Focal applies the same technology they use in their studio and audiophile-grade home systems to their Integration line of car speakers. The Integration IS 165 component system features 6-3/4" woofer cones made from 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.
The separate 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.
Built-in crossover networks
The crossover networks are built-in, so you don't have those extra boxes to install. Integration speakers allow you to put Focal sound quality and construction into your vehicle, so you can enjoy a dramatic jump in performance over your old speakers.
Note: Focal describes this model as a 6-1/2" speaker. Most manufacturers designate this same frame size as a 6-3/4" speaker. For simplicity's sake we list it as a 6-3/4" speaker.
