I thought this was a interesting read about placing speakers close to the wall.
It is interesting indeed, but still just one guys observations. Couple things I got, were that he was interested in using monitors and mixing, and that all the different answers he got were from different speaker manufacturers. Also one noted a compensation switch. I’m sure that just rolls off the the low end earlier depending on how close to the walls or corner the speakers were.
As usual, it depends. That’s the mantra for all speaker placement. When I mentioned that, i wasn’t saying that as a be all end all factor. Only that on a(holding up air quotes lol) “serious” 2ch rig, they’re usually out in the room a few feet, and away from walls to try and reduce the rooms influence as much as possible. And yes it seems you are possibly trying to stuff too many things into one place.
As for using the other system for music. It’s difficult to get a real feel for the space from a sideways picture, but if it were mine, I’d try a couple things. First, I might try and get those mains a little closer to the display. From the pic angle, it looks like you could benefit for 2ch as you mentioned soundstage/imaging problems from being too far apart. Also, it could help with off screen panning with movies. Ime speakers too far off screen will make pans teleport from the side of the screen to well past where you’d expect them to go. If there’s room, “I” would put the sub in the corner, remove the acoustic panels and scoot the mains in. See what it sounds like. Heck, maybe try the NHT’s as mains too, cause why not?
Also(going off memory still) it looks like the center could come either all the way forward to the edge of the stand, or up in front of the tv. Although the tv might need a riser for that. That should help acoustically, and put the tweeters on the same(or closer) plane.
Ok, back to honey-do...
