Flat dimensions – deep bass

The extremely low 84.5 mm installation depth opens up enclosure options that would not be possible with a conventional subwoofer, without making acoustic compromises. Large voice coils and a low resonant frequency ensure strong, deep bass performance from the compact IK S platform.

Smart down to the very last detail

A stiff sandwich paper cone and heavy-duty drive system convert amplifier power into high sound pressure with no compression effects, while retaining control on subtler material. The magnet system features a threaded hole on the rear, allowing the woofer to be bolted directly to the enclosure back panel — reducing enclosure vibrations even when walls are thin.

Flexible connection

Available as a 1 x 2 ohm (SVC2) or 2 x 2 ohm (DVC2) variant, the IK S series can be matched to a wide range of amplifier configurations for maximum output. Pairing with a Helix DSP Mini MK2 allows precise tuning to your chosen enclosure alignment.

"All inclusive" for self-build installations

The IK S10-DVC2 includes a gold-plated screw terminal, solid protective grille and gasket. Helix's technical data sheet provides sealed and vented enclosure recommendations including net volume, port tuning frequency and DSP settings.
