Best Subwoofer under $500 for music and movies. RSL Speedwoofer 10s MKII Review.

[@NemoPropaganda]

**Pinned Comment** Everyone keeps asking about how it compares to the SB1000 Pro, It's fairly staright forward: I love the SB1000 Pro and it is in fact my favorite SVS subwoofer, it has a ton more features by way of the cell phone app and is much smaller so it's great for anyone with a major space constraint. While both are great subs the RSL being larger will have more output overall. SQ between the two is similar enough. I suggest you choose based on physical dimensions or features if you need them.

[@EDCAssociate]

Literally was gonna be my question. After the video. What about a used sb2000?

[@NemoPropaganda]

@@EDCAssociate hey bro, that's a tough one, I've never had both subs here at the same time. My memory is a little hazy but I want to say the RSL still has a thicker bottom end because it's ported while the SB2000 Pro had a little more in room extension and a slightly cleaner sound. I really couldn't say with any confidence which one was outright better but if my memory is service me well the SB2000 pro should take the edge. Really take this with a grain of salt though.

[@rjzlwop3153]

So are you saying that this sulfur is not as good as the SPS 1000 Pro? And I believe this would be the subwoofer you and I were discussing previously? I’d like to review a lot thank you for sharing

Great review as always. I have a MkI and a MKII, also have dual SB2k’s and two lower end Elac 10s for the bedroom, have had some Polk junk.. have listened to many over the years and I will concur there is absolutely nothing that comes close to checking all the boxes: construction, power, depth, control, size and not least, customer service as a RSL. When they did the preorder the website crashed and when I called late in the day they were all sold out. Whomever answered the phone said they anticipated that and put a few away for customers that couldn’t order online. Absolutely stellar.

I had the best experience with the RSL folks. Fantastic customer service.

Out of all reviewers I was hoping to get a review of this new RSL sub from you and you came through. In fact you're the only person to review this so far that I know of. It looks like RSL did it again. Wow! I bought the older model based on your review. This is a great company. It's a crime that they are able to sell these for the price they're going for.

[@NemoPropaganda]

Thank you for the kind words Anthony, I totally agree!

[@billmcginley]

I used to go to their showroom in Canoga Park back in the 80's. They had a couple of sets of JBL's on their wall of sound and in many regards the JBL's sounded better but the RSL's sounded pretty damn good too- especially since they cost much less because you bought them directly from RSL. After that showroom closed I assumed they became extinct like ADS or Boston Acoustics.

[@capnsnaxx]

@@billmcginley yeah I do believe they did sell the company off to someone else and bought it back from what I heard. But they are an amazing company. I wish I could have seen that showroom.

[@B.A.Bassangler]

Well I finally took the plunge and just setup my new RSL10sMKII. I had to put in in a corner, but with a really low gain setting, (a pinch off of, off), WOW what a difference. I'm no electrical engineer, but there has to be something about 400W making such an improvement at such a low gain. Don't just buy for the quality...RSL's customer service is top notch. Joe Rodgers answered my email's promptly, and helped with some mounting solutions for my bookshelves (CG-23's). Starting out with speakers crossed over at 90hz, and SW a touch over..."Shine on You Crazy Diamond" is sounding magical...what more could a guy ask for? I owe you a few bones for all your review help...see you next payday!

[@racerex100]

I have one of these on order. Should receive early next month. I thought I was going to get the SVS SB 1000 Pro. Never heard of RSL, but somehow ran across their site researching for a nice entry level sub. I wanted to raise the level of my modest 2 Chanel system. A PS Audio Sprout100 with a pair of Elac UB5’s. I rebuilt a vintage Pioneered turntable and the system sounds pretty good. But as usual, looking for that next level…. It never ends. Anyway, nice to hear very good reviews on this subwoofer. Thanks for taking the time to review…

The Speedwoofer 10S MKII I got a week ago is an awesome sub! If you didn't see the size of it and just listened, you would think it is a larger subwoofer. I am just running it in a 2.1 configuration.

[@theboatyboat]

I passed on a used PB-2000, half because I could not be sure about the unit's abuse history, but also half because I haven't heard anything negative about the Speedwoofers. I prefer the output of a 12" woofer, and if RSL ever gets a 12" to market I would definitely be hopping on the train for one. I'm really looking forward to hearing some really clean punchy bass again. My old 12" has seen much better days, and I've no real use for low frequency extension as it'll be in a 2CH setup. Thanks for the review, I haven't seen a MkII review pop up before yours. :)

[@NemoPropaganda]

if you don't need the extension a pb2000 would be overkill, it's greatest strength is it's ability to rumble!!! If you're looking for more SQ and don't need gobs of low end extension look at the REL TX range.

