HELIX IK W10 10inch DVC (Dual Voice Coil) Subwoofer


Sale price£154.99



Stunning bass performance out of compact dimensions 

With the new KW chassis, we’re expanding our IMPACT subwoofer lineup, offering powerful drivers for use in very compact enclosures. Especially when it comes to the most efficient usage of available space in the vehicle regarding an individual enclosure design, these woofers create completely new installation possibilities without ever compromising the acoustic performance.

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 – 2 x 2 or 1 x 2 Ohms

The chassis are available as 1 x 2 Ohms (SVC2) or 2 x 2 Ohms (DVC2) version. Thus, these subwoofers always offers the right solution for every amplifier configuration to get the maximum performance out of it – whether mono, 2-channel or even multi-channel amplifier. 

"All inclusive" for self-made enthusiasts

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.
