The CA-200 subwoofer amplifier is an updated version of the once popular SA-150, the 200 Watt RMS CA-200 is an excellent alternative to the component-style SA-200 amplifier. It’s a little boxy, but the CA-200 provides strong and clean bass to any non-powered freestanding, in-wall, in-ceiling or in-floor subwoofer. The CA-200 has plenty of features and adjustments to help optimize any subwoofer installation. With either it’s pre-amp or 5-way binding post speaker level connections, the CA-200 can be quickly and easily connected to any stereo or multi-channel processor. The CA-200 even has a dedicated LFE input which bypasses the internal low-pass crossover when used with a surround processor’s bass management.
