In-wall rear surround recommendations

[William Lemmerhirt]

They sound great! Haha. I realize we're way off topic. Should I start a new thread?

Audyssey turns the surrounds up a little too loud, so I have to turn the levels down about 4dB to 5dB to get them to blend in better. Not sure why it's doing that.

Nah... Unless you want to.

The L22 has a small enough footprint that I could live with two of them if it comes to that. Dual 12's have 1.3 times the cone area of a single 15" and with only a 14"x16" footprint. If this is a viable option for me then it sounds like it is definitely worth trying. Also, only $800, which I like.

Ya I think that’s a great way to go with your floor space issue. They should give you a slight discount on 2nd one.

A timely post from Shady with some info that may or may not matter here.

2 HSU over 1 Rythmik

Just thought of this. SVS doesn't have speaker level connections, so that would not help me. I am using a Yamaha 2 channel amp. No sub out. The MartinLogan Dynamo and Paradigm Defiance sub apps have most of the same functionality of the SVS sub app, plus they speaker level inputs and ARC room...

He’s always seemed a little cool on Rythmik subs. (It may be as simple as many consumers thinking the servo technology somehow trumps the rest of the physics involved.) Regardless, I’ve not ever really heard any negatives about Rythmik. I think that there is a common level of performance among all the ID companies and the individual characteristics that really matter come down more to personal preference (extension vs mid bass output, connectivity options, eq options, etc).

This is my thinking. A competent, good performing sub is a good performing sub. I don't think a guy could really tell the difference just by listening if we're comparing like products.

I think he said Rythmik hasn’t let him test their subs so he is more comfortable recommending the particular subs that he has tested and measured.

I think he's just yearning for Hsu...

 

[snakeeyes]

Yearning for 10 subs like ADTG has...

Right, I keep forgetting about that. I could very well end up with a sub in the hall upstairs! If it's going to be tall, then I'd prefer a box shape and forward firing considering my flimsy floor. And the PC2000 has a rear facing port, which wouldn't be good because I would want the sub pretty close to the wall. So....what about the Rythmik L22? Two 12" servo subs in a sealed 14"x16"x28" tall enclosure: http://www.rythmikaudio.com/L22.html

As far as the rear facing port goes, it's a cylinder. Just turn it, lol.

Down firing on a flimsy floor could be a factor tho so I have to give you that one, tho there are ways around that too. A solid base for instance.

Yeah, but then the amp and wiring will be showing. The PC2000 really isn't appealing to me, so I'd to take that one off the list.

Is anyone emphatically against recommending the Ryhtmik L22 with the potential of getting a second one at some point? It won't be too overbearing from an aesthetics viewpoint, will give me more output than a single 15, and should hopefully blend in nicely with my Mythos Nine fronts.

I was getting ready to comment on that exact thing, Snake. To Shady's point, I think third party testing is really a necessity. It had a role in my choice of Subs, for certain. I'm still curious about Rythmik, but that element of uncertainty weighs.
Aside from some old tests by Ricci at Data-Bass, there just isn't a lot of extra info on those units. I've considered a DIY with one of their Aluminum drivers and higher level Amps. May still, but that's a ways off if I do. (By the numbers, they might be good candidates for a TL build!)

Well I know Peng measures his Rythmik E15 subs all the time. I wouldn’t worry about that model.

I have an Acura TL. You're saying I should put them in my trunk then?
Seriously though, what's a TL build?

It's one of my rabbit holes too. One of our members designed and built a magnificent system based on TL designs.

I thought it about time that I gave an account of a very busy time for us. We have worked very hard these last two months to get out of our home on Benedict Lake. The large workshop, the AV studio and the 4,500 Sq foot home had to be packed up and parts sold. We had an auction at the site on...

TL is for the rich. LOL.

I just noticed Rythmik has "dual opposing" subs, available in 12" and 15" sealed enclosures. I wonder if I were to locate one of these with the drivers firing left/right if it would have the same effect as having two separate subs on the left/right of the room. Or would it still act like a single sub/enclosure?

Just makes it a strong single sub. Not the same as 2 subs in different places in the room.

Makes sense. Just thought I'd throw it out there. I have to remind myself that bass is omni-directional so it doesn't make much difference which way the driver(s) are facing.

I also need to take into consideration that if I go with the L22 and decide to get a second, is four 12's going to be overkill? I'm thinking it will be. So this has me leaning towards two separate 15's again. Ugh! I'm going to mock up some cardboard box representations of the two subs and see which I can live with from a size perspective then make my decision I guess.

For that big of a space 4 12's will not be overkill.
