HELIX K 8W
Rich deep bass from compact dimensions
The chassis of the K-Subwoofer series all allow the use in very compact housings in which they play grandiosely with extraordinary bass performance. Especially when it comes to making optimal use of the available space 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 combination with the heavy-duty drive system not only converts amplifier power casually and without compression effects into powerful sound pressure, but also scores points in terms of sound with subtle beats.
Maximum flexible connection - 2 x 2 or 1 x 2 ohm
The drivers of the K subwoofer series are available with 1 x 2 ohm voice coil (SVC2) or alternatively 2 x 2 ohm double voice coil (DVC2). So there is always the right woofer for every conceivable amplifier configuration - whether monoblock, two-channel power amplifier or multi-channel amplifier - in order to be able to get the maximum performance out of it.
"All inclusive" for the do-it-yourself
A solid protective grille and a cover ring are of course included in the scope of delivery.
For optimal bass performance with 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.
