VA 500 – 500 Watt Subwoofer Amplifier | MK SOUND




This dedicated Class D power amp with high efficiency, cool running and low standby voltage consumption is a further development of the amplifiers built into the popular M&K Sound V Series subwoofers. The Class D switch mode power module is designed with effective power reserves to effortlessly deliver copious amounts of clean power to the IW28S in-wall sub for extraordinary, uncompromising handling of demanding deep bass transients.
The classic M&K analogue input board ensures soft clipping, dynamic driver control. Stereo inputs and line-level pass through connections provide valuable flexibility for system building and future expansion. For perfect sonic integration with any satellite system, VA500 incorporates adjustable gain control including a fixed level position for reference set-up




While other manufacturers were building audio dinosaurs in the form of coffin-sized boxes, M&K led the way into the future with the world’s first satellite/subwoofer system, David & Goliath in 1976. The following year, M&K Sound introduced the Volkswoofer, the world’s first subwoofer with a built-in, dedicated power amplifier. The journey began in 1973, when Walter Becker of Steely Dan commissioned M&K Sound to design a studio reference subwoofer and monitoring system for the Pretzel Logic LP mixing sessions. The result was the world’s first balanced dual-drive subwoofer and Pretzel Logic went on to become a million-selling Top Ten hit and one of Rolling Stone magazine’s 500 Greatest Albums of All Time. Today M&K Sound loudspeakers have been chosen for the development and demonstration of the groundbreaking Dolby Digital cinema and home surround format, for the first public demonstration of the high-resolution Blu-ray disc format, for sound production on Star Wars Episodes I-III and countless other award-winning music, film and TV productions. A Who’s Who of the professional audio world – film, music, mastering and broadcast studios – continue to entrust their livelihood to M&K Sound reference monitors and powered subwoofers. The industry now state that M&K Sound speakers are the best for cinema reproduction in home or commercial grade cinemas
