Helix K 10SE.2 (Downfire Subwoofer)

HELIX K 10SE.2 – Shallow Enclosure Subwoofer with Rich Bass Performance

The HELIX K 10SE.2 is designed for hidden and space-saving bass installations without compromising performance. With its extraordinarily shallow housing and compact dimensions, it easily competes with much larger subwoofers in terms of sound pressure and bass depth. Perfectly suited for discreet installations like under a vehicle’s double loading floor, this subwoofer combines smart design with outstanding acoustics.

To ensure stability and vibration-free performance, the magnet system is screwed directly to the enclosure’s back panel for additional reinforcement. The torsion-free sandwich paper cone and heavy-duty dual voice coil effortlessly transform amplifier power into tight, controlled bass while maintaining sonic precision.

The dual voice coil design allows flexible wiring options (2 x 2 Ohms, 1 x 4 Ohms, or 1 x 1 Ohm), making the K 10SE.2 adaptable to a wide range of amplifiers. Thanks to its downfire enclosure technology, the woofer is well-protected while ensuring ideal bass dispersion. The integrated Velcro feet also secure the subwoofer in place on carpeted surfaces, often eliminating the need for additional fastening.
