Built tough

Helix was thinking a little outside the box when they designed the Precision P12W 12" 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 350 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.

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 P 12W subwoofer can also be used in a sealed enclosure. The optimum internal volume is 0.75 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 1.75 cubic feet with a 4" diameter x 17" 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.
