SONANCE CABINET SUBWOOFERS
Introduction
Thank you for purchasing a Sonance Cabinet Subwoofer. When properly installed your new subwoofer will add a solid deep bass
foundation to all your audio/video entertainment. This manual will teach you all about your new subwoofer’s many
innovative features and will show you how to get the very best performance from it. Please read it thoroughly.
Since all Sonance Cabinet Subwoofers have identical installation requirements, the directions in this manual apply to each model in
the series. This manual covers these subwoofer models: Sub 12-250, Sub 10-150, Sub 8-100.
Design and Features
Your new Sonance Cabinet Subwoofer delivers powerful, low-distortion bass, and easily blends with your room’s décor. The anodized
aluminum woofer cone and heavily-braced sealed enclosure deliver room-shaking bass from a small cabinet that gives you many
installation options. The front-mounted controls and recessed amplifier panel let you tuck your subwoofer away under a shelf or install
it flush with a wall or cabinet front.
