High-end bass

Are you building a reference-level system in your vehicle? Helix created their Precision Series subwoofers for the mobile audiophile. Built from hand-picked components and assembled in Germany, these subs will create detailed low-end that perfectly complements a high-performance speaker system. From the tight, plucky punch of a bass guitar to the solid "thunk" of a kick drum, you'll be in sonic heaven with these subs.

Built tough

Helix was thinking a little outside the box when they designed the Precision P10W 10" subwoofer. They used Agave sisalana, an incredibly stiff natural fiber, coated in silk to create a lightweight, rigid cone that reproduces low frequencies with unerring accuracy. Combine this unorthodox cone with a seriously oversized voice coil, and you have a woofer that will handle up to 300 watts RMS without breaking a sweat. A big rubber surround takes a lot of abuse, while the die-cast aluminum basket won't add a hint of coloration to your bass. Don't be afraid to turn this sub up.

To drive this single subwoofer, we recommend a mono amplifier rated between 225 and 450 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

Features

Cone Design: The woofer uses a rigid sisal fiber cone with a durable rubber surround. The mechanical advantages of sisal, rigidity and inner damping, result in faster transients and precise detail.

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

Terminals: The woofer features a pair of spring post terminals. They accept pin connectors or bare wire up to 10-gauge.

Enclosure Compatibility

Sealed Box: Although designed for a ported enclosure, the P10W subwoofer can also be used in 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 1.25 cubic feet with a 4" diameter x 17.5" long port tube, giving a tuning frequency of 34 Hz and a -3dB point of 34 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.

This sub has just the right tone and power handling I was looking for. They're never boomy or too dark like lesser woofers tend to be, and it has great definition. I am very happy with this awesome driver.

Pros: Rich tone.
