Helix K 10S - 25cm Flat

HELIX K 10S

✓ Flat design - rich deep bass

The K 10S is the problem solver par excellence when it comes to the realization of particularly flat and compact housing designs. The extremely low installation depth of this woofer opens up completely new installation options without having to make any acoustic compromises.

Thanks to its large double voice coil and low resonant frequency, the K 10S does not need to hide behind woofers with greater installation depths when it comes to bass performance.

✓ Clever bis ins Detail

The extremely torsion-resistant sandwich paper cone in conjunction with the heavy-duty double voice coil 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.

A special highlight: the magnet system has a threaded hole on the back and thus enables the woofer to be screwed to the rear wall of the housing. In this way, housing vibrations can be effectively reduced even with thin walls, because with flat constructions every millimeter of depth sometimes counts.

✓ Flexible connection

The design as a double voice coil woofer brings with it a lot of flexibility in terms of the choice of amplifier. Whether 1 x 4 ohms, 2 x 2 ohms or 1 x 1 ohm impedance - every configuration is possible with this deep bass specialist.

✓ "All inclusive" for the do-it-yourselfer

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 optimal bass performance with DIY installations, our technical data sheet contains recommendations for closed and bass reflex cabinets with all parameters such as net volume, tunnel tuning frequency or DSP settings.
