IK W Series – Redefining Subsonic Boundaries
Building on core ideologies and technologies developed from the mighty Q series subwoofers, the latest IK W units offer a powerful combination of lighter weight and far higher output capability. If you're looking for the perfect subsonic solution, one that combines all the attributes important to accurate subbass with the backing of a proven equipment designer; Helix's IK W subwoofers are the perfect option. They'll return enormous kinetic force with astounding accuracy across all applications.

Design Ideologies
Providing powerful bass in a compact format, these are the performance subwoofer for everyday use. The IK E8.1 enclosures delivers deep, punchy bass in a space-saving design; ideal for those who want rich low-frequency performance without the bulk of a conventional subwoofer enclosure.

Smart Downward Firing Design
The intelligent downward firing construction ensures optimal bass dispersion in the vehicle. It uses the vehicle floor as an acoustic reflection surface to intensify low-frequency output, offers optimum protection for the speaker and allowing for a lower-profile design. Combined with bass-reflex technology and a powerful 250 mm chassis, it provides a dynamic bass experience with impressive sound pressure while making efficient use of available space.

High-Grade Components For Sonic Strength
The IK E8.1 features the 8″ / 200 mm IK W8 driver. Its extremely stiff cone made of hand-scooped paper fibers combined with the heavy-duty driver system converts amplifier power easily and without compression effects into loads of sound pressure; while also scoring sonically with its accurate yet subtle beats.

Flexible Connection
With the option of either single or dual voice coil configuration, there is a perfect IK E8.1 enclosure for every amplifier setup, allowing you to maximise your power output.

Rugged, Practical And Easy To Install
The enclosure is covered with a sturdy carpet featuring an embroidered logo, making it not only visually appealing but also robust enough for everyday use. The feet, equipped with Velcro tape; provide a secure and stable stand within the vehicle. Furthermore the pluggable terminal greatly simplifies installation and facilitates the removal of the subwoofer when extra space is needed. The detachable connector prevents short circuits by ensuring that no exposed wiring remains in the vehicle.
