Description
The Klipsch RSA-500 is a dedicated amplifier engineered to power passive subwoofers with commanding authority. Delivering 300 watts continuous at 8 Ω or 500 watts at 4 Ω, it produces articulate, distortion-free bass across home audio and theater applications. The unit features a precision low-pass crossover for seamless integration with your main speakers, plus a dedicated EQ switch optimized for Klipsch subwoofer models. Dual input options—line-level and speaker-level—accommodate various system configurations, while intelligent auto on/off sensing eliminates manual switching. Its solid construction, aluminum front panel, and included rack ears reflect professional-grade build quality suitable for custom installations. The RSA-500 transforms passive subwoofers into a commanding low-frequency foundation for any serious audio system.
