Rythmik F15HP Home Theater Subwoofer - FB Marketplace $500 - MSRP $1,282

[@BloopsnBleeps]

I just ordered 2 of the Rhythmik F18's. Coming from 2 Klipsch ported 15's. I wanted the ported versions of the Rhythmiks but they are too big for my space. Hoping they can dig deep even though sealed. I hear they are gonna blow my mind.

[@Luke-qs2cg]

How did they turn out? I've got a 12 inch rythmic getting built right now

[@BloopsnBleeps]

@@Luke-qs2cg I cannot believe the difference in the quality of bass these put out. Having the 18 inch gets down to the low frequency I've missed but they are so clean and not boomy. It's honestly unlike any home subs I've heard. If you have the means, definitely get duals.

[@dayonerecoverdub3626]

My friend has those in duals well the ported version and they are incredible

[@blazermdx]

I have the ported version in storage, the FV15HP. Rythmik makes spectacular subs. You’re lucky, my friends all have Sonos. Haha!

[@AudioElectronicsChicago]

just by looking at it, I can tell it is very powerful

[@dickydoesaudio3466]

Thats a nice sub. I'm not a big fan of sealed subs, had a Svs sb12 that I wasn't very happy with. Something about these rythmik subs, is just very intriguing to me though. I might need to look into these in the future. Nice review.

[@thepiecesfit5049]

Love Rythmik went with the E15HP for space considerations it’s only half a dB less output. Itching for a second one!

[@blazermdx]

You have excellent taste! Rythmik is an excellent subwoofer company and their subs are just awesome. Duals is the only way to fly so I’m excited to hear that’s the direction you are headed. Rythmik also offers a return client discount of 10%, which is nice!

[@muffemod]

I'm getting two F15HPs and YOU CAN'T DO ANYTHING TO STOP ME!

[@blazermdx]

And l wouldn’t even try. Haha! They are excellent subs, I’m excited for you!

[@mattmiller2761]

Thanks for the review. Getting ready to replace my 19 year old Sunfire Signature Sub (the 13" one) with either a Monolith M215 or a Rythmik FV25HP. I'm going big. Tough decision. There's not a lot of Rythmik sub reviews out there. I'm thinking the Rythmik is probably the way to go though.

[@blazermdx]

You’re definitely going big, if you’re going to grab either of those monster subs! I don’t have any experience with either but going off other people’s comments and my Rythmik experience, I’d probably lean towards the FV25HP. I’ve been reading complaints about Monolith customer service, but again, I have no experience there. I know Rythmik has the performance edge, customer service and a better warranty which Is why I said I would lean that direction. Either sub is going to have more output than about 4 - 6 of those awesome little Sunfire subs:)

[@edwarner504]

I was really considering the ported version but funds didn’t allow. Went with mono 12 instead. One day I’ll give this servo tech a try!

[@blazermdx]

Those Monolith subs sure do have a devout following. I can’t wait to get my hands on one of them. I live Rythmik subs, if you couldn’t tell but I still think Monolith and HSU are the top of the heap when it comes to price/performance. You have excellent taste in subs, my friend!

[@SoniclayersMusic]

Did you prefer this model over the ported FV15HP? I am currently testing a pair of the FV15HPs to replace my F12s sealed. The F12s still sound tighter and have a very fast attack. The FV15HPs are deeper and smoother. Love to hear your thoughts..

