I have 2 of these. 1 I bought new the other I picked up used for $400. These can be had easily for < $500. I lived with 1 for 1.5 years, adding the second has really made the difference from a really good HT to an unbelievable HT experience. I'm not sure about using it for music as mine are dedicated to HT. I would say this sub's best quality is it's tight/quick bass, not boomy at all ( sealed cabinet design ).
I don't have experience with REL but did have at 1 time, an energy sub, a psb subsonic 6, the M&K is in a whole other league.
good luck.
