Re: Rythmik LV12R Subwoofer Discussion Thread

Jim, I know you really like the LVR-12. The other two well thought of subs at this price point are the HSU VTF2MK4 and the SVS PB1000. Since you also reviewed the SVS, could you offer any comments on how the LVR12 compared in your home and system to the SVS PB1000 with respect to musicality, deep bass extension and volume. Thanks....

Re: Rythmik LV12R Subwoofer Discussion Thread

I would have to give the edge to the LV-12R in all of the areas you mentioned. At $500 the PB-1000 is almost impossible to beat - especially given SVS's unique Bill Of Rights - but for volume, depth and musical ability I would personally take the Rythmik. The size is concerning, because it's not small, but for me that would be the biggest (no pun intended) drawback.

If you take yourself too seriously, expect me to do the exact opposite

Re: Rythmik LV12R Subwoofer Discussion Thread

Jim....thanks for the quick response.... In my case, I'm more interested in music then HT and my mains are the Tekton Lores which are about -3db around 35hz. The LV12R is physically about as large as I would want to go...smaller would be ok.

Im running Tekton Lores through a Parasound 2100 and Crown XLS2000( which has high pass and low pass filter capability) so, I would either cross at 50 or 60....or maybe even run the Lores full range.

Trying to read between the lines, am I also correct in surmising that you would give a slight edge to the LV12R over the Atlantic 444SB. Or might there even be something else I've missed and should consider?

Lv12r- Im running two of them. Compared to my REL T1, The LV12's are much tighter in sound. I purchased two for movies. I like the balanced sound two subs provide over one sub. Rythmic makes really great subs.

Re: Rythmik LV12R Subwoofer Discussion Thread

Jim (or anyone else who may have input),

I've spent many hours the past several days looking at different subs, many times feeling like I've found the one only to find something else that made me change me mind. Perfect example, Def Tech Supercubes, which looked great and have good reviews and I was about to pull the trigger on until I realized they don't do well below 30Hz, something that is hidden by the fact they don't publish full specs. While there's not much on the LV12R since it's so new, I have to say your review and positive comments on its predecessor and Rythmik in general really have me leaning toward it. I do have some concerns though and want to be sure I make the best purchase I can for the money.

My situation is as follows: My living room is open to the kitchen and dining room, as well as a double-wide stairway (split-level house, stairs go halfway down, turn 180 degrees, and go the rest of the way down) and a hallway. To make matters worse, the ceiling is vaulted. Not counting the hallway or the space down the stairs, which are separated from the living room by a half-height wall between them and the couch, the living/dining room and kitchen are ~8,000+ cubic feet. What I'm looking for is a sub that will provide deep bass primarily for movies/TV (and I watch a lot of sci-fi, fantasy, action, etc). I want it to sound and feel great. Music isn't very important to me, I'm not that picky, though of course I do want it to sound good. I, like you, prefer quality to quantity. Currently I'm using an Onkyo TX-SR607 to run Polk Audio RM6750 speakers with the included subwoofer. Because of this, pretty much any of the subs I'm looking at will be a huge step up, so ultimately I'm sure I'd be happy with any of them. Still, I'd obviously rather get the best for a given amount of money.

Here are the subs I'm considering:

Rythmik LV12R: $589
SVS PB12-NSD: $769
Hsu VTF-3 MK4: $750 (sale, reg $800)

I don't have a set budget. I'd like to not spend a fortune, and ideally keep it to the price range of the above, but am not totally against going outside of it. A big factor for me is the size: I don't want a massive box taking up a lot of space, and the larger it is, the less likely I will be able to position it perfectly, so while it would probably be ideal for me I'm not interested in a 15" or dual box or anything like that. I may after some time add a second one, though. Speaking of which, how important is it for them to both be the same (brand, model)? I'm thinking of maybe one of the compact SVS subs for the second one as that may be all I'd have room for.

Obviously the Rythmik is by far the cheapest option of the three, so I'm wondering how the performance compares. If it's similar, the Rythmik is a no-brainer, so my question is are they close or do one or both of the others outperform it by more than a small margin making it worth the extra cost? And do you think I would be happy with them considering my situation? Finally, how important is it to have ~1' of space between the back of the Rythmik and the wall, and could it be turned 90 degrees instead?

Re: Rythmik LV12R Subwoofer Discussion Thread

I spent many hours over 1 1/2 months looking at the $500-800 range in subs, back in May.

