still has very good transients and is a top tier SQ sub for the money but the F12 is what you want for maggies or a T9X if the F12 is too large.

[@MajorWebUser]

@@NemoPropaganda Thanks. Exactly the nudge I needed in order to put a prybar in my wallet : )

I picked up two of these with the GR paper woofer. First system I used it on was Magnepan MMG, tricky to get dialed in and I may keep tweaking the sub but it's every bit as good as you stated. Then I hooked it up with my Vandersteen speakers and it is seamless, added alot of deep freqs. Thanks for your great reviews.

Nice! Just curious, what made you go for the GR drivers? Most magnepan users I've seen with the F12 seem to prefer the original Rythmik designed metal cone.

[@williamkobling8397]

I did not know if I would use it with the Magnepan or Vandersteen speakers and the paper cone might be better suited with the Vandy if I chose to get another set of two channel speakers.

[@2010aloy]

Great review buddy! I've never heard a Rhythmik sub but I have a REL s510 that integrates quite well with Dyn S40s on a primare i35. I sometimes have to check to see if the sub is on or off except for some bass heavy tracks where you can tell its your sub thats making it happen.

[@NemoPropaganda]

Oh yeah, that S510 is no joke!! I just wish that bad boy wasn't so pricey! If anyone has more budget that and the 812 are certainly the next step up.

[@total-rando]

Disappearing and sounding like a bass guitar is actually in the room is what I'm talking about. The "dicohotomy" between movies and music becomes moot when most of the movies you watch have high-quaity/orchestra soundtracks. And even though explosion-fest movies aren't my first choice, when the director's made an effort to make, say, a train going by into a visceral experience (yeah, I mean Snowpiercer), I still don't wanna miss out on that. Totally shopping in the smaller-sub range, though, as my theater room's 11.5 deep x 14 wide x 8 and is in a townhouse (which is decently sound-isolated from the neighbors but I'm not trying to push my luck, hah!) ... Thanks for the Rythmik recommendation earlier!

[@NemoPropaganda]

100% agree but it's unlikely we'll be so intimately familiar with a 2 hour movie as we can be with a 3 minute song so many theater guys just focus on output. But you are correct in that there is a lot of bass fidelity in movies these days and for those who care about that Rythmik is a great option, if you want something on the smaller side for theater and you care about bass fidelity overall a pair of F12's are a damn fine option.

[@mesonto]

It's a freakishly amazing sub isn't it? I'll tell you that these are the subs that make the REL woofer boxes inconsequential. (I say this because unless you go up to an S812, it won't have any base anyway... REL make great wofers but practically non-existent subwoofers) I was amazed when I first heard them too. But a pair of these working with your main left and rights does all your music justice. And to be fair I realize they're not necessarily the best speakers for movies, even two of them, but sound-wise they're better than any SVS, they just won't make your hair on your arms stand up straight. Regardless no one ever talks about these speakers and I've heard most of the high end musical subwoofers and bought a pair of these. Well if they're good enough for Salk, they must have something very right about them. Nice to hear a review of them, thank you!

[@NemoPropaganda]

Hey James! Yeah I agree you'd have to get into the S812 from REL to compete with these, they have the Predator 1508 but the whole HT series as good as it is can't match these in tonal richness and transient detail. And then the T series is possibly the most misunderstood subwoofer REL or anybody has ever made, it's design intention is more speaker reinforcement and not low frequency extension. I ended up jamming the pair in the corners and gained back some of that initial attack I was missing, I'm running them maybe 1db too hot for most peoples taste but to me it's perfect now!

[@michaelp7185]

[@videoproboston2450]

Great review (As usual) and couldn’t agree more! To quote Family Guy, it doesn’t insist upon itself. I had the opportunity to test it with my Klipsch RVX-42 on-wall speakers before my Maggies showed up, and it integrated perfectly width them. I never once said there’s my sub kicking in. With the Maggie’s now that I’ve dialed them in, it’s the same thing. A lot differ than my old Klipsch Synergy 12. When that kicked in it made itself known.

[@777galamian]

Oh, and my main speakers are the Kef LS50.