[@NemoPropaganda]

it depends what you value and what your budget is. If you value output & extension then the ported RSL will be the easy choice. If you're not so worried about max output or extension and are instead more focused on having the best fidelity & sound quality then something like the REL T/X range is an easy choice. They're both really good but also very opposite.

[@luisnarvaez4762]

Ok first of all I want to let you know that you are one of the most articulate, knowledgeable sub woofer reviewers I’ve ever heard of or seen,keep up the great work brother! So here is my question, I do have an RSL Speedwoofer 10s. I also have 2 Velodynes spl 1000 in immaculate condition a little while ago I did a little test at more than reference levels on both Velodynes and they still impressed me, then I turned them off and decided to test the RSL Speedwoofer…. And to be honest I think the RSL Speedwoofer almost kept up with 2 Velodynes spl 1000, like I said these are in immaculate condition. Do you think 2 RSL Speedwoofers would tell me about to forget about the ol skool spl 1000’s? By the way I’m talking about 15 years old subs, but if you know about subwoofers, these little things were the shiet back then. Will definitely appreciate your honest response.

[@NemoPropaganda]

Hey Luis, so the SPL range from Velodyne was good for the time, tons of output in a small package but they were very monotone. Changing the freq knob almost has no impact on the overall sound. The subs tend to make the same sounding bass just at different volumes. Personally I'd buy another speedwoofer and sell the old Velodynes.

[@tycheesey]

A rear port is pretty odd to see in subwoofers. Looking forward to your thoughts!

[@NemoPropaganda]

Rythmik L12 is a big upgrade over the Speedwoofer in terms of SQ & nuance detail. The sb1000 pro has a ton more features so if that matters to you that might be worth the extra $160 but the RSL is a little larger and a ported 10" outperforms the smaller sealed 12" in this particular comparison. The RSL is hard to beat.

So happy you reviewed this, Nemo! I've had mine about a month so far. It's almost too much output for my tiny apartment. We talked previously about the R100 vs. R200 and you recommended the 200. Well, I threw caution (and wallet) to the wind and ordered R700s that arrive in 2 weeks. I read the R700s come close to full range, so I'm curious to see if I feel the need to keep the Speedwoofer after some A/B testing. P.S. I almost went with the SVS SB-1000 Pro over the MKII, as it seemed to be the common recommendation for a mid-tier sub, although they recently bumped the price to $600. How do you feel the MKII compares to the SVS, Nemo? Thanks for the honest and straightforward review.

Hi Jerry, I think you should watch my Tzero review again, it should be pretty clear why I did not make the comparison. The Tzero isn't really a subwoofer in the traditional sense. It's a 6.5" driver that slightly thickens the sound and helps bring out some nuance detail. The Speedwoofer is a proper subwoofer capable of shaking your windows.

[@NemoPropaganda]

RSL 12s is roughly 5x the size of the T9x, if you don't mind a sub that big for a bedroom I say go for it.

[@NeilBlanchard]

The cabinet has a slot opening, but it is more accurately called a mass loaded transmission line. Which is why it has better qualities than most ported subs.

[@NemoPropaganda]

I don't mean to be that guy but this is not a mass loaded transmission line. T-line enclosures are much larger, the air mass acts as the spring (like a sealed enclosure) and the low end roll off is 12dB (like a sealed enclosure). What we have here is a a slot shaped port tuned to whatever RSL decided (maybe 26hz or so) with your typical 24dB low end roll off and the port loading acting as the spring.

[@NeilBlanchard]

@@NemoPropaganda It is not a "classic" TL, to be sure, but the diagonal baffle inside, it is a variation on a "new style" TL. The driver is located about 1/3rd of the way away from the closed end (the triangular space near the driver) and then there is the second triangular space the begins the open end of the TL, and then the fairly long slot that is the terminus opening. These are definitely not "just" a ported design. The added mass of the moving air in the open end of the TL *lowers* the fundamental frequency of the system, and since the air in this part of the cabinet is moving in *unison* with the driver - it does not act as a spring. Only the air in the closed end does this. I have designed MLTL speakers, and the "new" style designs are able to be be smaller than the old school type. They have lower distortion, as well. What goes on with these designs is far more complex than meets the eye. The distance on the outside of the cabinet, from the center of the woofer, to the center of the terminus opening causes cancellations of a series of harmonic spikes, and when done correctly, the total output of the system is quite smooth, and the output of the terminus opening is in phase with the driver. All the volumes and dimensions of the spaces on the inside are important. In particular, the volume of the last section inside the slot allows the tuning frequency to be pushed lower than the Fs of the driver - which is not the case with typical ported designs - and certainly not with sealed designs.

