Sovereign Bass Performance from Compact Dimensions
The IMPACT subwoofer line, with its new KW single drivers, offers powerful bass solutions for use in very compact enclosures. Especially when it comes to optimally utilizing the available space in the vehicle through a custom subwoofer enclosure design, these woofers open up entirely new possibilities without having to make any acoustic compromises.
Clever Down to the Last Detail
The extremely rigid diaphragm made of hand-crafted paper fibers, in conjunction with the high-performance drive system, not only effortlessly converts amplifier power into powerful sound pressure without compression effects, but also delivers equally impressive sound with subtle beats.
Flexible Connection – 2 x 2 or 1 x 2 Ohms
The drivers are available as either a 1 x 2 Ohm (SVC2) or 2 x 2 Ohm (DVC2) variant. Thus, for every conceivable amplifier configuration – whether monoblock, two-channel power amplifier, or multi-channel amplifier – there is always a suitable woofer to extract maximum performance. "All-inclusive" for self-made enthusiasts. A solid protective grille and a cover ring are, of course, included in the scope of delivery. For optimal bass performance in DIY installations, our technical data sheet provides recommendations for sealed and bass-reflex enclosures with all parameters such as net volume, port tuning frequency, and DSP settings.
