Description
LFE meets accuracy and control
FV18 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 boxy sound reduction of the re-radiation of bass from inside the box
- 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 creep memory effects are reduced, further improving transient response
- The (temperature-independent) effective driver Q value is 0.1 resulting in much tighter and accurate bass than non-servo drivers with typical Q value of 0.3-0.5 (and even higher when voice coil becomes hot)
