Hi all, I am planning to buy a SVS subwoofer. Advice by Tom V was the 20-39 PCi. But there's this itch that I gotta scratch...and i am opting for the PC+. The option of tuning your subwoofer yourself is just to good to ignore. But now I have to choose between the 25-31 PC+ or the 20-39 PC+ If I choose the 20 PC+...am I overdoing it to much? Is there something like TO MUCH subbass? Hopefully you people can help me out.
