Downfire subwoofer in a compact ported enclosure with 8” / 200 mm chassis, 2 x 2 Ohms impedance and IMPACT Subwoofer Module compatibility HELIX IK E8.1-DVC2 MK2

Compact and efficient design

The HELIX IK E8.1-DVC2 MK2 combines a compact footprint with powerful low-frequency punch and precise sound reproduction. Its downfire design ensures optimal bass distribution within the vehicle while simultaneously protecting the speaker chassis. Perfect for installations where both space and impressive output performance are equally important.

Impressive sound through smart engineering and premium components

The sophisticated ported enclosure design of the IK E8.1-DVC2 MK2 delivers impressive sound pressure levels and a remarkably deep low-frequency response for its size. At the heart of the system is the 8 inch / 200 mm IK W8-DVC2 driver, equipped with a high-power, high-excursion dual voice coil and a handcrafted paper cone. It ensures that amplifier power is translated into rich, powerful bass with minimal compression, delivering a dynamic and precise low-frequency performance.  

Smart terminal concept

The new connection terminal features a plug-in design and offers two connection options: a screw terminal for conventional speaker cables as well as a standardized MOLEX connector for custom wiring harnesses. This combines the best of two worlds: maximum flexibility for classic HELIX-style installations, plus a plug & play logic familiar from the MATCH ecosystem. It greatly simplifies installation and enables quick, safe removal and reinstallation when extra space is needed. The detachable plug also reliably protects against short circuits, as no bare cable ends remain inside the vehicle.

Flexible connectivity

Thanks to its dual voice coil design, the IK E8.1-DVC2 MK2 offers a high degree of flexibility when choosing the right amplifier setup. Depending on the application, the voice coils can be configured as 1 x 1 Ω (ideal for HELIX and MATCH monoblocks), 1 x 4 Ω (e.g. for bridged channels on powerful multi-channel amplifiers such as the HELIX AMPLIFY series) or 2 x 2 Ω (for parallel operation with multichannel-multitools, for example from the HELIX NEXT and MATCH UPGRADE lines) – making virtually any low-bass configuration easy to realize.

ISM-ready – optional active subwoofer upgrade

In the MK2 version, the IK E8.1-DVC2 is now ISM-ready: By replacing the passive terminal with the optional IMPACT Subwoofer Module (e.g. ISM 400.2DSP), the enclosure subwoofer can be upgraded to an active subwoofer in no time. As a direct-fit solution, the ISM 400.2DSP is a powerful amplified subwoofer module with integrated signal processor – developed for high-quality subwoofer upgrades in modern vehicles with factory-installed sound systems. This results in a compact all-in-one solution combining amplification and DSP signal processing for powerful yet controlled bass – without having to rebuild the existing system.

Built for durability 

The enclosure is covered with a sturdy carpet featuring the embroidered HELIX logo, ensuring both style and resilience. Furthermore, the Velcro-equipped feet ensure a secure and stable hold in the vehicle.
