Rythmik LV12R​
By Jim Wilson (theJman)



To quote the oft repeated line from the famous (infamous?) ring announcer Michael Buffer; are you ready to rummmmble?. You had better be if you buy the Rythmik LV12R, because it certainly is. This subwoofer combines power, depth and poise in equal parts. It's on the large side, and a bit generic in appearance, but for sound quality it's the yardstick to use when measuring any subwoofer costing less than $600. The Rythmik LV12R is nothing short of amazing, and well worth the asking price.

Great review -- thanks. I've been intending to DIY boxes for a pair of F15HP clones for quite some time now, in a room about the same size as yours, and it appears from this review of the most entry-level Rythmik that I will not be disappointed. And congrats to Rythmik for making even an inexpensive, accessible sub worthy of such a great review on audio quality.

I very seriously doubt you'll be disappointed, especially if you're going to have dual F15HP's in a room that size. Make sure all your pictures are secured properly, otherwise they may end up on the floor... :D

About to find out how amazing the LV12R is - mine is sitting at UPS waiting for me to pick it up tomorrow! Jman's review pushed me over the edge on choosing it - great review!

Since I'm replacing a 10" BIC sub which fried the amp after 7 years - I will probably be thoroughly impressed. I've been bass-less since March, so looking forward to it - a lot!

Another fantastic review Jim. I've been waiting for this one for a while now. It really has me interested in what this thing can do for such a low price.

Also, while measurements and charts are helpful, I really enjoy your writing style and how you relate everything to the casual observer/listener. It really makes your reviews enjoyable and worth the read.

I'm glad you found the review helpful. After you've had the chance to break in and tune your LV12R be sure to come back and post thoughts.

Thank you. It's always nice to know the reviews are beneficial to people. They require a great deal of effort, so hearing they help is gratifying.

Yo JIM!!! Thanks for this review!!

I am a huge fan of these LV12r's!! I own two as I type and I got to say for the release sales price of $500 each I could not be happier!
These really made my sub sq much better as I knew I was missing something with my previous subs that I owned. Either way, no regrets and if anyone does decided to plunge and get these, give them time to break in. They really, really will open up and not just the SQ gets better (due to the servo sub), but the SPL on these are very accurate and tight!! My movie watching is so much more tame and in control.

Bravo!!

First impression - WOW.

Ran YPAO and tweaked a few things and not even broken in yet, it's amazing what a change there is with a good sub. The sub brings a presence to things that's just huge. My wife even commented on the movie I am playing with (Inception), "their voices sound like they are right here". I thought the system sounded good before, but now it's, well, to use the Rythmik word - "articulate". It's brought an immediate competence to the system.

OK, the train just went down the street - awesome!

Right now, I'm thinking money well spent. I am loving it. Will give it a run for awhile and retune in a bit.

A really nice review. I like the style you chose to present in... less geeky and more down to earth description based. After all anyone can go to the website if they wish to see more graphs and specs.


Okay so let me testify:
Yes, the Rythmik's Direct Servo application really does clean up the bass. I've had two F12s for just about 4 years now. They ooze quality in every way... both in build and sound and Brian's service to the customer, both before and after the sale, is legendary. He even helped me... encouraged me... to perform an optional mod a while back (sent me the resistors with instructions etc)... he is an EE. He's a honest business man and a knowledgeable guy who stands behind his product... seems to be fewer and fewer of those type around these days. Back when I purchased my first F12, I thought I was taking a gamble by not having heard a Rythmik before but from reading all the reviews I could find at the time I noticed no one had anything bad to say about Rythmiks so... I took the plunge. When I got it set up and properly integrated into my system, I took the time to carefully listen to music I was quite familiar with and I was simply amazed... so much so I turned around and ordered a second F12 the same day. I'd never heard bass so clean before... I'm not an SPL kinda guy, I'm a SQ-oriented guy that likes everything to sound as real as possible. However I will say that I find the strength of this Direct Servo application to be found mainly in the range below 60Hz and I believe Brian would also agree with me. Above 80Hz its contribution is not really noticeable over the non-servo competition. Eventually after trying a number of set-up iterations in my theater, I've settled on using the F12s as ULF units and I now use dedicated mid-bass units. For awhile now I've been a proponent of splitting up the traditional subwoofer bass frequency range in two to be delivered by units dedicated to each range... that's just me and with the ultra-clean sound of the Direct Servo in the lower freqs the Rythmiks are the natural choice.

The F12 is a sealed design but from what I've read about all of Brian's ported models, they appear to not differ in SQ from the sealed models. The only change I would make if I had it to do over again is I would have purchased the 15" instead. Brian had suggested from the outset that I wait for the F15s to arrive but at the time the wait was 3-4 months out and I simply couldn't have waited that long. I didn't know if a single 12" 300-watter could cut it in a 2100 cu-ft basement but I was willing to give it a try... as I've said, I'm not really an SPL kinda guy. We generally watch movies about 10dB below reference which is plenty loud really... I just really need to have everything sounding as authentic/accurate as possible. The single F12 was actually enough to pressurize my basement theater without compressing at the bottom end but I know from past experience that my room's acoustics really demanded two subs for better freq smoothing in the 80-30Hz range so that was really why I got the second one.

Usually whenever I hear some one knocking the Rythimk, its either an SPL guy (you know the kind that thinks a home subwoofer is supposed to sound like the one in his "boom-boom" ride... all SPL and no quality or depth) or someone who's never actually heard a Rythmik. You'll wanna take comments from those type guys with a grain of salt.

Thank you. I'm glad you found the review beneficial. From the very beginning I wanted to write in a manner that differed from what most others were doing, and that meant conversational as opposed to technical. I do try and present a balance, but I lean more towards descriptive accounts than objective ones. Thus far it has served me well, and the vast majority of comments have been positive, so I don't envision changing my style going forward.

Thanks Joe - I'm glad you enjoyed the review. And I'm happy the little OSD sub is still working good for you!

Hi,are there any companies making cabinets for subwoofers other than Parts Express. I am not very good at wood working but I can put a speaker together and stain it if need be. I see that Rythmic offers several subwoofer kit's but nothing about cabinet's. I wouldn't mind assembling 2 kit's or should I just keep saving my pennies and buy the finished rythmic product?

Here Is one. You will need to make a hole for the amp though: http://www.sonicelectronix.com/item_951_Single-12-Sealed-MDF-Subwoofer-Enclosure-Belva-MDFS12.html

There are several, but it would be better to start a new thread in the DIY section specifically to address your needs. This one is intended for all things directly associated to the LV12R .

THESE would also work with the Rythmik kits. The 2 cu.ft. for the 12" and the 3 or 4 cu. ft. for the 15". The 3 cu.ft. would model the Rythmik E15 while the 4 cu.ft. would model the F15/F15HP.

You can contact Erich directly about the dimensions for the cutouts - he's a fantastic person - and I believe the Rythmik drivers have very similar if not identical dimensions to the Dayton Titanic series. I would still double check though.

Edit: Sorry for clogging up your LV12 review thread Jim.

Thanks afterlife2 and TheLaw612 for quick response. Sorry theJman for clogging your thread. I'm thinking of a Rythmik 12 inch kit so thought it might be a good place to ask seeing you reviewed a 12 inch Rythmik. My apology.
