Which sub is better for audio


I am looking to buy a sub to be used primarily for audio. My options are Sunfire true sub, HSU, and Bag End. I intend to spend no more than $1500. Your advice will be appreciated.

I am using a Bag End with Von Schweikert VR4 Gen II's. Seamless Extension.Magic Audio in Atlanta is the place to get one under 1k dropped shipped direct from Bag End.
Used several of the above subs. The best one on a dollar per unidistorted dB of output is the HSU1220HO. A real deal in audio and don't let anyone who has not auditioned one at home tell you other wise. Check Issue 15 of the Audio Critic assessment and measurements for the straight goods. The others are not as good as you may think (or their designers for that matter) Been there, done that, wasted a lot of money...
bsg, the hsu is a nice sub, and the only reasonably-priced (under $3k) unit i'd consider - if, that is, vmps weren't around... :>)

Auditioning a Rel is a must. Ther are downward firing and dont move as much air as some but they are seemless and produce an untouchable quality.