[@NemoPropaganda]

@@777galamian So the Rythmik is a good bit larger and has more power so it'll be the choice if your room is larger. If the room is smaller the T7 is fantastic! It is worth pointing out some minor differences: Rtyhmik being the larger will extend lower and have more authority overall, REL will be a little more dynamic overall. If you're local to southern california I'd be happy to audition them for you. Both subs have excellent sound quality and can blend extremely well so I'd say get the one you feel more of an affinity for or the one that will look the best in the room as the two are both very good and very similar.

[@777galamian]

@@NemoPropaganda Thanks so much for the quick reply! That'd be awesome to able to audition those with you. Unfortunately, I live way out in Pittsburgh. When you say that the REL will be "a little more dynamic", do you mean that the REL is faster overall? I think what I worry about with the REL is that it doesn't extend very low. I guess I want everything, and it seems on paper that the F12g is both fast and also extends very low.

[@NemoPropaganda]

@@777galamian Both are fast and extend low, by dynamic I mean when amplitude of bass changes that change is more apparent on the REL, it's still there on the Rythmik but a little less. It sounds like you're looking to get just 1 sub and not a pair. If that's the case go for the F12.

I wonder if some of what you notice is the servo reducing distortion. Punch is generally 40Hz to 80Hz+, and with normal subs, you'll get a bit more of the 2nd harmonic. The measurements I've seen put the distortion at negligible levels. I really notice it on my pair on certain movies.

This subwoofer will work for movies but Rythmik does offer other models that I think would be even better like the FVX12 or F15 just to start. If you're not space limited I would even consider something larger like their FV15HP.

ahaha thank you, I'm just hear to help us all stop obsessing and get back to having fun with the hobby. So do keep in mind the F12 can be used for HT but it's intended purpose is music first systems so it's not going to have the headroom of their theater models but as long as you're not trying to recreate reference levels in a medium to larger room it could be okay. The FVX12 will give you better output in a theater environment or the E15 but in my smaller room a single F12 is plenty for movies or theater duty. My room is 12x10 with 9ft ceilings.

How do you like your F12?

@NemoPropaganda I see you have reviwed both f12SE and REL MKII 10"-12" I'm getting ready to build a system, room is fairly small (12x12x7) Fronts Polk R700, Center Polk L400. I listen to about 50/50 music-movies. I will most likely go with a pair of subwoofers, both next to the front stage. I will be using DSP (Dirac) Would you choose one over the other? Reasonings? Both REL and Rythmik have great reviews everywhere you turn which is making my decision a bit harder. Cheers!

[@NemoPropaganda]

If you have the budget for the F12 its worth its higher asking price. F12 has SQ that's more on par with T9X while oferring loads more extension. As far as sealed 12's go the Rythmik F12 is one of the best. The 1205 V2 is right up there with it but its just ever so slightly behind it and that's reflected in its lower asking price so no harm no foul. For those who find the F12 too expensive or not available in their region 1205 v2 is the easy choice. For those who can afford F12's slightly higher price and live in a region where its available will be rewarded with its world class fidelity paired with outstanding extension.

No, I think that GR driver is ugly as sin. One of the biggest reasons I was attracted to the F12 was the combination of that beautiful metal 1piece cone and the lovely piano black cabinet. Rythmik subs are already so fast I just don't see the need for "more speed", hell even their ported subs are lightening quick! My favorite Rythmik sub is actually the ported FVX12.

Great review brother!. Thinking about 2 of these for home theater and music use. Do you think a pair of F12's will give that dynamic punch were I'm currently using JL E110s?

[@NemoPropaganda]

Dynamic punch as in the "wow" experience when the bass kicks, No. The F12 doesn't do that, it's wow experience comes more from how well it integrates which allows the experience of simply sitting back and listening to music without feeling the need to analyze or listen for the bass, it's just there as if it's coming from the speakers themselves. Like this is a subwoofer when integrated properly at times you may think it's off until a bass heavy passage comes and then still you only know it's on because you know logically your speakers can't produce those frequencies but it still doesn't feel like the bass is coming from a separate place, it's just part of the sound experience. Some people will love that but I think some people will miss that "wow" dynamic slam, I guess you can say this is a great subwoofer for people who generally like bass but don't like subwoofers lol.

