About the Focal Integration ISC 165
Audiophile-grade engineering
You can aim the tweeter for better high-frequency dispersion.
Audiophile-grade engineering
Focal applies the same technology they use in their studio and audiophile-grade home systems to their Integration line of car speakers. Their Integration ISC 165 6-1/2" speakers use cones made of Polyglass, a material that combines the warm sound of cellulose with the strength of glass, for a woofer that plays accurately with no added resonances.
Adjustable tweeter
The Integration processed aluminum inverted dome tweeter features a built-in phase plug and wave guide, which act together to increase the power of high-frequency notes and improve the stereo soundstage. You can also tilt the tweeter for better imaging in many vehicles.
Integration speakers allow you to put Focal sound quality and construction into your vehicle without a lot of muss and fuss, so you can enjoy a dramatic jump in performance over your old speakers.
Grilles are not included; the factory grilles should be suitable for most applications.

Features
Polyglass Cone: The woofer cone has a cellulose pulp base and is coated with a uniform deposit of hollow glass microballs. The addition of the Polyglass layer significantly increases the cone's rigidity without adding much weight. This combination takes advantage of the accuracy and neutrality of the hard outer surface, but maintains the superior damping characteristics of the cellulose pulp.
Surround: The butyl rubber surround is resistant to ultraviolet rays, temperature extremes, and humidity to add to the speaker's reliability and longevity.
Voice Coil: The voice coil is wound around a 1" diameter low-mass Kapton former, ensuring no coil deformation.
Inverted Dome Tweeter: The tweeter is an inverted aluminum dome, producing a broad sound stage. The tweeter is angled and rotates on its post, so it can be pointed toward the listener.
Size Classification Note: Crutchfield has traditionally referred to this size speaker as a 6¾", while some manufacturers, including Focal, call it a 6½". Please enter your vehicle information to confirm fit.
