FEATURES


Features:

  • Plus One Woofer Cones: The Plus One speaker cones offer more surface area than many other speakers that fit in the same size opening. This is accomplished by using a new basket design and hi-roll surround. The result is greater bass output and an increase in efficiency.
  • Voice Coil: The Primus Series speakers feature 3-ohm voice coils to compensate for the high in-line resistance of small gauge factory wiring. They extract every watt from the factory receiver, increasing overall system output and efficiency (relative to 4-ohm speakers). The speakers also benefit from increased power when you upgrade the wire and add aftermarket amplifiers capable of powering a lower impedance load.

  • Excellent upgrade for my Corvette. Sound quality is top notch. Just the right balance of all the frequencies. Haven’t tried to crank up the volume yet, but I think I don’t need to. Volume is already enough at 12 o’clock.

  • My Lexus sounds so much better after I got these speakers installed. really got that full sound with clear highs and the mids are pretty warm. good sounding bass even with the size. installation was as fast as I imagined.
