PSI Audio Sub A225-M Dual 10" Subwoofer

OVERVIEW

An exceptional piece of acoustic design, the A225-M sub-woofer/bass extension is equally suited to use as a mono sub-woofer in a surround sound application or as a bass extension in a stereo system. Designed to work in harmony with the A225-M Sub, all PSI Audio ‘A’ series speakers feature a frequency response roll-off function that, when combined with the A225-M Sub, extends the frequency range down to an incredible 24 Hz, whilst maintaining a flat response.

The powerful class G outputs feature PSI Audio‘s unique “AOI” output stages, giving the A225-M an unprecedented impulse behavior. Each driver and amplifier unit is secured by a protection circuit, which is monitored by a red LED on the front panel.

The electronics are housed in a unit mechanically isolated from the speaker cabinet to avoid resonance at high sound pressure levels. To provide stability and avoid cabinet resonance A225-M is built with a double-box design, combining two cabinets into a single beautifully finished unit.

What did Chris Athens have to say after choosing to purchase the A21 for his room?

The PSI A21 are fantastic near field / mid-field monitors.

Accurate without being clinical. "High Fidelity" without hype. Tons of power and headroom.

I got mine as a demo from Mr Dent at Zen Pro Audio and I never gave 'em back [sorry Warren].
