Sunfire's HRSIW8 Subwoofer

The Stillbass technology, coupled with Sunfire’s high back-emf designed woofers, helps provide audiophile-grade bass from a subwoofer that retrofits into a standard 16-inch on-center stud bay.

According to Sunfire general manager Mark Weisenberg, “Everyday, the engineers and designers at Sunfire are developing new ways to deliver what homeowners want from their home entertainment experience; dynamic, accurate bass without donating large amounts of space in the process. We have accomplished that with the HRSIW8. Combining our legacy technologies with our latest thinking in subwoofer power and control, the HRSIW8 is simple to install. Setup is straightforward using Sunfire’s digital amplifier platform, which includes a wide array of optional adjustments for maximum performance. Now our dealers will be able to specify a budget conscious, high performance in-wall subwoofer that delivers on our brand promise.”

The HRSIW8 features two custom-designed 8-inch long-throw woofers using ultra low mass fiberglass cones in a sealed cabinet and only requires a wall cutout of 10.6-inches wide by 23.5-inches high. With six built-in dog-toggle style wall clamps, it is an appropriate solution for both retrofits and new construction jobs, easily fitting in any standard 16-inch on-center stud bay. A wire channel is provided on the rear of the enclosure to avoid pinching the wire between the enclosure and the back of the drywall inside the opening. Removable magnetic grilles and a cutout template for easy installation are provided.

The HRSIW8’s external rack-mount amplifier is an evolution of the Sunfire digital amplifier used in the company’s SDS subwoofer line. Using Sunfire’s frequency filtration design (FFD) for high fidelity bass, the amp delivers 520W of power with near zero distortion. A wide range of filtering adjustments are included, as well as DSP with room equalization and a remote control that provides one-touch access to preset equalizer modes.

The HRSIW8 has an MSRP of $1,700 and features a frequency response of 33Hz-150Hz, maximum output of 106dB, balanced and unbalanced line level inputs, gold plated speaker terminals and adjustable high-pass and low pass filters.
