Lifelike sound

Here's some good news for car audio fans. Focal's Access speakers have earned a reputation for delivering clear, natural sound that's unsurpassed in their price class. Now, Focal has actually lowered their prices on the latest editions of these remarkable speakers, so here's your chance to experience these coaxials for yourself. Focal inspects and tests every Access speaker to ensure that each one lives up to their high quality standards.

Excellent imaging

The Access 100CA1 SG 4" speakers feature stiff, woven glass-fiber woofer cones for precise sound reprouction. Focal's patented inverted-dome tweeters act like miniature woofer cones, dispersing high frequencies evenly with fine resolution and exciting dynamics.

The strong, lightweight ABS frame offers plenty of open space for unimpeded cone movement, along with plenty of venting to cool the voice coils. High-quality components in the built-in crossover ensure a seamless distribution of frequencies to the woofer and tweeter, for an extremely natural sound.

Great things in small packages

Written By Pontiac Jack, Pontiac, MI on Monday, February 10, 2014

I Used two sets of these in a regular cab Chevy truck ,one set in the b-pillars and the other in a set of PODS sealed boxes for four inch speakers. I have them amped with the alpine mrp-f300. The set in the PODS have better mids and even a little bass likely due to the sealed enclosure but that being said they all sound very exceptional for a four inch speaker. The highs are very "crispy" or "bright" and I'm good with that. I love being able to hear a drummer come off the high hat or the chimes over the thumps from the subs. If your looking for a good highs speaker, this will do the trick.

Pros: Great highs, decent mids, works well with and without amp

Cons: Don't expect a lot of bass. Its a four inch speaker.

Great little speaker

Crutchfield Customer Review (What's this?)

Definitely worth the extra money. The highs are very clear and their is even some bass on these two way speakers. When you crank it up they do not fizz out as well. I used with a Kenwood head unit.

Woofer: The light, rigid woven glass fiber woofer cone is humidity resistant. The butyl rubber surround is resistant to ultraviolet rays, temperature extremes, and humidity to add to the speaker's reliability and longevity.

Basket: The woofer features a basket made of 20% fiberglass filled ABS.

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 rotates on its post, so it can be pointed toward the listener.
