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 100 4" 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.

Focal Integration ISC 100 4" speakers

You can aim the tweeter for better high-frequency dispersion in problem vehicles.

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; factory grilles are appropriate for most installations.

Product Research

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.

Very Good

Written By natrpic, Springfield Mo. on Sunday, October 12, 2014

Crutchfield Customer Review (What's this?)

These are surprisingly full sounding for a little speaker.

Pros: Sound great! these are better then any 4X6 I listened to prior to buying these.

Cons: Adapter plate for a fit into a 4x6 hole is flimsy and it is not clear at all about mounting screws to hold speaker make for a very tight fit had to use a lot of pressure to get them in the hole as the screw hit edge of hole all the way around. will not knock down stars as the speakers themselves are really good.

Sound great

Pros: The work great running off the head unit might put more power to them and see how that works

Cons: None so far

Replacing factory speakers in a 1999 extended cab silverado

Written By Brian, Iowa on Wednesday, March 05, 2014

Crutchfield Customer Review (What's this?)

I replaced the speakers in the back extended cab area they were 4 by 5 the Focal Integration ISC 100 are 4inch and fit perfect with the adapter plate that was shipped free with purchase. I am running them off of an aftermarket kenwood hd reciver I purchased from Crutch field also I have no amp on them and they sound awsome real crips I also have a 10inch 100watt bazooka sub also to add to the bass if you are someone that likes bass i would recommend getting a sub Very satisfied would recommed. I might buy an amp also to put more power through them/

Pros: Good fit great sound better than factory

Cons: none

Get everything you’ll need to enjoy your new Focal Integration ISC 100

Reduce ambient road noise and your vehicle's "rattles," for better sound inside your car.
You may need speaker wire to connect your speakers to your amp or receiver.
Keep your speakers clean and dry. They compress to fit behind your speakers.
These speaker connectors are handy if you're running new speaker wire or if your speakers have oversized terminals.
The right tools will help keep your installation simple and clean.
