Helix IK E10.1-SVC2 MK2 – compact 10″ downfire subwoofer with 1 x 2 Ω voice coil
The IK E10.1-SVC2 MK2 is the single-voice-coil version of the HELIX IMPACT IK E10.1 MK2 downfire enclosure. HELIX positions it as a performance subwoofer for everyday use: strong bass from a compact ported box with a 250 mm (10″) chassis.
The downfire design uses the vehicle floor to reinforce low frequencies and protect the driver, and the 1 x 2 Ω voice coil is intended to extract maximum power from compatible amplifiers. The MK2 plug-in terminal adds a MOLEX connector alongside the screw connection.
Key Features
- Downfire design: Firing towards the floor spreads bass through the vehicle and protects the driver.
- Compact ported enclosure: Bass-reflex tuning at 43 Hz for high sound pressure in a space-saving format.
- 250 mm IK W10-SVC2 driver: Hand-scooped paper cone combined with a heavy-duty driver system.
- 1 x 2 Ω single voice coil: Designed for maximum power output with suitable amplifiers.
- Recommended amplifiers: The page names the HELIX AMPLIFY 201 X-OVER, HELIX AMPLIFY 201 DIRECT and MATCH UP 1FX as compatible.
- 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: Velcro-backed feet hold the enclosure in place.
- Durable finish: Carpet covering with an embroidered HELIX logo.
