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.

ditto the rel stadiumII. if you are patient they do come up every now and then for around 1500. the best i've heard.
I have listened to ALOT of subs and I would STRONGLY recommend the Genesis 900. Its the most musical sub I have listened to. 500 watt amo w/ a 15in. metal driver. Class "A" in Stereophile for along time. But let youe ear be the judge but certainly listen to the 900 if you can find one. Good Luck!
