Sunfire HRS-10

I am selling this sub-woofer because I have recently upgraded my whole system and replaced this unit in the process. I was using this sub with a Rotel receiver and Totem floor-standing speakers, which are also for sale:  
Asking $400/OBO.  I do not have original box/packaging but will work with UPS/FedEX, etc. to pack securely to ship.

Sunfire HRS10

The big breakthrough features of this 10" subwoofer are its uncanny 1,000W Tracking Downconverter amplifier, and its long throw, High Back-emf woofer. These powerful forces combine to produce as much bass as several 15 inch drivers mounted in a cabinet the size of a small refrigerator!

10 Inches. 1000 Watts. Countless Hours of Enjoyment.

If your subwoofer puts out less than 1000 Watts, it’s not an HRS Series subwoofer. All HRS subwoofers produce this prodigious sound in a cabinet no larger than the size of your monitor. If that’s still not enough, the amplifier in all three HRS models incorporates Sunfire’s unique Tracking Downconverter™ technology. Remarkably, this amp design remains incredibly cool while delivering up to 50% more voltage than our competitor’s designs. More voltage means more control of the subwoofer itself. And more control means deeper, more accurate bass, something you’ll truly appreciate every time you listen to your favorite music and movies. For medium-sized and multi-purpose rooms, where both music and movies are just what the doctor ordered, there’s no better choice than the HRS-10.
