Sub A225-M

“The real trick is to simultaneously provide a pure neutral processed signal and bypass all the obstacles on the road to obtain it. PSI Audio staff challenged laws of physics and mechanical constraints. Engineers from the company PSI Audio mastered this art.”

Product Description

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.
