The Dayton Audio SPA500 subwoofer amplifier is based on a state-of-the-art Class G circuit topology that combines the proven high power, high fidelity characteristics of a Class AB amplifier with a patented tracking down converter power supply to achieve an operating efficiency up to 86%. You get the efficiency of a Class D amplifier without compromising audio quality and reliability. The Class AB output stage provides the clean and low-distortion sound that audiophiles demand, without any of the instability problems that plague other high-efficiency amplifier designs. This American-designed and engineered amplifier uses patented circuitry that continuously tracks the input signal to modulate or control the voltage available to the output stage. This "tracking" capability delivers the exact amount of power based on demand instead of constantly keeping it in reserve, so the output stage only draws the amount of power that is required at any given time. Less energy is wasted as heat, and more power is available for the subwoofer driver. With its enhanced thermal management, the SPA500 is an upgrade over previous models—making it a nearly bulletproof amplifier choice for todays demanding HT audio and music playback applications. Cutout dimensions: 10" W x 10" H.
