What's the best solution for surrounds in my new place? There's little distance between my viewing couch and rear wall so surround effects sound too directional, rather than ambient. The rears are on 100cm stands to add some height. I thought of wall mounting and aiming downwards, also looking much neater, but feel like they'd be too heavy for this? Things improved significantly when I pointed them straight ahead instead of towed in. I considered bouncing the sound off the rear wall, but that's an aesthetic compromise too far. Would dipoles or bipoles on the side wall work better? Or perhaps smaller satellite speakers mounted high up on the rear wall? With the latter I could also do 7.1 with two on the side walls.