[@NemoPropaganda]

Hey Del, this is a 12" so it will give you a lot more extension and output while the smaller T9X is extremely good it cannot compete with a 12" from Rythmik as both brands produce subwoofers with world class fidelity. I don't have any opinion nor experience on Hsu research.

What would you recommend close in price range for music and home theater? Thanks

[@NemoPropaganda]

Depends on the room size. This could do HT in a smaller room but if you want reference levels of bass a ported sub will always give you more output for the money. The ported version of this is the FVX12. Quantity of bass is very personal. I don’t listen very loud so 300w or more is plenty for me but some guys like it way louder.

[@induction7895]

Hey Nemo, is this speaker too much for a 12 by 15 by 9 feet room in a townhouses? Or should I be looking at something like Rel T7x or HT1003 mk ii?

[@NemoPropaganda]

I think it'll be pefect! That's a little bigger than my room and I'm able to accomodate single subs as large as 15" easily. Dual subs is where small rooms start to get complicated as you can overload the room very quickly but your room is on the low side of medium so you should be fine.

[@wenzhaochewng2158]

Hi! Not sure if you are able to advise - I have a REL HT1205 for home theatre. However, I am planning to add an integrated stereo amp for 2 channel music. As the REL HT1205 only has single LFE inputs, I will probably need to get another sub for music. I am considering getting the Rythmik F12 for my 2 Channel music. However, as the Rythmik has dual inputs, I'm also planning to plug it into my AVR. Might as well use it since its there, and HT could always do with more output. My question is, do you think the REL HT1205 and the Rythmik F12 could combine well enough for HT?

[@NemoPropaganda]

Hi Wen! The simple answer is YES! I actually used them in a stereo pair (1 f12 and 1 1205) and while I generally don't recommend mixing brands the 1205 and F12 did indeed play very well together and sound very good :). Do keep in mind the F12 can blend a lot higher up so you'll want to keep the cross over low on both subs for the best blending, something like 55hz and below but feel free to experiment, it could be a little different in your room. Do keep in mind the F12 has a few amplifier options, make sure to call rythmik first to make sure you pick the right one for your needs.

Thanks that was an informative review! You said you were only going to talk about the single sub, but can you comment briefly on your experience with the pair of them? Does it improve the experience and if so how? Does running two help with any of the issues you encountered?

[@NemoPropaganda]

Yes of course, running them in a dual configuration certainly brought back in some of initial aggressive attack I was craving and they still integrated wonderfully. Dual subs will also give you more consistent bass from seat to seat and more headroom but I'm only 1 person in a small room so I couldn't test that. LMK if you have any other questions about running them in dual, I own them so I still have them here :)

[@leonthebum]

@@NemoPropaganda Thanks! Have you heard any of the Rythmik 15" subs? I'm considering either the F12s or E15s for my system, which is mostly for music. I wonder if the Rythmik 15" subs like the E15 would be equally audiophile friendly, or would be taking a step away from musicality?

[@NemoPropaganda]

@@leonthebum 15" is just a little too large for my room so unless I get sent one as a review sample I won't ever buy a sub that big for review :( My guess is it's still plenty musical. Reason being a lot of people think a larger cone will be slow and sloppy, well yes it will be if it's cheaply made, flexible, and poorly designed. The Rythmik metal cone drivers are extremely stiff and a 15" will not have to move in and out as much to make the same amount of bass so in some ways and at certain volumes it may be more musical if not just as much. A lot of people say 8" sounds tight and quick, yeah at low volumes. Once you crank an 8" and it has to hit it's XMAX to deliver bass they are among the sloppiest sounding subs. Essentially there are no iron clad rules in this hobby. If you feel more of an affinity towards the E15, go that route, trust your heart! You have a 30 return window either way :).

