Hello everyone.

I am helping a friend put togather a dedicated HT room.
The room size is 23' long by 8.5 wide with a 7'ceiling.
The speakers he purchased were from Polk Audio.
Specifically the RTi A7's for mains, FXi A6 surrounds and the CSi A6 center.

He wants the ability to bluetooth his iPhone and have a receiver that allows duel subs.

Any advice for make and model as well as wattage for this 5.1 system is appreciated.

Thanks to all.