[@NemoPropaganda]

@@NeilBlanchard interesting, I will admit my experience with T-Line is very limited and I have not read up on the topic in a long time. I do know cabinet design can be fairly complex and can have a huge impact on the sound. Thank you for sharing that.

[@NeilBlanchard]

@@NemoPropaganda I use a program called Hornresp, which has been refined and improved for decades. You put in the full Thiele/Small parameters for your driver, and input the areas at the key sections, and the distance at the centerline between them. Hornresp is doing calculations at all frequencies between 0-1000Hz - many thousands of not millions of calculations to produce the predicted response. It includes the path distance on the outside of the cabinet between the center of the woofer and the center of the terminus opening, and it has an accurate model of polyfil, as well. It can tell you the velocity of air at the terminus opening, and cone excursion. The key innovation in the new design is, as I mentioned - moving the woofer from the closed end, to about 1/3rd the way away from the closed end. This can essentially eliminate the strong dips that were almost always present in the old designs. And tapering the section down smaller than the driver Sd has the effect of making the TL act a lot longer. This is the mass loading - the cone is acting a lot like an open baffle at higher frequencies, but it progressively adds mass as the frequency drops. The results are much better than it would seem possible. Since the terminus opening is outputting a range of frequencies, and the slope can be controlled, when you get the room lift, you can avoid "room boom" and get lower extension, as well.

[@NemoPropaganda]

@@NeilBlanchard well I certainly seem to learn something new everyday, thank you for explaining all that.

Please get one for review, however you can! I'm in the market for a sub but may wait to see how they perform. Although I don't think they've said anything about a release date. They just unveiled them at the Schiit/Emotiva Texas Round Up event they had(well, it's actually going on today, 7/23, also).

Now that has me EXCITED!!!!!!!!!

[@themastroiannis]

Great review I had missed watching! Got me intrigued and I have a question for you: I replaced a B&W ASW608 sub with a REL T5x. difference is huge and I love the integration of the REL to my system, the speed and texture the bass has! All awesome, but I have a serious issue with the REL. The transformer is noisy and I am able to hear it even 9ft away!! Drives me nuts! hearing that very faint "humm" in my bedroom convinced me I need to get rid of it! By the way, REL changed the transformer for a new one but I still can hear the "humm". Do you think this RSL would be a good option? or does the Rythmik L12 would be a noticeable improvement? or any other suggestion under $800? It would be used exclusively for music in a bedroom setting. Definitely more interested in quality of the bass than quantity. The speakers are a pair of KEF LS50 meta and the amp is a cambridge CXA81. As always, THANKS!

[@NemoPropaganda]

No this RSL would not be a good option, while its very good and capable of a lot more bass output and extension than the t5x the sound quality difference is too far away from the T5X. Hmm, that's unfortunate that you're experiencing transformer hum, if the plate amp has been replaced and its still doing it theres a good chance its something in the home electricity or your sound system. Your high level cable isn't all coiled up is it? Have you tried swapping to low level to see if that makes any difference or disconnecting signal all together? If you disconnect all signal and it still does it then try a different power outlet, try a different room, try using a power strip, etc... this will help isolate what the problem actually is. Anyhow I digress. The L12 will be on par in terms of sound quality and is a very reasonable alternative that will offer up tremendously more extension.

[@themastroiannis]

@@NemoPropaganda Hey thanks so much for your prompt response! a-p-p-r-e-c-i-a-t-e it!! tried absolutely everything as I love the T5x! different outlets, different rooms, power strip, have been in touch with REL customer support (great customer support by the way) and they changed the transformer but informed me the REL T models do have a tiny bit of noise coming from the transformers. For me, it's unacceptable... it's just too loud. should be dead silent. will check the L12 as I've really given up on the Rel.

[@NemoPropaganda]

@@themastroiannis that's a bummer but I understand, mine hums ever so slightly but I can only hear it when I'm up against the subwoofer making adjustments to it and my ear is like 1ft away but I also have a fairly well damped room. The L12 is the cheapest sub that has similar SQ, I think you'll like it a lot.

Nice video. I have the older model SpeedWoofer and I am happy with it. How do these compare to the SVS Micro 3000?

[@NemoPropaganda]

Micro 3000 is about having big bass in a small package, if you have a space limitation or just want a really small sub then go for Micro 3000, otherwise a bigger sub like the RSL or even SVS's own SB1000 will have more output.

[@t0nyxgq]

Thanks Nemo for another great review. How does it compare to the REL HT 1003? Both 10" and seems great for HT. The REL is only $100 more MSRP on sale right now @ $549. If it was your money, which would you buy if you can only choose 1?

