Upgrade with Focal quality

You're ready: to do away with unbearable factory sound and to gain a totally authentic experience listening to music in the car. With Focal's Universal Integration Series speakers installed in your car, a new era has begun — one in which it's easy to enjoy every moment of your drive. Focal provides such a dramatic boost in sound quality by applying much of the same technology in these car speakers that they use in their studio and audiophile-grade home systems.

Upgrade with Focal quality

You're ready: to do away with unbearable factory sound and to gain a totally authentic experience listening to music in the car. With Focal's Universal Integration Series speakers installed in your car, a new era has begun — one in which it's easy to enjoy every moment of your drive. Focal provides such a dramatic boost in sound quality by applying much of the same technology in these car speakers that they use in their studio and audiophile-grade home systems.

Superior materials and design

Focal's ISU 200 component speaker system employs a polyglass 8" woofer cone to give you a warm, natural sound with enhanced strength for accurate playback with no added resonances. An aluminum/magnesium inverted dome tweeter, backed by an in-line crossover, delivers astonishing detail in the high range and integrates an acoustic horn design for an improved soundstage across your dash. Focal also gives you two mounting options for a smoother installation. 

High-sensitivity design

Planning to drive these speakers off a head unit? No problem. They're designed to take advantage of every bit of power supplied to give you the best audio quality possible. However, Focal's famous sound soars when powered by an aftermarket amp!

Grilles are not included; the factory grilles should be suitable for most applications.

Product Research

Woofer
Tweeter

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 butyl rubber surround is resistant to ultraviolet rays, temperature extremes, and humidity to add to the speaker's reliability and longevity.

Woofer 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.

Tweeter

Inverted Dome Tweeter: The tweeter is an inverted aluminum and magnesium 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.

Note: When flush mounted, the tweeters are pressure fit into the opening, with nothing holding them from behind, so the cutout diameter is very important.

Mounting Options: The tweeters include flush mount and angled surface mount housings:

  Flush Mount Angled Surface Mount
Mounting Height 0.312" 2.105"
Mounting Depth 0.658" 0.875" (screw depth)
Frame Diameter 1.957" N/A
Cutout Diameter 1.74" N/A
Width N/A 1.968"
Surface Depth N/A 3.114"

Tweeter Crossovers: The included 18" 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).

Q
is that a direct replacement for the MX5 2006? or i have to replace the Amp because of the different OHM?
ariel isaac franco  Sep 05, 2021
1 answer
A
If you have the factory Bose system you will have to bypass the amp. Not sure about the non-Bose system. Thankfully, a crutchfield rep can walk you through it. Google "miata bosectomy." There's a great forum post about it.
garson  Sep 05, 2021
Q
Has anyone tried using these to replace OEM JBL 8" woofers in those Sequoias and Tundras? These seem like they would be a fantastic option without having to do crazy mods to the system.
bloodcx  Jul 12, 2021

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.

Q
where do the inline crossovers cut the frequencies. High pass? Low pass? What frequencies please.
daniel  Jul 07, 2020

A
High pass to the tweeters. I put these into a 05' Mazdaspeed miata and they sound great; highs and lows are both excellent powered with a Kenwood Excelon head unit. Not sure the specific frequency of the crossover, but I'm sure they are designed to provide the tweeters with exactly what they can handle.
peter  Jul 07, 2020
A
I don't think Focal provides this data, but based on other Focal tweeter specs available at Crutchfield it's around 4 kHz.
oleg  Jul 07, 2020
Q
why all the q&a in here has to do with mazdas, I was looking for a fit placement for my 2013 mustang with a shaker 500 system?
keith  May 08, 2020

You can check to see if this will fit your vehicle by using our Outfit My Car tool: http://www.crutchfield.com/car/carselector.aspx For additional details on fit or installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on if this will fit and what you will need for an installation in your vehicle.
kristina  May 21, 2020 (Staff)
Q
1. How many voice coils 2. Is that 4 ohms for the woofer and 4 ohms for the tweeter allowing them to be run on a 8 ohm amp? Or 4 ohm total woofer and tweeter that would need a 4 ohm amp?
edwin  May 06, 2020
1 answer
A
4 ohms speakers should not be installed on amp that can handle 8+ ohms. You can't do 4+4=8 ohms because they are not the same speakers - woofer adds load on low frequency and tweeter on high.
oleg  May 06, 2020
Q
Do these come with grilles?
brandon  May 30, 2019
4 answers
A
No they don't
franklin  May 30, 2019
A
They do not. I assume that the idea is to drop them into stock locations in your car, negating the need for a grills. Still, I thought it would be nice to have them too :).
david  May 30, 2019
A
No, but crutchfield sells 8" grills the work fine
john  May 30, 2019
A
Yes, they do, though I mounted mine in an existing spot and used the existing grille in the car door to keep a factory look.
andrew  May 30, 2019
Q
What size (diameter) are the included tweeters?
daniel  Nov 03, 2018
1 answer
A
They do not list an exact dimension for the inverted dome tweeters. You'll find the mounting dimensions for the tweeters (for both flush & surface mount) by clicking the "Details" tab on the component's main webpage and scrolling down below the "Features & Specs" table.

Q
Are these the Matched pair bose speakers used in Miata 2006 to 2008?
