HELIX IK W12
Superb bass performance from compact dimensions
With the new KW single chassis, the IMPACT subwoofer line offers powerful bass suppliers for use in very compact housings. Especially when it comes to making the most of the space available in the vehicle with an individual subwoofer housing shape, these woofers open up completely new possibilities without having to make any acoustic compromises.
Clever down to the last detail
The extremely hard membrane made of hand-made paper fibers in conjunction with the heavy-duty drive system not only converts amplifier power into powerful sound pressure easily and without compression effects, but also scores points in terms of sound with subtle beats.
Flexible connection - 2 x 2 or 1 x 2 Ohm
The chassis are available as a 1 x 2 Ohm (SVC2) or 2 x 2 Ohm (DVC2) variant. This means that for every conceivable amplifier configuration - whether monoblock, two-channel power amplifier or multi-channel amplifier - there is always the right woofer to get the maximum performance out of it.
"All inclusive" 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 contains recommendations for closed and bass reflex enclosures with all parameters such as net volume, tunnel tuning frequency and DSP settings.
Features
- 2 x 2 Ohm double voice coil for flexible System configurations
- Extremely torsion-resistant, hand-made paper membrane for exceptional impulse fidelity
- Double ventilation of the voice coil for minimal compression effects and high resilience
- Long-stroke rubber surround for maximum mechanical resilience
- Solid pressure terminals
- Powerful magnet system optimized for compact housings
- Robust magnet cover with HELIX lettering to protect the magnet
- Grille and cover ring included in delivery