[@NemoPropaganda]

I have not heard the 1003, only the 1205. Vs the 1205 the ported RSL has a more pronounced bottom end and should have more output overall, that's no surprise as a ported 10" generally can outperform a sealed 12" all things being equal. The RSL is the easy choice if output & extension are primary concerns (theater) on the music side of things the the lighter weight moving mass and fast filter set of the 1205 will make it an easy recommendation as it can blend in with damn near anything and integrate amazingly well.

[@pedroluisguillemain5683]

I upgraded from an AudioEngine S8, to this Speedwoofer MKii, and it's way better, and it hits good enough for my desk top setup They're plenty loud, plenty deep, and look nice too. I'm a bass head, and listen to mostly hip hop, 70s rock, and Mexican Corridos, and this great for all of those generes. I also own two PB3000s too, and they sound much louder, deeper, and cleaner, but obviously the price, but if I were to redue my purchases I would've just gotten two of these and that would've been more than enough for my space. I still wish (Persuit of the perfect system never stops) would've tried a REL and Rythmik, but buying and returning just seemed like too much hassel and just stuck with the RSL.

To be honest I’m going to put it around $700.00 bucks based on reviews and my own experience.

[@NemoPropaganda]

Speedwoofer has more output and extension than any of the T/X subs but all the T/X subs have better bass fidelity overall by a fair amount. As far as the next logical upgrade from the RSL it would easily be the Rythmik L12 which brings more bass fidelity to the table.

Since you're mostly on the theater side of things I'd lean towards the RSL because it's sound quality is good for the money and its output is great for the money.

[@lukeselker5175]

Just the parts for a sub like this: Comparable plate amp: 200.00 Driver: 160.00 Enclosure materials: 80.00 That already puts you at the cost that they are charging, then you have to factor that they are shipping it to you, providing customer service, providing their expertise and designing the product, paying someone to manufacture it.

music only? Keep in mind all subwoofers have a sweet spot, if you have them turned down too low because the room is too small for them it's like driving a sports car at 5mph. Theater doesn't have this problem because their dynamic swings are much more extreme. With that said I would not run dual SB3000 in that room, those subs sounds best at louder volumes. Vented subs on the other hand tend to have a wider sweet spot and are happier at a wider range of volumes so the RSL 10s would get my vote however if you have dual SB3000 money why not get a pair of Rythmik FM8 or REL T7X or on the cheaper side REL 1003 MK2? Personally I'd want a pair of smaller subs in that room since positioning will be so important.

[@w7mjr]

Another great review. Thank you! I have a question for you on the MKII (I apologize if you already addressed this-I didn't see it). The MKII seems to have a new LFE DSP mode. When you set the crossover to LFE (knob switched ccw), the DSP increases low range gain and extends bass. With LFE switched off, the MKII is supposed to behave more like its predecessor in so-called "music mode." And if you low pass from your preamp, you just max the cutoff frequency on the sub. for "music mode," i.e. LFE switch off on sub. My question is did you compare these two modes at all? And would the "LFE mode" only be appropriate for HT? I'm mostly interested in stereo music listening and 2.1ch TV watching. I have an Emotiva USP-1 preamp and was thinking of using its bass management to blend Arendall 1961 bookshelf speakers with the Speedwoofer, since MKII is just within my budget (if I can get my hands on one!). Then I start thinking to myself, maybe I should wait and save up for a Rythmik L12. Cheers!

[@NemoPropaganda]

my preamp doesn't have any bass management so if I set any sub to LFE it just plays full range so I I was not able to test that. I do also use my system like you for music and 2.1 TV. With the arendal 1961 you will need to blend high and the L12 has a much better midbass region than the 10s so I do suggest saving a few more shillings and going for the L12 instead.

Looking for a SQ, that offers a little thump but won't pound the house down. Something with a fast tight sound over boomy. Main focus is music, not really interested in home theater. I was sold on the B&W ASW608 after watching your vid, but then read your comments and saw the recommendations for newer products... so figure I would ask you instead of guess. Smaller is better, but not opposed to any suggestions under $500.

​@@thatprimalmanthejfmfiresmo9230 no, since its vented the rsl will have a fuller sound at the lower freq regardless of volume.

@@NemoPropaganda that is exactly what I needed to know. Thank you so much for your replies to a question that you answer constantly about these subs.

Close to pulling the trigger. If I can squeeze-in an RSL-SW10 I will, else I know I have room for 2 SE-8's...either way thanks to your reviews I'm sure I'll be happy either way...on to my "specific question" as asked...I seem to remember reading on RSL's site, recommendation for placement from the wall for port clearance, but can't find it now. Do you have any idea what it is, or am I dreaming?, because I can't find any mention on their site?

4 to 5 inches from wall…

1 Speedwoofer will outperform dual SE8's easily.
