M&K Sound VA500 Subwoofer Amplifier
Dedicated High-Power Amplifier for the M&K Sound IW28S

The M&K Sound VA500 Subwoofer Amplifier is purpose-built to power the M&K Sound IW28S in-wall subwoofer. Its high-efficiency Class D power stage delivers 500 watts of continuous output and up to 800 watts of peak power into a 4-ohm load, giving the IW28S the control and dynamic headroom required for deep movie effects and accurate music reproduction.

A compact one-rack-unit chassis allows the VA500 to fit neatly into a centralized equipment rack, while removable rack handles and supplied feet support standalone placement. Adjustable volume, continuously variable phase, a variable low-pass crossover and three room-adaptation settings make it easier to integrate the subwoofer with the room, main speakers and listening position.
