Product Research


Woofers: Each speaker features an interlaced Aramid fiber-reinforced IMPP (Injection Molded Polypropylene) cone woofer. With long Aramid fibers interlacing together inside, this IMPP cone design provides the strength and rigidity powerful bass sound requires. The high-density, compressed internal architecture is resilient, stacks up against high power and transfers sound very quickly. The result is full-bodied, rich sound.

Midranges: Each speaker uses a 1-5/8" Foamed Pearl PolyCarbon (PPC) balanced dome midrange with magnetic fluid and a strontium magnet. PPC is a lightweight material that delivers high sensitivity, open sound character and smooth extended frequency response. Its high inner loss reduces distortion. It's blended with special carbon fiber for UV resistance and protection against the harsh environment of a car.

Tweeters: Each speaker uses a 5/8" PET silver film dome tweeter and a 3/8" PET silver film super tweeter for crisp, clear highs.

Surrounds: For durability and a smoother response, each speaker uses a butyl rubber surround.

Mounting: The speakers can be mounted in a 6-3/4" opening, or, using the supplied adapters, the speakers can be mounted in an oversized GM/Chrysler 6-1/2" opening.
