Sunfire Subwoofers

Sunfire HRS12 Subwoofer

The big breakthrough features of this 12″ 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!

The Most Performance You Can Buy for Less Than a Buck a Watt

You could certainly be forgiven for wanting an HRS subwoofer on its looks alone. With their compact, stunning, piano-like finished cabinets, the HRS Series subs make a design statement about themselves – and you. What’s more, beneath this beautiful exterior lies some of today’s most advanced audio science such as Sunfire’s High Back-emf driver technology. It produces massive amounts of low distortion bass from some of the smallest drivers around. In fact, the HRS-12 delivers output equal to the performance of most available 15” subwoofers, and does so with an unmatched visual finesse. The HRS-12 is ideal for larger rooms and dedicated home theater environments where the emphasis is on movies.
