Wiring wizard & port computer

Use our wiring wizard for simple wiring of speakers and subwoofers! The correct connection is important for your amplifier! Low-impedance operation can damage the amplifier! The data sheet shows you which connection the respective amplifier is designed for!

Our port calculator shows you which tuning your enclosure has! The net volume is always particularly important here; calculate the pure chamber of the subwoofer beforehand to arrive at the correct result. The net volume is calculated minus all displacements and is important when designing the enclosure.

HELIX IK S8

Flat design - deep bass
With the HELIX IK S subwoofers, the realization of particularly flat and compact enclosure designs is no longer a problem. The extremely shallow installation depth opens up new installation possibilities without any acoustic compromises. But above all, thanks to the use of large voice coils and the low resonance frequency, the HELIX IK S series delivers an absolutely superior bass performance that is in no way inferior to larger woofers.

Attention to detail and clearly thought out
The extremely torsion-resistant sandwich paper cone in combination with our heavy-duty drive system converts amplifier power into powerful sound pressure in no time at all without compression effects, but also demonstrates sensitivity with subtle beats.
A special highlight: the magnet system has a threaded hole on the back, allowing the woofer to be screwed to the rear panel of the cabinet. As every millimetre of depth counts in flat designs, this effectively reduces cabinet vibrations even with thin walls.

Flexible connection
The 1 x 2 Ohm (SVC2) or 2 x 2 Ohm (DVC2) design means that the right low bass specialist can be found for every amplifier configuration to get the maximum performance out of it.

"All inclusive" for self-made enthusiasts
In addition to the high-quality housing connection terminal with gold-plated screw connections, a solid protective grille and a cover ring are also included in the scope of delivery. For optimum bass performance in DIY installations, our technical data sheet includes recommendations for closed and bass reflex enclosures with all parameters such as net volume, tunnel tuning frequency or DSP settings.
