Hey guys I decided on adding a subwoofer to my bandw 602's. I have always heard two subwoofers placed symmetrically in a room are far superior to one subwoofer. While on a budget, my question is whether buying two inexpensive subwoofers and placing them symetrically will sound better than buying one more expensive subwoofer by itself. I know with two subs I can better integrate the subs seamlessly to my stereo configuration.
