Do us and yourself a favor - boycott the subwoofer mentality.
Why do you think they were unheard of prior to 1982? Because musicians used to be intelligent and professional.
Subwoofers, by definition, are BELOW the audio hearing range of the human ear... and hence, are worthless for listening to. In fact, they only distort and ruin any music in the audible hearing range.
Subwoofers, I suppose, are for vibration/feeling.... but again, the ultra low frequencies require mega doses of energy output to move them, just shake the hell out of everything and cause people to HATE the intrusion by amatuers who think that that is something cool.
Can you just imagine Herbie Hancock or Oscar Peterson (Jazz), or Seely Dan's Fagen or Becker (Pop Rock), or Aretha Franklin, Whitney Houston, or Celine Dion (singers d' excellence), or even Rock heavyweights such as VH, Aerosmith, Led Zeppelin, or Boston, or any other defacto standard of musical art... having a noise making subwoofer in their mix? never.
