Yup - 12" woofers. Equivalent in area to a 3-and-a-half foot driver. It... Moves air.
My wife is rapidly tiring of organ music.
Check these out for bass with a break from organ music:
Spiritchaser - Dead Can Dance
Flight of the Cosmic Hippo - Bela Fleck
Convergence -Malia and Boris Black
Graffiti Jazz - David Chesky on his new label The Audiophile Society
Eiji Oue, Minnesota Orchestra, Stravinsky, The Firebird Suite - Reference Recordings
Bassotronics - The Future is Bass
No 15Hz pedal tones but plenty of bass to play with
