Flat dimensions - deep bass

With the shallow HELIX IK S subwoofers, the realization of particularly flat and compact enclosure designs shouldn't be a problem anymore. Its extremely low installation depth opens up new installation possibilities that do not require making any acoustic compromises at all. Additionally, thanks to the use of large voice coils and its low resonant frequency, the HELIX IK S series delivers an absolutely stunning bass performance, which is in no way inferior to larger dimensioned woofers.

Smart down to the very last detail

The enormously stiff sandwich paper cone in conjunction with our heavy-duty drive system easily converts amplifier power into powerful sound pressure without any compression effects, while simultaneously demonstrating finesse when it comes to more subtle beats. A special highlight: the magnet system has a threaded hole on the back and thus allows the woofer to be fixed to the back panel of the enclosure. Since every millimeter of depth counts in flat constructions, enclosure vibrations are effectively reduced - even with thin walls.

Flexible connection

Designed as a 1 x 2 Ohms (SVC2) or 2 x 2 Ohms (DVC2) variant, you can find the right low bass specialist for any amplifier configuration to get the maximum performance out of it.

"All inclusive" for self-made enthusiasts

In addition to the high-quality connection terminal with gold-plated screw terminals, a 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 or DSP settings in our technical data sheet.
