Thin is in

Helix builds their Esprit subwoofers to fit in places that normal subs won't. Coming in at just 2-1/2" deep, the Esprit E8W 8" shallow-mount sub lets you get creative with placement while giving you impressive bass. German engineering shines through on this sub, as Helix uses technology from their high-end Precision Series to create a super-slim driver that delivers superior performance and handles plenty of power. You'll enjoy highly accurate bass reproduction in applications where space is an issue.

Built for fidelity and performance

You can drive this sub hard, and the rigid fiberglass-coated, honeycomb membrane cone will still maintain its shape, so your bass stays true. Power handling is also enhanced by a large rubber surround that helps keep the cone under control, as well as a sturdy die-cast aluminum basket that provides a non-resonant, stable platform. You can wire this dual-voice-coil sub for 4-ohm or 1-ohm impedance, which gives you a little more flexibility as your system changes.

To drive this single subwoofer, we recommend a mono amplifier rated between 150 and 300 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Enclosure Compatibility


Cone Design: The woofer uses a Honeycomb cone membrane coated with fiberglass. The rubber surround is resistant to UV rays for added durability.

Dual 2-ohm Voice Coils: This woofer features dual 2-ohm voice coils, offering wiring flexibility. When the voice coils are wired in parallel the woofer presents a 1-ohm load. When the voice coils are wired in series the woofer presents a 4-ohm load.

Cast Aluminum Basket: The die-cast aluminum basket resists flexing and resonance (ringing).

Terminals: The woofer features two pair of gold plated spring post terminals. They accept pin connectors or bare wire up to 12-gauge.

Enclosure Compatibility

Sealed Box: For the best sound quality when you're short on space, use a sealed enclosure; the optimum internal volume is 0.5 cubic foot. Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable to all types of music.

Ported Box: The recommended ported box has an internal volume of 0.7 cubic feet with a 3" diameter x 9-3/4" long port tube, giving a tuning frequency of 50 Hz. Ported (or vented) enclosures typically provide better overall efficiency than sealed so they are suitable for use with smaller amplifiers, giving you more bass output from less power.
