Our take on the Focal Integration ISS 690

by John Pollard

Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

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 690 component system includes 6"x9" 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.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.



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.

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.

Voice Coil: The voice coil is wound around a 1" diameter low-mass Kapton former, ensuring no coil deformation.

Crossovers: The included 7" woofer wires have integrated crossovers. The woofer ends of the wires have female quick-slides that easily connect to the woofer terminals.


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 include two types of surface mount housings, 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 19" 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).

Focal Integration ISS 690

Written By s.e.o., VA on Tuesday, July 29, 2014
Installed in front doors of a 2005 Toyota 4-Runner (non-JBL). Running off a Pioneer AVH-P3100DVD Head Unit (4 x 14w RMS). Still running stock rear door speakers. No amp. Had custom brackets fabricated for the 6x9 with foam rims to align with the stock foam on the door panel. Also went with inner & outer sound deadening on the front doors. These speakers are incredible, even with only 14w RMS pushing them they have incredible response down to about 50hz, really suprised how much punch they have in the 50-100hz ranges and that's just running on a head unit. Highly, highly reocmmend sound deadening and getting the tightest seal as humanly possible with the speaker enclosure in the doors, this is likely why they respond so well in lower frequencies only driven from the head unit. For lower volumes, more power is needed. I will be adding an amp soon. At low volumes, high end is weak without more power. I'll likely be adding an amp that can run at least 70w to each of these speakers. Crystal clear throughout all the spectrum and stable. Mid range is a bit "nasaly" and requires some EQ attention in the 200hz-1k range (could just be my head unit). Also tweets are very sensitive in the 16k+ range and require some EQ to eliminate pristine clarity on hi-hat riding. Again, could just be my head unit and resolve with more power to flatten out the source. Lots of data points, now just my personal opinion. These speakers ROCK. Compared them heads up to JL, Alpine ...
... Kenwood, Pioneer coax 6x9s and these were in another league. Hertz was similar, but had no component offering in 6x9. I refused to go with a 6.5" component because the 6x9 woofer just dominates the 6.5" in mid to mid-low output. The Pros: Crystal Clear, Highly Sensitive, Runs Great with Head Unit Only (look into properly sealing w/ sound deadening), Excellent Bass, Tight Response in Mid-Lows (I was hearing kick drum precision that I didn't even know existed).
Not really a con but likely requires amplification to open up the 10k Hz+ ranges at lower volumes. Again, not really a con and is solved with EQ and amplification - mid range seems to be the power house on the woofers.

Crutchfield Customer Review (What's this?)
Overall a great speaker. If you have a toyota with stock 6x9 speakers in the front, consider these. Whatever you do, DO NOT use the junk flat speaker adapters that Crutchfield and others try to provide. This will rob you of speaker depth, bass response, mid-bass and clarity.

It is VERY easy to re-use the stock speaker brackets of your toyota or purchase brackets that are ~1.5" in depth and are made for your car. You can either drop in 6x9 speakers (these fit with no mods to doors or anything else) or you can use a 6x9 to 6.5 adapter that will mount right on to your factory 6x9 brackets. Point is, when you're told these won't fit, or you need shallow mount speakers, don't believe it and don't do it.

Ok, that out of the way, these are indeed excellent speakers. I believe they would run fine even on an aftermarket head unit and no amp. But, a small amp would be even better. The highs are fantastic. Flat EQ, they sound great. The bass is good.

Mid-bass and mid-range is good, to a point. I found these couldn't quite handle the power and volume I was trying to play. They were 90% there, but not quite. With 200 watts and at louder volumes, the mid-range and mid-bass got a little muddy.

Also, don't believe the 6x9s don't sound good cause they are oval. Myth. If you get junk 6x9's then yes. But a quality 6x9 will sound great and compete with any 6.5" in its price range for clarity and will likely win for bass/mid-bass. 6.5 speakers only give you more options.
Crystal clear speakers, great bass, great tweeters. Would work well even with aftermarket head unit power and really will with 50 watts and up. I would put the bass of these speakers over any 6.5" in this price range, and the mid-range clarity is excellent as long as you're not trying to have a full blown heavy metal concert in your car. These are meant for factory fit replacement of your 6x9 front speaker cars and they are great for that.
Ran out of words available to me above. The only real con is for me at least is I wish they would handle a little more power. But this is only a con to me, I wanted really really loud speakers that could take up to 200 watts each. For most everyone out there these are fantastic and you won't find any faults.
