Sunfire HRSIW8 In Wall Subwoofer


In 1972, graduate student Bob Carver turned an ordinary classroom assignment into the beginning of the iconic brand of home audio products that is Carver Audio. That assignment - to build a machine that would simulate earthquakes - became the springboard for a four-decade run of innovative 'firsts' and 'onlys' that have continually raised the benchmark for the entire home audio industry. Headquartered in California, Core Brands is a division of the Nortek Technology Solutions Segment and combines the product and marketing strengths of ten iconic audio, power management and control brands. These include the ATON®, BlueBOLT®, ELAN®, Furman®, Niles®, Panamax®, Proficient®, SpeakerCraft®, Sunfire® and Xantech® brands. Core Brands has more than 190 years of combined experience in the residential, commercial and professional markets and over 4,300 direct customer accounts in multiple distribution channels in the United States and around the world.


Every Sunfire engineer knows that the way each individual frequency relates to another has a significant influence on the fidelity - or level of detail of the final performance. Sunfire's exclusive FFD Technology is what makes the In Wall 8 Amplifier the perfect soul mate for the In Wall 8 Subwoofer’s prodigious bass capabilities.

StillBass® - When you eliminate the mechanical vibrations normally inherent with all in-wall subwoofers, you have just one brand remaining: Sunfire. That’s because Sunfire invented a technology called StillBass. StillBass cancels, or even eliminates those mechanical noises from Sunfire’s In Wall subs so that you’re free to turn the sound up and enjoy the incredible bass experience you’ve always craved. Clean, crisp and accurate bass that will give your music, movies and games a level of detail you won’t get in any other product of its kind.

Sunfire has created a system where the subwoofer, the amplifier and even the remote control are purpose-built to work together as just that - a system. Each component complements the other to provide what they believe are the best performance characteristics possible. And the best performance is what you think it is - not what anyone else does. Which is why the Science of Sunfire lets you dial in the sound that’s just right.
