Just putting a new sub through it's paces. Movie LFE and artificial sweeps/tones aside, here are some musical tracks I've noticed have explicit, non-percussive, liver wobbling content... Basement Jaxx - U Can't Stop Me Avril Lavigne - Sk8ter Boi (1:51 is a very harsh sub test!!!) Moloko - Absent Minded Friends Royksopp - Poor Leno (intro) Jennifer Lopez - Jenny From The Block (yuck) Destiny's Child - Bills, Bills, Bills Faithless - Baseball Cap That list is right on the periphery of my normal taste in music and is the result of a very quick flick through my mp3 playlist. Not too much rock/funk/jazz stuff goes that low, although I notice some orchestral pieces w/classical bass drum hits are decent (they have a more natural soundstage than the above too). Any more suggestions? Cheers, MuFu.
