M5-HPA High Pass Mono Block Amplifier with Black or Silver Faceplate

M5-HPA is a scaled down version of the M7-HPA. This product shares the sonic excellence of its larger sibling while offering variable high pass settings, buffered output and a smaller size. This product is compatible with every Vandersteen speaker.

Vandersteen Audio's liquid-cooled M7-HPA (High-Pass Amplifier) is the inspiration for this all solid-state version in a smaller package. The dramatic reduction in distortion realized by Vandersteen’s patented Perfect-Piston™ drivers (US patent #8320604) made it clear to Richard Vandersteen that the next frontier of speaker performance would only be achieved by designing a radical new state-of-the-art amplifier from the ground up and this is the result for owners of Quatros or Model 7's which are not played loudly or are in large spaces.

Vandersteen for years has employed amplifiers custom-tailored to each design in Vandersteen’s subwoofers and the equalized bass sections in its powered-bass loudspeakers in conjunction with passive 100Hz high-pass filters for the ultimate performance. When paired with a Vandersteen powered subwoofer and/or a powered-bass Vandersteen speaker the M5-HPA monoblock, a complete system is formed in which the amplification over the entire frequency range is driven by perfectly tailored amplification.

Richard Vandersteen is responsible for the M5-HPA’s overall design and architecture; the amplifier was developed and built in partnership between Vandersteen Audio and Dean Klinefelter, a talented designer and engineer in his own right.
