The VHD4.21 Active Subwoofer Module consists of two purpose designed 'Low Loss-Band Pass' enclosures, one Active and one Passive, with each enclosure containing two specific custom designed large format 21" woofers.
The Low Q design has been applied to attain the optimum Loudspeaker loading, enabling a high sensitivity of 109dB 1w/1m. The design of our unique and innovative new power management system enables the Active Power Amplifier to deliver peak output levels of 14kW, whilst operating at a modest constant consumption of 3.6 kW from a 16A circuit.
An impressive maximum 320V supplied (limited) peak to peak at 100A from the VHD4.21 Active Module represents a bullet- proof technology that has been fully developed and refined over 12 years of active operation in real life applications, providing maximum control over movement of the large mass of the speaker.
