Compact, space-saving, and designed for deep bass performance: The HELIX IK ER8.1 is the perfect subwoofer for seamless integration into flat spare wheel recesses. Its exceptional shallow round enclosure makes it an ideal choice for a space-optimised installation without compromising on a proper low frequency reproduction.

Outstanding bass in minimal space

The sophisticated, vented construction of the IK ER8.1 ensures outstanding sound quality and superior bass dispersion, delivering rich, powerful low frequencies across the vehicle. Equipped with an 8” (200 mm) woofer featuring a sandwich paper cone, this subwoofer brings impressive deep bass to even the tightest spaces.

Flexible installation and configuration

Thanks to the pluggable screw terminal, installing or removing the subwoofer is quick and secure. Additionally, with the choice between a 1 x 2 Ohms (SVC2) or 2 x 2 Ohms (DVC2) configuration, there is a perfect deep bass specialist for every amplifier setup to maximize power output.

Built for durability

The subwoofer chassis is flush-mounted, ensuring a sleek, space-saving design while providing enhanced protection. The enclosure features a sturdy carpet surface with the embroidered HELIX logo, adding both style and resilience to the unit. For added security, the included mounting kit ensures reliable fixation within the spare wheel recess.
