A 520 Watt Vibration-Free Performance Statement Designed Exclusively for In-Wall Applications

Powerful. Thoughtful. Formidable. That best describes the new Sunfire In-Wall 8 Subwoofer System. Wrapped in a cabinet so thin and sophisticated that you can use every one of those Watts with virtually no mechanical vibration whatsoever. Bass performance that can play your movies, music and games with the kind of accurate reproduction that shows no favoritism. A ‘Credit Card’ Sized Remote Control with One-Button, Pre-Programmed Sound Modes is included.

What allows the Sunfire In-Wall 8 to rock your world without rocking your drywall and your family’s nerves along with it? It's an exclusive Sunfire technology called StillBass®. Originally designed for the unbridled power of the SubRosa, StillBass allows Sunfire to pack more power and performance into our In-Wall subwoofers than any of those so-called ‘competitive’ products. Now, since the bass is what makes the biggest difference in your music, movies and games— the In-Wall 8 System is a force you’ll delight reckoning with. Designed for easy retrofit mounting and the paintable, removable grill attaches flush with magnets.

The HRS-IW8 Amp boasts 520 Watts RMS of power, can drive two of the HRS-IW8 Cabinets and includes the science of Sunfire's Frequency Filtration Design (FFD) for detailed fidelity playback for all source content.
