Kenwood SW201X
パワーバスリアクター(筒型サブウーファーシステム) — The Kenwood SW201X "Power Bass Reactor" is a self-contained, tube-shaped powered subwoofer — a 200mm long-throw woofer at one end of a sealed cylindrical enclosure, a matching 200mm passive radiator at the other, and a built-in amp driving the whole thing. The dual voice coil woofer is fed 240W (60W × 2Ω × 4, dual-coil drive), with a 3-step low-pass crossover (50/80/120Hz), a 0°/180° phase switch for dialling in cabin placement, and a bass boost switch. A wired remote handles level, crossover frequency, boost and the blue CFL illumination ring from the driver's seat. Accepts either RCA line-level or high-level speaker inputs, so it'll hook up to almost anything. A genuinely eye-catching, period "tune-up" subwoofer.
Harness Included.
