Lol, with a 10k budget, I would stay far away from Bestbuy. First of all, you will want multiple high output subs for a room like that. I think you'll also want high sensitivity speakers as well. JTR would be a great choice there. Some which look great in that vein are GedLee Nathans
and the Pi Fours with upgraded drivers
. Also the JBL LSR6332
, if their appearance isn't too utilitarian for you, those are $1600 each. They are THX pm3 approved, so they measure and perform superbly. Any of those would make for a terrific front stage. For the surrounds, consider the JBL 8320
. Nathans, JTRs, Pi Fours, or JBL LSRs with two 8320s for surrounds leaves you with roughly $5k for receiver and subs.
For the receiver, I would get a Denon 4311CI
, it will have plenty of amplification for those speakers, and it comes with Audyssey XT32 with the SubEQ, that makes is a piece of cake to setup dual subs.
That leaves you with about $3k for subs, with which I would go for two Rythmik FV15HP
s. Two Power Sound Audio XV30
s would also warrant consideration.
You ought to have a little bit left over for stuff like cables, for cables, get it from Bluejeans cables
. Do NOT get cables at BestBuy, the markup is insane and you will get ripped off.
