What are the best subwoofers you have heard for music. Speed, Musicality and integration

I got a Talon subwoofer that is a passive version of the Talon Roc from my local HiFi shop. It cost me $500, but it was worth every penny. I would suggest any subwoofer that has the highest retail cost, but is the biggest value to you.

@ricksgiving i love having subs in my system.  Helps bottom end 

I like the extremely underrated Vandersteen subwoofer.

Don't you find your phrase about subs and bottom too trivial... Of course if you eat too much subs you'll get bigger bottom!
