if you want a good test track for subs then prodigy poison (album version) has tones right down to below 30hz...
and if you really want to see cones flapping get a hold of the single and play the second track rat poison.
the extreme LF at the end of the track detached the surround of my dads woofers on his rather expensive classic sansui sp-3500's 14" woofers - back before i knew what port loading was
glued my fingers to the surround with superglue fixing the surround back on...hey i was only 14!
worked tho...got em on right here as i write this
