As far as I know, the 200 should have plenty of power to do a good job with the TN1220, which is a very nice sub. Be aware, however, that Hsu subs use equalization to achieve flat response to the nether regions. They offer a product to use with non-Hsu amplifiers. Check the Hsu website.

(The coming Outlaw sub looks pretty great, too, if you are inclined to wait.)
