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?\nAlso(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.\nOk, back to honey-do...\n\nI used to have the ST4s as mains. Right now sit 10ft away from the TV and center, I have the front mains 15 feet apart. I thought for movies you have the mains 1.5 x your distance and for music you sit 1.5x the distance between your speakers. I could go back to the I had it as a equal triangle and just be happy. Just always wanted a music only 2 channel set up. I just don't have the right space available.\nAs for the center the tweeter is 29 inches off the ground and the fronts are 32 inches. I I go back to using the ST4s they are 30 inches off the ground. This is the NHT series that placed the tweeter under the woofer. Oh and the acoustic panels used to be behind the fronts to help with them being so close to the wall. If I go back to that I will also take my dipole rears down and use the SB3s and surrounds on the stands in the correct placement. As for the sub I might try it in the corner of I have room. It's a monster lol\nI'll have to wait and see what happens this weekend. I have a line on some NHT T5 towers, and a Anthem 2 channel amp. Just always wanted a set of T5 or T6 for some reason lol. It always nice to get another person's perspective. I wish I knew some local audio guys to get together with. Thanks goodness for great forums like this!
