First thing is there is another thread similar to this one, but I did not want to hijack his.
I currently have a 5.1 system and now have a Panny Blu-ray that does 7.1 analogs (which my Onkyo 703 has), so now I want to expand my system to handle the 7.1 audio. My room is roughly 17' wide by 22' deep.
Here is my system now:
Polk RTi8's - Fronts
Polk FXi3's - Surrounds
Polk CSi5 - Center
SVS 20-39PCI - Subwoofer
So what would I need to match my current setup?
