Monitor Audio Radius 390 Walnut Powered Compact Subwoofer

The kind of bass you'll look forward to hearing I remember the day I added a high-performance subwoofer to my home theater system. The difference in the quality - and quantity - of bass over my previous model was immediate, and showed me just how much I'd been missing with my beloved sci-fi movies and music playlists. If you want a similar high-impact bass experience, consider Monitor Audio's Radius 390 powered subwoofer. This elegant and surprisingly compact sub delivers the kind of bass you'll look forward to hearing (and feeling) with your favorite movies, albums, TV shows, and video games. An attractive grille-less design adds to the visual pop of this high-quality subwoofer. The "secret sauce" behind Monitor's high-tech woofers The keys to the Radius 390's powerful performance are its brawny 220-watt Class D amplifier and advanced driver design. Housed inside the Radius 390's enclosure are twin, side-firing 10" woofers working in tandem - one powered and one passive. Each cone is made from a lightweight, ceramic-coated aluminum/magnesium alloy originally developed by the aerospace industry for jet engine components. This ultra-rigid material resists the bending and twisting that causes distortion, while allowing the use of thinner, lighter, and more responsive materials. The result is tight, fast, and tuneful bass with exceptionally high output levels. Attractive grille-less design Please note that this subwoofer does not come with grilles. Instead, it uses color-matching cones that complement the enclosure's attractive finish.
