Helix K8W
HELIX K 8W
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 well as possible due to an individual enclosure design, these woofers open up entirely new possibilities for installation without making any acoustic compromises.
Clever down to the last detail
The highly 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.
Maximum flexible connection – 2 x 2 or 1 x 2 Ohms
The chassis of the K-Subwoofer series are available with 1 x 2 Ohms single voice coil (SVC2) or, alternatively, 2 x 2 Ohms dual voice coil (DVC2). Thus, these subwoofers always offer the right solution for every amplifier configuration to get the maximum performance – whether mono, 2-channel, or even multi-channel amplifier.
"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, and DSP settings, in our technical data sheet.
