The M5-HPA is a solid-state design descended directly from the flagship monoblocks.
It will be substantially less expensive, but will offer an astonishing amount of the flagship's sonic magic. While the M7-HPA is designed specifically for Vandersteen's Model Seven Mk II speakers, the M5-HPA will work with a much wider variety of loudspeakers and Vandersteen powered subwoofers.
To accomplish this goal, while the M7-HPA's high-pass is fixed at 100Hz, the M5-HPA's internal high-pass filtering is adjustable to any of the following five settings: 20Hz, 40Hz, 80Hz, 100Hz, 200Hz.
Vandersteen for years has employed high-pass filtering with powered subwoofers for the ultimate in powered-bass performance. When paired with a Vandersteen powered-bass speaker like the Quatro Wood CT the M5-HPA forms a complete powered-bass speaker system in which the amplification is perfectly optimized over the entire frequency range.
Richard Vandersteen is responsible for the M5-HPA’s overall design and architecture; the amplifier was developed and is built in partnership between Vandersteen Audio and Dean Klinefelter, a talented designer and engineer in his own right.
Vandersteen powered-bass speaker systems are the ultimate expression of Richard Vandersteen’s philosophies on design and performance, formed over decades of industry-leading design & research & innovation.
