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.
Helix was thinking a little outside the box when they designed the Precision P8W 8" 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 250 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. For best results, mount this subwoofer in a ported enclosure.
To drive this single subwoofer, we recommend a mono amplifier rated between 200 and 375 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.
