Super Bass, which I gave away, and SuperBass 2 which I still have, are among the rare CDs that don't sound right with my single mono subwoofer located behind my left speaker.Bass at subwoofer frequencies is mono in almost all CDs (not that ears only 6" to 8" apart could hear any stereo effect with subwoofer bass wavelengths from 14 to 50 feet long).
The bass may be panned left or right in a recording but there is rarely any out-of-phase bass information on a two-channel CD.
Some surround sound videaos do have "stereo" bass sound effects.Bass harmonics above 80Hz. played by the satellite speakers will place the bass instrument image properly on the soundstage. That's why a mono subwoofer works well almost all the time.
The Superbass CDs are rare exceptions because they have different bass players on each channel. Summing these CDs to mono for a single subwoofer can change the sound versus using two subwoofers. Especially is the single subwoofer is not halfway between the speakers ... and even that doesn't work as well as "stereo" subwoofers for the SuperBass CDs.
I tested hundreds of CDs back in 2004 before I switched from using two 12" sub drivers ("stereo") to a single 15" dual voice coil sub driver (mono).
My Super Bass CDs, and a few techno bass CDs with different bass sound effects in each channel, were my only CDs of hundreds that didn't sound right with my off-center mono subwoofer.
