The Boston Acoustics VSi S8W2 Dual 8" In-Wall Subwoofer is designed for discreet installation in walls or ceilings. It has dual 8" woofers with Deep Channel Design technology to deliver more bass from less amplifier power. The die-cast woofers and baffles add rigidity and ensure precise alignment of driver components for unparalleled accuracy. A boundary compensation switch lets you precisely tailor the sound to counteract the effects of the subwoofer being placed too close or too far from a corner, allowing for optimal sound from any installation location. The VSi S8W2 has a reduced bezel design for seamless integration, a paintable surface to match your decor and a magnetic grille.
