Vandersteen Audio's liquid-cooled M7-HPA (High-Pass Amplifier) is the revolutionary next step in power amplifier design and loudspeaker performance. The dramatic reduction in distortion realized by VandersteenÂs patented Perfect-Pistonâ¢ 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, exclusively for systems employing Vandersteen's time- and phase-correct powered subwoofers and/or powered-bass loudspeaker systems.
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.
