Hey everyone, newcomer to this forum, please be nice Currently I have 2 Energy RC-70s for my side, Polk Audio CS10 Centre Infinity Primus P143 rears and 2 subs split line ( not sure if this is a wise Idea, I do not have a 7.2 reciever ) The subs are Precision Acoustic PA12XS 200Watt 12" and an Infinity PS38 150Watt 10" Im really happy with side and centre speakers, the infinity rears are pretty clean as well. Im just not sure what i should get for side surrounds, and I would like advice on a more powerful Sub, looking for a 400Watt. My reciever is a DENON AVR-791 Something the way i have this set up just doesnt sound right. thanks for any advice! cheers!