I have a home setup that is somewhat similar to yours - the system is against a wall, and the half cathedral ceiling goes up and away from that wall. It also opens to a dining area at the far end. It also has a hallway branching away - that includes the continued high ceiling. It's an acoustic mess.

I don't know the cubic volume, I didn't use it as a consideration.

I considered the following subs:

SVS PB12-NSD
HSU VTF-3 MK4
Outlaw LFM-1EX
Rythmik LV-12R
HSU VTF-2 MK4
SVS PB-1000

Despite my budget, I don't believe in filling it just because I can. I really wanted to feel good about my choice.

After a LONG period of consideration, I chose the LV12R on its specs, reviews and the servo technology. Its promise of good musicality and good HT performance was a good part of it too, and I feel its very true. I am totally happy with it.

The Rythmik has tons of great bass for home theater - I love it. Before this I had a little 10" BIC sub that burned up its amp. On retuning the system (Yamaha RX-V663), the sound really came alive. The much flatter and lower response of the Rythmik actually improved the sound of the entire system (any good sub would have), and it contributes to my level of sound happiness with the Rythmik.

I did not feel then, nor do I feel now that I went with a lesser sub by choosing the Rythmik. It's a totally great speaker and I would choose it again. And it only helps that it's cheaper than the rest!

Good luck in your quest!

An aside - I don't feel the need for a second sub (the space I have would make that a challenge anyway!) - this thing puts out more than enough for me!

Re: Rythmik LV12R Subwoofer Discussion Thread

Thanks for the response hemingray. I posted the same question on avsforum and everyone there is telling me I need to go to a 15" minimally and two 15" subs ideally. While I'm sure I do to get maximum effect, I'm just not sure if I personally need that. I'd hate to get a single 12" sub and find it lacking, but then I'd also hate to spend over twice as much, have two big boxes taking up space, and find it to be overkill. I'm really torn. I'm kind of leaning toward the PSA XV15 right now, and they even discount if you get two. I think I'm going to need to call the various companies and get their input.

I have a couple other questions to add: It's been made clear to me over at avs that mixing different brand subs is a bad idea, but what about different models from the same manufacturer? Also, since two subs apparently have 4x the output of 1, it would seem two 12" ones should be plenty, even for my cubic footage, and 15" unnecessary. Is this correct, or is my logic flawed? Of course, I realize it's all relative as well, as everybody's expectations are different. My final question is since I watch most of my content from Netflix, Hulu, and mp4 rips of my movies/tv shows, and therefore the audio is compressed and likely lacking much of the LFE content of a blu-ray, would I be wasting my money on a high-end sub setup?

Re: Rythmik LV12R Subwoofer Discussion Thread

I would not gauge the quality of the LV12r buy the price. Its helps with the purchase. They far exceed their price in quality.

I also own a F12 from Rythmik. It has more options than The Lv12r. It does movies really good but you have to watch your set up. Its a sealed system and will bottom out sooner. As i found out on Star Wars III. I use the F12 only for music only now.

The 2 LV12r's give me more dynamics and slam. From everything i have read, ported subs do this better for HT. But The LV12r never gets muddy or boomy. Im still learning how to set them up. So far my findings are, They sound tight, dynamic and easy to blend with my mains.
Compared to my 1000 dollar REL T1. The LV12r wipes the floor with it. (I compared them 1 on 1, i just received my second LV12R this week, Thanks Ascend Audio) The T1 sounded dull, muddy and really hard to blend in.

Just my .2 cents.

That's a bit more difficult to answer because the 444SB turned out to be a very impressive subwoofer for music. How large is your room? The output potential of the Rythmik exceeds the 444SB - as does the overall depth - but depending upon your room size and musical preferences those qualities may be of less concern.

Since you're starting to look in the $1000 range perhaps the Rythmik F15 or E15HP might be more to your liking. Both are close in price to the 444SB, but will offer more depth and output then the AT sub could provide.

You can take solace in the fact that what you're experiencing is not at all uncommon; the more you learn the more you realize there is to learn. It's the nature of the beast...

Your budget, requirements and environment are at odds with each other; there is simply no way a single 12" subwoofer will be able to handle that volume of space. A pair might get you to a usable level, but a single unit will be rendered mute unfortunately. Since your main objective is "a sub that will provide deep bass primarily for movies/TV" you're looking at a minimum of two 15" subwoofers, but realistically a pair of 18" is probably going to be required I'm afraid. Large space = large subwoofers, which is an immutable law of physics. I honestly don't envision how you'll be able to achieve your primary goal given those circumstances. You may have to re-think this before proceeding.
