Sunfire HRS – 12




Sunfire HRS-12 Powered Subwoofer (Piano Gloss)


Sunfire HRS-12 Powered Subwoofer for home theatre systems. The big breakthrough features of this 12″ subwoofer are its uncanny 1000 Watt 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!

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.