[@NemoPropaganda]

Hey David, one more thing, I talked to Rythmik and they suggested choosing the size based on where you need to integrate. If you need to blend high up say between 80-100hz the F12 will blend better that high up. If you have larger or more bass heavy speakers that only need to blend between 60-80hz the 15" will be great for that! I hope this helps make your decision easier :)

My system is a separate stereo system only. Looking for the a sub that would have speed and are an enhancement for music. Would the REl or RYTHMIK be the better choice?

[@NemoPropaganda]

Hey Eddie, you've narrowed down your candidates to the two best SQ focused subwoofers in the world, at this point the question is like asking if which is better between ferrari or lamborghini, both are fantastic, similar, and different at the same time. Both subwoofer companies make subwoofers that have outstanding transient response, bass fidelity, and sound exceptional with music. I have not heard the S510 so I cannot comment on that one specifically but if your room is on the larger side perhaps the F12 is a better choice or if your room is more small to medium and you don't want a bigger sub the T9X is a great option. You don't have to worry about how each one sounds as they're both fantastic, instead I suggest you choose based on how they will look and fit in the room. If you are only getting 1 sub and not a pair it is perhaps worth keeping in mind a single 12" will extend lower and play louder than a single 10" so again if the room is larger or you're a 100+dB listener I'd certainly inch towards the larger one.

not at all, the E15hp2 was the most perfect subwoofer I've ever heard. As far as the F12 I still own mine and love it, it's not so much that it's lacking in dynamics, it's really hard to describe honestly, The F12 is just incredibly accurate, it will not exaggerate anything unless it is supposed to be exaggerated if that makes sense? So if you are used to subwoofers that can exaggerate certain frequencies then at first the F12 seems tame but the more you listen to it the more you're like "damn this is great".

[@NemoPropaganda]

I've heard a lot of Rythmik subs but not the E22 yet. I'm not sure what all the difference are between E22 and F12 besides the obvious second driver and different amplifier. I think it depends what room they were in, for example in a really large room the E22 would probably sound better since it can fill the room. In a room where the E22 might be overkill the F12 would probably sound better. I'm really just guessing here but I would imagine it's more similar in SQ and the difference is in SPL. With that said I would contact Rythmik, tell them about your room & usage, and let them decide for you.

At $1000 for music, one F12 or two L12's? Which is going to integrate and disappear into the sound picture better? If I'm crossing over to my mains at 80hz, would a single F12 disappear or localize? (I know. I keep asking you questions on this. Chatted with my dad who sent me the speakers I'm trying to match a bass to. Apparently, he has a Rythmik F12se and loves it. However, he's also got a pair of fancy-expensive bass extenders that mate with the speakers, so he's able to cross over to the sub at 50hz, and not worry about localization.)

[@NemoPropaganda]

1 F12 will beat 2 L12's in terms of integration. 2 L12's will have more maximum output however. At 80hz it didn't localize in my room (hell I even ran it full range just for fun) but every room is a little different. If this thig localizes in your room my guess is just about anything will so if maximum integration is your goal along with low freq deep bass, the F12 is the one.

Hi Simon, your system looks awesome, okay so here we go: Comparison Sub’s: Kef KC62- awesome sub, unless you require something so small most of your money is going to how small it is, but it does sound amazing! Try and audition one if you can. It integrates very well and has excellent SQ, not as good as the F12 but still very good. Kef KF92- Never heard it. I've heard it's incredibly powerful though. Rel Serie T/7x- vs the Rythmik F12SE, well we're talking about the 2 best SQ companies for subwoofers. Both are awesome but we're talking about an 8" vs a 12" so the larger rythmik will have more output, extension, and deep bass especially at the limit. I have both the F12SE and T7X pair in my room. My advice is if you can only have 1 sub go for the F12, if you will do a pair the 7X will be killer and they are intentionally designed to use high-level. Rel Serie S/510- Never heard it.

