Helix U 10A (Active Subwoofer)

The HELIX U 10A active subwoofer is the perfect solution for car audio enthusiasts who want powerful low-frequency performance without sacrificing space. Engineered with a built-in Class AB amplifier (180 W RMS) and a sturdy die-cast aluminum housing, this subwoofer ensures precise, distortion-free bass reproduction while maintaining excellent heat dissipation.

Thanks to its 10” / 250 mm heavy-duty chassis with an aluminum cone and heat-resistant voice coils, it efficiently transforms amplifier power into impactful sound pressure. With advanced controls such as an adjustable steep lowpass filter, sensitive phase adjustment, and subsonic filter, it allows seamless tuning to match any vehicle’s acoustic environment.

Integration is simple with 2-channel highlevel inputs (with Auto Turn-On), lowlevel RCA inputs, and a remote control for volume adjustment included. Its extra-slim cabinet design makes it ideal for under-seat mounting or other tight installations, offering bass enhancement without compromise.
