Pick your surround config.
Let's be honest, It all depends on your wife or girlfriend...
•In wall 5.1 system YES
The wife loves in-walls, hidden and go with most decor. I feel in-wall speakers have greatly improved with back boxes and other acoustic controls.
•Front towers or bookshelf 5.1 or 7.1 system YES
I would most like a front tower system, full size center and large on-wall surrounds.
•Soundbar with simulated surround plus a sub NO
Not a fan of the sound bar. I don’t think the simulated surround field has been perfected yet.
•Smallest possible on wall solution NO
Do not like on-walls for front speakers, and if I was going to do surround sound I would only use small on-wall system for a second room, like a den.
•Wireless surrounds or wireless system MAYBE
I just don’t trust the wireless systems yet, I believe the technology has to be improved.
•Other?
I would love a 7.2 system with tower fronts and room subwoofers and in-wall center and surrounds.