THANK YOU! Been waiting on this one! So my question is this... While the F12 won't have the same slam and impact as the SVS SB300(which I own two of), in your opinion does it still do justice to bass heavy music? I listen to about 85% hip-hop music and I'm considering these for my "music only" system I'm currently making purchases for. We chatted in the past before you received the F12's and I'd told you how I really love the SB3000's in my living room setup for mixed usage, but I felt like they maybe weren't perfect in terms of blending and speaker integration. I'm really wanting to improve that in this system while still keeping the price around that $1k mark. Maybe I just need to work things out more through SVS's PEQ, but the speaker level connections available from Rythmik seem like a possibly better method to integrate? Anyhow, I know your personal opinion is all you can provide, but I'd be interested in hearing it!

[@NemoPropaganda]

Hey Joseph, I remember our chat :) so the speaker level input is actually not the preferred method as it adds an extra link in the chain and Rythmik prefers people do not use that option unless it is there only choice (like not having pre-outs). So with duals I was able to regain the slam I was missing, at least enough of it to be satisfactory but by direct comparison switching back to a non-servo sub the initial attack was still less. A great example is Put On by Young Jeezy, the first bass note in the intro is infrasonic so you can't really hear it but the second and third bass note come on strong AF! The F12 plays these notes like a gentleman, clean and clear with good amplitude and transient detail and my SB3000 played those notes like a heavy weight boxer landing a right cross. The question becomes do you value that or the maximum integration more? I'd recommend you use different subwoofers in your music system no matter what just because it's more fun that way :D but I think If I listened to hip-hop mostly I honestly might get something like the FVX12 instead but I haven't heard that thing yet but I do plan to soon hopefully!

So, to supplement Magnepan LRSs in a smallish room (11x14x8): 1 F12 or 2 L12?

[@NemoPropaganda]

1 F12 for sure brother.

[@Shoebutie]

Did you review the REL t7i? Wondering how this compares, given similar price points.

[@NemoPropaganda]

Hey Scott, I have not, Might be doing the T5i sometime soon though. The T7i should have similar integration but per it's spec it does not dig down as low in it's freq response.

@@NemoPropaganda love to see your take on the t5i's...considering how much you like subs to have their presence known...at least some presence. I had those things doing the moonwalk on my floor...so they can get there. Though I'm assuming having the gain and crossover almost all the way over probably isn't sustainable.

Rythmic f18 or rel 1508

[@NemoPropaganda]

Guessing this is for a theater or larger room? I haven't heard either but I'm a big fan of both brands. I've only heard the smaller version of each, the F12 and HT1205 and in that comparison the F12 is the better by a fair margin, it's also a good bit more expensive though. Not sure how that plays out with the larger models.

[@figaro8119]

What size room can the F12 handle? My room is about 20w x 30d x 9h. Rythmik advised me to use F15. Your room is how big?

[@NemoPropaganda]

depends what your goals are and how much bass you want. Do you have any particular goal of hitting a specificl SPL at a specific frequency? It's a very capable 12" but that is a very large room you have.

Nemo Thoughts on dual pairing with your Buchardt S400?

[@NemoPropaganda]

Hey Paul, so dual F12 was one of the better pairings I've had with the S400. In my room the S400 are incredibly strong down to 30hz and the F12SE lets you adjust the frequency cutoff as low as 25hz with a 24db slope so while that may sound extreme that's how I set them up and they did sound fantastic. You have to be careful with gain at that point though as you don't realize how much sub 30hz bass you're adding until it you hear a track that has information that low and then you're like "oh shit" so it took some fiddling to get the gain correct but yes I think it's a good pairing!

[@chrisrichardson958]

Excellent review! Quick question for you I’m debating 2 rythmik f18s they are sealed so I’m wondering would they be good for theater or would the ported version be better ? I’m leaning to the sealed because I’m not a fan of port noise . Thanks Chris

[@NemoPropaganda]

The F18 is a theater first model so a pair should be plenty good, the youtuber SpareChange kzbin.infovideos will be reviewing a pair of F18 in the near future so keep an eye out for that. As far as vs the FV18 being the ported model it will have significantly more maximum output and rumble as all ported subwoofers do. As far as port noise I don't think you'll be pushing these to such a limit but It might be a good idea to reach out to Rythmik and get their opinion on that.

