Helix IK E10.1-DVC2 MK2 – compact 10″ downfire ported subwoofer, ISM-ready
The IK E10.1-DVC2 MK2 belongs to the HELIX IMPACT family of enclosure subwoofers. It is designed for customers who want deep, powerful bass from a small footprint instead of a bulky conventional box, combining a bass-reflex enclosure with a 250 mm (10″) driver.
Its downfire layout uses the vehicle floor as a reflecting surface to reinforce low-frequency output, while also protecting the driver and allowing a lower installation profile. The MK2 generation adds a new plug-in terminal with MOLEX connector and makes the enclosure ISM-ready, so it can later be converted to an active subwoofer by exchanging the terminal.
Key Features
- Downfire design: The driver fires towards the floor, which spreads bass through the cabin, boosts low-frequency output and keeps the cone protected.
- Compact ported enclosure: Bass-reflex tuning (43 Hz) delivers high sound pressure while keeping the installation space-saving.
- 250 mm IK W10-DVC2 driver: A very stiff cone of hand-scooped paper fibres and a heavy-duty motor system convert amplifier power into bass without compression.
- Flexible voice-coil wiring: The dual voice coil can be configured at the terminal as 1 x 1 Ω (for HELIX and MATCH monoblocks), 1 x 4 Ω (for bridged channels of multichannel amplifiers such as HELIX AMPLIFY) or 2 x 2 Ω (for parallel operation on multichannel units such as HELIX NEXT and MATCH UPGRADE).
- ISM-ready: Swapping the passive terminal for the optional IMPACT Subwoofer Module ISM 400.2DSP turns the IK E10.1-DVC2 MK2 into an active subwoofer – a direct-fit amplifier module with integrated DSP intended for upgrading modern vehicles with factory sound systems, without rebuilding the existing installation.
- Plug-in MK2 terminal: The new detachable terminal provides a screw connection for ordinary speaker cable plus a standardised MOLEX connector for custom wiring harnesses – HELIX flexibility combined with the plug & play approach of the MATCH ecosystem.
- Short-circuit protection: Because the plug is removed together with the cable, no bare wire ends are left loose in the vehicle, and the enclosure can be taken out and refitted in seconds.
- Secure placement: Feet fitted with Velcro keep the enclosure firmly in position.
- Durable finish: Hard-wearing carpet covering with an embroidered HELIX logo.
