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:
Read more about Direct Servo in our technology section. View animation demonstrating how Direct Servo works HX1000XLR3 Amplifier and DS1820 Driver FV18 comes with a grille. The above photo is shown with grill taken off. It uses our new high power HX1000XLR3 servo amplifier and the standard metal cone DS1820 driver. DS1820 features anodized aluminum cone, a 3" voice coil, and 240 oz magnet. Its linear excursion range is +/- 20mm. The standard amplifier is HX1000XLR3 (with both RCA and XLR inputs). The quickguide of the HX1000 amplifier for vented subs can be found here . The FV18 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. Paper Cone vs Metal Cone and Independent Lab Test Results Standard FV18 version uses metal cone DS1820 for its stiffness and low distortion. The independent test lab site www.data-bass.com has published the max distortion numbers for our metal cone FV18 and F18. The F18 has lower distortion and yet more output than Velodyne DD18+ for 1/3 of the price. Paper cone like the one used in Velodyne DD18+ can be made lighter than metal cone and therefore improve outputs above 50hz by up to 3db with the sacrifice of slightly higher distortions. For those who are after the maximum headroom in HT application may consider the paper cone version FV18SW (with paper cone SW1825). The order links are towards the bottom of this page.
