    The Secret Behind Monitor Audio'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.
