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 570 5"x7" component speaker system employs a polyglass 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!

Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

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

Just Ok

Crutchfield customer from Shelbyville, TN on 8/12/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

Ok sounding speakers, for the price they should sound better. Disappointed in crutchfield. Mounting solution was not viable, just a old school steel bar with holes in that would not line up and hold speaker in. I wound up getting a new bracket 3d printed. In my opinion the manufacturer should spend more time developing install kits that actual fit the models they say the speakers fit it. Then if they don't Crutchfield should. Still trying to determine if the factory crossovers will sound better than the ones that come with the speakers. Will know that soon.

Pros: Liveable sound

Cons: Research into mounting hardware

Frank E from Barrington, NJ on 4/26/2019

2015 Ford Flex

Verified customer (What's this?)
Verified employee purchase (What's this?)

Installed for about a week now. Sound is superior over factory speakers. I installed these into a Ford Flex with no issues at all. The integrated crossovers make for an easy installation as well(No bulky/large boxes to hide). I am powering these with a 4 x 100 Skar amp. Once the DSP was set up correctly, they sound sweet.

Pros: Easy install without the bulky/large crossovers.

Cons: Not the cheapest speaker.

Just installed the focal lsu570 5×7 & tweeters in the front of my 2016 F350 with the Sony system. Mid base is better, but the tweeters are fantastic. I am amazed with the clarity. 100% better than the Sony. Fast shipping & outstanding customer service. ??

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.

Mounting Applications: Focal describes these woofers as 5x7, but they also fit many 6x8 applications. Please enter your vehicle information to confirm fit.

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).
