Our take on the Focal Integration ISC 690

by John Pollard
Focal

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Audiophile-grade engineering

Focal applies the same technology they use in their home audiophile-grade systems to their Integration line of car speakers. Their Integration ISC 690 6"x9" speakers feature cones made from Polyglass, a material that combines the warm sound of cellulose with the strength of glass, so they play accurately with no added resonances.

Focal ISC 690 6X9" Coaxial 2 way Speakers

You can aim the tweeter to improve high-frequency dispersion in many vehicles.

Adjustable tweeter

The Integration processed-aluminum inverted dome tweeter features a built-in phase plug and wave guide, which act together to improve the dispersion of the high frequencies for a more effective 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 included.

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 listeners.

Crutchfield Customer Review (What's this?)
 
Great speakers with some awesome bass. I currently have then paired with an Alpine HD149BT and everyone thinks I have a small sub. Truth is, there's no amp, no sub. I love these speakers. Easy installation due to the shallow depth too.
Cons:
Crystal clear with great bass and midrange.

Crutchfield Customer Review (What's this?)
 
In 2011, I installed a pair of Clarion SRQ6932R speakers I bought from another retailer into the back of my 2004 Sebring convertible and thought that they sounded pretty good. This year, I checked out several sites to find a better speaker. I'm driving these with a 60Wx4 JVC amplifier I installed in 2012 along with a JVC head unit I purchased from Crutchfield. However, after installing the Focal ISC 690's I was wrong. These speakers have not only amazing bass reproduction but also a very well balanced and clear high and mid-range. I believe that the high range is due to the ability to modify the focus of the tweeters. These speakers actually took up less room than the Clarion's. I have to say that this amazed me considering the amount and quality of sound produced by the speakers. Sadly, I am going to have to replace my Pioneer TS-G971M front speakers as the Focal's out produce them badly and the sound image is biased to the back. So, the good is I love the Focal's and the bad is I have to buy more Focal's? I'm thinking I'm better off with another set for the front!
Pros:
Awesome sound reproduction. Easy installation. Great for my amp.
Cons:
I'd say price but you get what you pay for?
