Overview

FV25HP is our answer to the need for a high power home theatre solution that retains the dynamic and accurate bass that we have become known for. Correctly integrated, our vented subwoofers can achieve the tight bass normally associated with a sealed enclosure, yet with greater low frequency output. We recommend this subwoofer for systems in which home theatre has a high priority.

Direct Servo Technology

All our subwoofers use our patented Direct Servo technology. The servo enables precise control over the cone which is essential for tight, dynamic and accurate bass. It also counteracts many different driver non-linearities and allows us to use lighter drivers which avoid the need for excessive amounts of amplifier power.

Some of the benefits of Direct Servo include:

• Dramatic reduction of the re-radiation of bass from inside the box, which is commonly referred to as boxy bass.
• The effects of thermal compression are eliminated under normal operation
• Higher efficiency allowing output which would normally require a more powerful amplifier
• Deep bass extension can be achieved using a low mass driver with superior transient response
• Mechanical and thermal memory effects are reduced, further improving transient response
• The effective Q value is 0.1 resulting in much tighter and accurate bass than conventional designs

HX2000XLR3 Amplifier and Dual DS1520 Driver

FV25HP comes with a grille. The above photo is shown with grill taken off. It uses our new high power HX2000XLR3 servo amplifier and two DS1520 driver. DS1520 features anodized aluminum cone, a 3'' voice coil, and 200 oz magnet. Its linear excursion range has increased to +/- 20mm.

The standard amplifier is HX2000XLR3. The quickguide of the XLR3 amplifier for vented subs can be found here . The installation guide can be found here. The response curves with various extension frequency/damping combinations of both amplifiers can be found in our EQ page.

The sub comes with standard screw-in rubber feet. Chrome spike feet are sold separately.