So what do you think would sound best ported or sealed subwoofers I definitely want to go duel also what size woofer would be best ? Any thoughts I would really appreciate Thanks bud Chris

[@NemoPropaganda]

@@chrisrichardson958 A pair of F18 in that room would be plenty good :) And per Rythmik they have about the same output as a ported 15". As far as what will sound best it's really a personal choice. Ported always gives you more rumble down low for infrasonic bass if all other things are equal and I take an approach of aesthetics first so you may not find my personal opinion the most valuable but in a room that size I would do dual F15HP simply because I think it will look better :D

READ THE PINNED COMMENT

[@Cujobob]

They make amazing subwoofers IMHO. A lot of people will prefer boosted bass, but that doesn’t mean they shouldn’t get a sub like this. It means they should use EQ.

[@NemoPropaganda]

ahahahaha, that's not a bad idea!

[@jerryjohnson4625]

I was kind of interested in these subs but not now. After calling and leaving a message in Texas , got a call back. He said how many watts is your tube amplifier? I said 35 watt premaluna. He said sorry, you have to have 60 or 80 Watts. Huh ? For a signal? Call me ignorant. Those expensive Rel subs I had Worked with just a signal from my amplifier. So did my pair of SVS subs , so does my Emotiva sub.

[@NemoPropaganda]

I don't understand how that's bad service? Sometimes while unfortunate a manufacturer must say when a product is incompatible with their gear. I respect them for being straight up with you and not wasting your time with a "maybe it will work" type answer. Did you try asking them why 35w would not be sufficient?

[@jerryjohnson4625]

I just didn't know a powered subwoofer had to have 60 or 80 Watts of power from my amplifier. I thought subwoofers just received a signal from your amplifier. I've never heard anyone mention in any of the reviews that you need a minimum of 60 watts on your amplifier to make this Sub work. He offered no explanation and I wasn't really wanting one. It saved me a lot of money. My Emotiva sounds great. Happy listening.

[@jerryjohnson4625]

I don't think I said it was bad service. It was just an odd thing to me.

[@NemoPropaganda]

@@jerryjohnson4625 my mistake, I interpreted it that way, it seemed you were a bit frustrated by them. I'll say this though, if you need high level inputs REL is the best sub to get. A little expensive if you want the same output the F12 has though.

[@franklandgraff1190]

I have a vintage Rotel receiver that doesn't have sub outs. Will this still work on my system?

[@NemoPropaganda]

Hi Frank, yes you can but you have to select the model that says "Upgrade to A370PEQ3 amp with speaker level inputs" which adds $40 to the cost. From there you would feed the subwoofer a signal off your amplifiers speaker outputs.

I'm not sure, SVS has sent me stuff in the past but they really don't need guys like me and when a new product is released sending me a review sample means 1 less customer gets a subwoofer as there is generally limited stock on launch.

Nice review. Sounds like it does it's job 'too well'. However, if the bass is or is not there, the job of a sub is to play what is not is not there! Thanks!

Do you know what the power consumption of this subwoofer is?

[@NemoPropaganda]

I do not, that is a better question for Rythmik tech support.

[@MOAB-UT]

The value F12 is Class D supply. The F12 is A/B so it will use more energy. I don't think you would hear a difference- maybe just a touch on paper.

[@SantanKGhey1234]

Nemo, pair of these or pair of REL T9 for music

[@NemoPropaganda]

The F12 is larger and far more capable as a subwoofer overall. The F12 can extend substantially lower and play much louder. As far as the sound difference the biggest difference is this: The T9X has warmer tone to it that gives a sense or richness to the sound while the F12 is the more accurate sound. Both have excellent fidelity, nuance detail, great handeling of delicate passages, and incredible speed. The F12 is the better subwoofer however some users may prefer the warmer sound of the T9X. Personally I own both a pair of REL T7X and a Rythmik F12 and I still can't decide which setup I like more so when I tell you they are both incredibly good I really mean it.

@@ColocasiaCorm Both are absolutely outstanding in terms of sound quality however lets remember the T7X is an 8" and you cannot expect it to have the same output or extension as the 12" F12SE. Even if you had 4 REL T7X you would not have the extension or output of dual F12SE.
