Our take on the Focal Access 100CA1 SG

by John Pollard

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. You can pivot the tweeters toward your listening position to optimize stereo imaging.

High-quality parts

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.

Features

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.