[@Lowkey_nxthxn]

[@Quetzalcoatl0]

Most people don't need to reach 115db at 10hz so commercial subs are perfect. But from what i've tested and experienced, a single sub can give you enough, but going dual is a minimum for me, not for the power and spl but for when you calibrate them so fix each others nulls. To make each seat have the same bass. I've been living with a single pb-1000 and i was happy for 2 years. It's perfect for moderate listening to around 100db. Most people in Europe live in apartments and can't make loud noises, and a single pb-1000 is way way enough. Going quad 18s in each corner is the best thou. :P

[@blazermdx]

Very true! I think the forums and the other audio groups have really made things confusing on people starting out in this hobby. For folks like me and you, where we don’t have unlimited space or dedicated theaters, you can still accomplish near theater level listening without 4 18” subs. Two good subs, properly positioned and setup, will meet most expectations and then some. I also don’t like going much above 100 dB anyway, starts to get uncomfortable. We are missing out on the real deep stuff but if you’re sharing a wall or two, we don’t need it anyway. With that all said, if I ever buy a house big enough for a dedicated theater, 4 18” woofers, here I come. Haha! Thanks for stopping by and for taking the time to comment. I really appreciate it!

[@nonametofame]

How about a comparison video in the future? I know you're limited on space, but if you happen to have two comparable pieces of gear at the same time, it would be a nice change up from the usual reviews. Keep up the great work!

[@mpa_21]

I love servo subs; I heard from my friend DD+ 18 from Velodyne and its insane. How I wish they sell Rythmik here in New Zealand.

[@josealfredfernandes]

I own Rythmik F18, they claimed it's better than Velodyne Acoustics DD+18 at 1/3rd price.. is it true?

[@mpa_21]

@@josealfredfernandes I'm sorry I can't really compare it myself as I haven't heard or owned Rythmik subs. I only heard it in youtube videos. However, with such great reviews I have no doubt it's better.

[@willgatlin8229]

Do they make an 18 inch dual sub in piano black? 0:45

[@lesmatthews459]

The reason SVS is so big is do due their marketing! They have a great sub - but so do other companies.

[@blazermdx]

Very true! I just love their quality and customer service, but there’s definitely some pretty awesome subwoofer brand options that tend to go under the radar. It’s like the old 60’s horse power wars but for home theater subwoofers. Great time to be a home audio consumer:)

[@jasonsullivan8001]

I have 2 gsg Marty cubes and I’m thinking about changing to two F18’s.

[@Damien-Lugnut]

Wonder why they discontinued the Rythmik f15hp

[@robmbc]

Thanks for your videos and I really enjoy them. I have a suggestion on your sound bass scoring. How about a score how how well and loud can play 20 Hz or below? Just a thought. Thanks 👍

[@blazermdx]

I’m trying to figure out a better way to describe the 20hz range, as I know how important that range is for movies but I haven’t figured out that might be a little confusing to beginners. Plus, I don’t have proper measuring equipment that I feel would as accurate as needed. Definitely a great idea and definitely something I need to start incorporating. Thanks , my friend!

[@snauspockets9924]

And this is why I love and hate aluminum woofers. I have some really nice rbh sound speakers and I was using a Swiffer duster on them. I sneezed and my hand moved and the plastic tip lightly smacked against the woofer a little bit and put a little tiny dent in it. It's tiny and no big deal sound wise but I can see it clearly from 10 ft away because the woofers are so beautiful and perfect otherwise. Makes me frown every time I see it so I keep them covered up mostly. Other people don't even see it it's so small but I sure do. I just ordered a PSA sub over a Rythmic sub and one of the considerations was that the rhythmics had aluminum drivers.

[@liquidsnake1123]

@@BloopsnBleeps still just have one f18. Have no issues at all. Still having fun with the bottomless bass it puts out. When i move ill be getting the 2nd f18. But youll be very happy with two f18s. It really is pretty much flat down to 10hz or even 8hz. With two f18s youll be flat to 8hz no problem. If your coming from a cheap $200 sub to two f18s your gonna be blown away. Rythmik is not lying when they say " Brute force Finness". Playing video games and feeling the floor shake when it should if there is a big monster or explosion actually helps me play certain games better lol. So yeah im very happy with it still. I really dont think i need another sub for a very long time or ever. Two f18s is my end game for subs.

[@bric7244]

I like that you do reviews on Rythmik & hsu . I m leaning towards the hsu VTF-15H Mk2. Can I ask were are you getting all this used gear at. I m looking for some amps . Thx man.

