The VS8 is a subwoofer that features an innovative design. The compactness, various mounting possibilities, and multiple wiring configurations make it a perfect addition to any stereo, home theater or even car audio system. The Dayton Audio VS8 subwoofer was engineered to accommodate the challenging space requirements of modern home audio installations. Despite its emphasis on compact size and flexible connectivity, the VS8"s designers maintained Dayton Audio"s typical commitment to faithful audio reproduction. A VS8 can be installed permanently in walls, floors, or ceilings, but is attractive enough to deploy in "opportunistic" locations like behind a sofa, beneath a table, or tucked into a corner. Performance-wise, an 8" long-throw dual voice coil driver and complex bass reflex design that utilizes a flared port produce much more bass than is expected typically from such a small loudspeaker enclosure. The Dayton Audio VS8 low-profile subwoofer is finished in a dark brushed aluminum-look vinyl wrap that complements any decor. IMPORTANT: This is a passive subwoofer, and requires an external amplifier connected to the unit to operate. Dayton Audio SA230 amplifier recommended.
