About the Focal ISS 170
Audiophile-grade engineering
You can use this angled tweeter mount to improve high-frequency dispersion in problem vehicles.
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. The Integration ISS 170 component system includes 6-3/4" woofers with cones made from Polyglass, a material that combines the warm sound of cellulose with the strength of glass, so they'll play accurately with no added resonances.
Adjustable tweeter
Each 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. Focal includes a low-profile surface mount and an angled mount so you can set up the tweeter for the best possible imaging in your vehicle.
Built-in crossover networks
The crossover networks are built-in, so you don't have those extra boxes to install. Low-profile 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. Grilles are not included; factory grilles are appropriate for most installations.
Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

Product Research
Woofer
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 rubber surround is resistant to ultraviolet rays, temperature extremes, and humidity to add to the speaker's reliability and longevity.
Phase Plug: The bullet-shaped phase plug in the center of the woofer ensures a smooth, flat off-axis frequency response by preventing the high frequency sound waves emanating from one side of the cone from interfering with sound waves from the other side of the cone.
Crossovers: The woofers' crossovers are mounted to the wire terminals.
Tweeter
Inverted Dome Tweeter: The tweeter is an inverted aluminum dome, producing a broad sound stage. The tweeter has a Neodymium magnet to provide a powerful magnetic field for the voice coil, while still maintaining the tweeter's compact dimensions.
Mounting Options: The tweeters can be flush mounted or surface mounted; two types of surface mount housings are included, one low profile and one angled:
| Flush Mount | Low Profile Surface Mount | Angled Surface Mount | |
|---|---|---|---|
| Mounting Height | 0.3" | 0.894" | 1.933" |
| Mounting Depth | 0.55" | 0.875" (screw depth) | 0.875" (screw depth) |
| Frame Diameter | 1.871" | 1.88" | N/A |
| Cutout Diameter | 1.67" | N/A | N/A |
| Width | N/A | N/A | 1.895" |
| Surface Depth | N/A | N/A | 2.839" |
Crossovers: The included 38" tweeter wires have integrated crossovers. The tweeter ends of the wires have quick-slide terminals that easily connect to the wires soldered to the tweeters. The input end of each wire has three leads, a negative and two positives. The positive leads are labeled Car and Display, with a lower output level from the Car lead (useful because the placement of the woofer in a typical car installation requires the tweeter output be lowered to maintain a balanced sound).
Installation
Woofers: Brackets and wiring harnesses are included to make the woofers an easy fit in select Scion, Toyota and Nissan vehicles. The tweeter mounting hardware is not vehicle specific. Please refer to the Crutchfield Vehicle Selector to confirm fit in your vehicle.

Focal Sound is superb and really made a huge difference is a factory System. I could not have acomplished this without the support from Crutchfield as these component Speakers require proper installation of which Crutchfield guided me the whole way via multiple phone calls.
