hi, im thinking of upgrading my subwoofer cause my cheap onkyo sub is just too muddy sounding, its annoying. i plan on getting either a velodyne CHT-10 or CHT-8. my basement is real small. its 18 by 10. my fronts are Klipsch SB-3. Im thinking that the CHT-10's might be overkill. im not really sure if they match well with my fronts. any suggestions?
