Helix IK W8 DVC2 Version
Rich bass out of compact dimensions
The chassis of the K subwoofer series can all be used in very compact enclosures in which they perform magnificently with exceptional bass performance. Especially when it comes to using the available space in the vehicle as good as possible due to an individual enclosure design, these woofers open up completely new possibilities for installation without making any acoustic compromises.
Clever down to the last detail
The extremely stiff cone made of hand-scooped paper fibers in connection with the heavy-duty driver system not only converts amplifier power easily and without compression effects into loads of sound pressure, but also scores sonically with subtle beats.
Flexible connection
Designed as a 1 x 2 Ohms (SVC2) or 2 x 2 Ohms (DVC2) variant, you can find the right low bass specialist for any amplifier configuration to get the maximum performance out of it.
“All inclusive” for the do-it-yourselfer
In addition, the solid protective grille and gasket are also included.
For optimal bass performance in DIY installations you can find recommendations for sealed and vented enclosures with all parameters such as net volume, port tuning frequency as well as DSP settings in our technical data sheet.
