I need some help folks. I have Polk RTIA3's and CSiA6 for front left/Center/Right. The wife now says no more speakers unless they are hidden so I am left with doing in-ceiling speakers for Right/Left surrounds and I am debating if I should even add the Left/Right Rears for 7.1 at all anymore.
Should I just do 5.1 with in-ceiling surrounds and call it a day or plan for the additional 2 rears? Attaching a layout of the room, the Red circles are possible locations for the speakers. Also I would be using Polk speakers (not sure which ones yet, suggestions appreciated)
If I was to do the rear ceilings as indicated in the first picture, they would be about 40 inches behind the couch. Do you think thats enough separation to be be of any value? I am of the opinion that it may be too close.
I have the cherry rti a3s as well, and love em!
I might get told I'm wrong, but 40in behind the couch should be enough, but I'd move the surrounds forward some to get better separation. I had a similar issue at my last house, and I could hear the rears just fine, even though most of my input videos were 5.1. My receiver would matrix then up to 7.1, and it was badass, especially on the Star Trek reboot, and games like GTA.
How far back in the corners should the surrounds go? I was thinking of running them a few feet to the rear and on the left/right of the couch. Would it be better to place them as far to the rear corners of the room as possible? I also went with the Polk 70-RT. They come in Tuesday, Can't wait!
From my experience the surrounds should go directly to the sides (at 90 degrees) and with the the back speakers it depends on how much room you have behind you. Back speakers that are further away can be separated more (like the Dolby suggested setup). But if they are not far enough away (like mine that are only a couple of feet behind) I like the way they sounded when putting them closer together (like the THX suggested setup).
All 4 of my rear speakers are in-wall and I am very happy with the surround effect that I get with them. Don't think that all in-wall speakers are created equal - if you get some with a "back box" or built-in speaker enclosure so that the sound doesn't bounce around inside the walls / ceiling they can sound very good.
My surrounds are in the ceiling at 90 degrees about 5 feet to each side and the rears are in wall above the listening position only a couple of feet apart. I had to make compromises like you, but I experimented with placement before cutting holes and I am happy with the result. I chose bipole speakers to spread the sound but I have no way of knowing how much difference that made.
