Hey guys,

This Friday I'm going to go to my brother-in-law's place and will help him think up a home theater system. Apparently his house is prewired for surround sound and his media room is in the basement and is perfectly light-controlled, with dark red walls. The previous owner had a projector but I don't know what the setup was like.

Question - I was going to go along the lines of something like this:

Two 12-inch towers for the fronts:

Center channel:
https://amzn.to/2PHO7BA

Two rears:

Two subs:

Driving the show would be the following setup:
Preamp - http://www.outlawaudio.com/products/975.html
Amp - http://www.outlawaudio.com/products/5000.html

Thoughts? Please be nice - it's my first time doing something like this. Wink Seriously - I would love some opinions on what would constitute a good audio system.

For the projector, I plan on steering him to an entry-level JVC projector (RS-4x0). I'm not sure about room dimensions yet. I'll be taking measurements on Friday.

I haven't dealt with Cerwin in decades, but generally speaking, they are bass heavy (a good thing), LOUD! , efficient, but not accurate. That's about all I can tell you about the stuff from the 80s and 90s. The Jr Earthquakes from the mid 80s are still amazing folded horns.

Thanks for this. I'll continue to do my research but this may be right up his alley, as he's not an audio guy and only really wants his system to be loud and thunderous, without any distortion. He wants to bring the roof down. Smile

Wink if this is primarily a theater room those speakers will fill the bill at a great price.. that amp has the potential to damage the speakers at max power. how do you plan to connect the second sub?

The room is prewired for speakers. I haven't thought about how the subs will be connected. The room is a bit... Odd too. So the wall where the screen will go is massive - 192 inches wide. But the outlet and hdmi cable on the ceiling drop is only 12 feet away from the wall. I was hoping to recommend an RS-420 for them, but they'd essentially be maxing out the zoom to fit a 120 inch screen (which is what I was wanting to get). Honestly, that wall is so big we could go bigger but we don't have the throw distance for it.

Pretty lame design, if you ask me. We do have some play room (I can bring the projector back, but it will look a little weird) so we'll see. The room can be totally blacked so it would be a shame not to have a high-contrast projector.

Okay, so for audio we may be taking it down a notch.

Amp driving the show:

Front speakers:

Center and rear are the same as before

XLS-6C for center and XLS-6 for rear.

And for the subwoofer, we may just start with the XLS-15 inch subby. What do you guys think about that audio setup? I don't have the actual room measurements on me, so if you need me to get that I can get them.

All good. Asking opinions other than overall quality about matching speakers to amps doesn't really work online, as the room acoustics are going to affect the best (and worst) speakers more than an amp will.

Should sound good though. Me, I never use receiver's internal amps, I use the preamp outputs running to independent power amps. I love overkill though! Very Happy

Yeah, his room is a little "lively". I'm hoping that some furniture and the velvet surrounding the screen will dampen some of the reflections though. Thanks for the input. We may just start with the receiver and front two speakers and get a feel for the room. And then maybe add the other speakers later. Or if we don't like the sound, we return the speakers. I think Amazon has a pretty generous return policy.

Might want to consider making some sound panels. Just build a frame out of 1x4's, put 2" fiberglass panels in the front 2" (with 2" of empty space against the wall), cover with speaker grille cloth. That will absorb a ton of high freqs. There are different classes (different densities) of Owens Corning fiberglass that absorb different levels of sound.

In this thread I posted a pic of the two side-wall traps I built (roughly 2.5'x2.5'). I also built big bass traps in the front corners, about 4'x8' of 2" OC705 across the corners. In this pic you can see the two bass traps in the corner, another panel under the screen, and you can just see the tips of the side-wall panels.

What Gary said. I built 2'x 4' frames out of 1 x 1 wood, braced it in the middle, covered it in black microfibre material, and put Roxul insulation behind 1/2 the panels. My room had an annoying slapback reverb that only I could hear between the front and back walls (22' or so distance). We put the frames over the entire ceiling, covering the white paint, and all around the screen. The difference was remarkable. The room is DEAD! Improved the bass dramatically as well.

Yeah, that's what's *supposed* to happen. Didn't seem to do all that great in mine. I was really hoping for improved speech intelligibility, but it didn't seem to help much. And the room is still fairly live -- a handclap takes at least half a second to die down. Mostly off the side walls, I think, even with the panels there. Pretty ridiculous echo for such a small room, about 12x14. Guess I should have covered the ceiling like you did. I'm sure that's where a lot of your benefit came from.