[@julianjosephs8822]

You seriously need to do a comparison with the sb16. You'll be the only one to ever done it.

[@blazermdx]

I would love to but unfortunately, with how much all this gear is costing and the limited amount of space I have to work with, comparing these large subs directly isn’t an option available to me. Trusts me, I would have loved to have been able to compare this Rythmik to the SB-16 Ultra I’m currently testing out. If we can keep growing the channel, doing comparison videos would definitely be something that I would want to offer. Thank you for staying by!

[@nathaneldogo]

Rhythmic vs svs What is better ?

[@Bryan-hd7nm]

Great video! Do you like dynamic eq option on the denon? And do you like the effect that has on the subwoofer? Thanks! Great work!

[@blazermdx]

I usually keep the Dynamic EQ off as I feel it over exaggerates the bass. With that said, with how frequently I swap out equipment, I have actually enjoyed it on with some subs and speaker sets. One of the problems with trying out so much gear, is that it’s hard to keep the speakers that are usually in my system, sounding good. I’m tired of calibration at this point, haha. I say mess with Dynamic EQ and see what you like the sound of, on or off:)

[@dannyr2272]

How would this compare to the rythmik fvx15 ?

[@blazermdx]

Excellent question! Unfortunately, I’m not the one to ask. I will always, only speak on subs that I’ve owned. And I haven’t owned the FVx15. Im in a smaller space though, so I’d likely lean two red the F15HP in my foot. But again, I haven’t owned the FVx. How large is your room and how loud do you listen?Would you ever add a second? Interesting fact, I was one of the first owners of the FV15HP, at least I was one of the first on in WA. Best Dulin I’ve ever owned.

[@herrtrigger7220]

What's it going to take for somebody to simply measure max SPL of SVS, Rythmik, Hsu and PSA subs in the same room? No MIT lab crazy graphs we don't understand, just max SPL at 15, 20 and 25hz? Why is everyone so scared to ditch the platitudes, parsed verbiage like 'for the money' and subjectivity?

[@hitt2188]

Hi I have a rhythmik h600xlr2 directservo 15 inch subwoofer . Can you give an idea how much it worth

[@blazermdx]

Rythmik has a very good reputation so they generally sell for 70 - 50% of the MSRP. If you have a FV15HP, which has a MSRP of about $1,800, it should sell in the $1,250 - $1,000 range. That’s just an estimate but should get you close:)

One of these days, I’d love to hear one of those beasts. Monolith really did something special with their new subwoofer lineup. With how many Monolith subs that have sold, I’m sure it’s only a natter of time before they hit the 2nd hand market. I’m just waiting:)

That is a great deal, considering their age and reputation. I also believe the Monolith warranty is transferable, if the seller helps out but you’ll need to verify that. Just what I’ve heard. Nice choice on subs, my man!

I really like both ported and sealed but I tend to lean towards sealed, for whatever reason. Probably because my room is smaller. Ported subs usually have quite a bit more output, apples vs. apples.

Not quite sure what you are referring to. Did I come across as negative or as being a Debbie Downer in the video?

Anyway, thanks for stopping by and for taking the time to comment!

[@iyona14granturismogt6gtspo7]

Poor quality, the fact that a hdmi cable could permanently damage something that is supposed to rock solid...

[@blazermdx]

Nope. Definitely not poor quality. Rythmik uses aluminum for the woofers due to the light weight nature and the structural rigidity, when formed. These aluminum woofers were never intended to take side impacts, so this was 100% my fault. That would be like saying a GTR is poor quality if a shopping cart impact causes a dent in the door. Just needed to clarify that decause Rythmik subwoofers are opposite of poor quality. The sharp edge of the HDMI was just enough to cause the dent. I would imagine it would have dented polypropylene woofers, possibly torn paper woofers. Probably wouldn’t have done much to the massive woven SB16 Ultra I reviewed but that is just because the woven material is a little thicker.
