Dedicated IW28S Subwoofer Amplifier • 500W Continuous Class D Power • 800W Peak Output • Variable Phase and Crossover • Three-Position Room EQ • Rack-Mount or Standalone Installation
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.

Technology & Design
High-Efficiency Class D Architecture — The switch-mode amplifier delivers substantial output while supporting cool operation and low standby power consumption.
Dynamic Headroom Control — A calibrated monitoring circuit helps prevent audible clipping while preserving the wide dynamic range of modern movie soundtracks and digital music.
Placement-Specific Equalization — The three-position EQ control adjusts the system’s low-frequency response for different wall and corner locations, helping produce more balanced bass in the room.
Expandable System Connectivity — Stereo RCA inputs accept line-level signals from a receiver or processor, while unaffected pass-through outputs make it possible to feed additional VA500 amplifiers in multi-subwoofer systems.
FAQ — M&K Sound VA500
Which subwoofer is the VA500 designed to power?
The VA500 is specifically designed to power one M&K Sound IW28S in-wall subwoofer. M&K Sound does not recommend using the standard VA500 with other speaker or subwoofer models.
Can one VA500 power two IW28S subwoofers?
No. Each IW28S presents a 4-ohm load and should be powered by its own VA500. The RCA pass-through outputs can feed the signal to additional VA500 amplifiers.
Can the VA500 be installed in an equipment rack?
Yes. The VA500 is one standard rack unit high and includes removable rack handles for installation in a 19-inch equipment rack.
Does the VA500 include automatic power-on?
Yes. The amplifier includes an automatic signal-sensing mode that places it in standby when no signal is present and turns it on when an audio signal is detected.
