5-1/4" (130mm) 2-Way Component System




Symmetrical field Geometry™

Symmetrical field Geometry™

SFG technology determines the precise shape of the magnetic field in and around the magnetic gap. This provides identical motor force both above and below the gap. The benefit is low distortion, even at high excursion.

Pure-titanium-dome Tweeters

Pure-titanium-dome Tweeters

The JBL pure-titanium dome is suspended in a high-loss rubber surround that is designed to damp dome resonances. The benefit is smooth response, free from fatigue, even at high-output levels.

Edge-wound aluminum Voice coils

Edge-wound aluminum Voice coils

Using this 2" ribbon-shaped wire allows JBL engineers to precisely specify the number of windings in the magnetic gap. The benefits are distortion-free extension of high frequencies and increased power handling.

Fourth-order linkwitzreily Acoustic passive Crossovers

Fourth-order linkwitzreily Acoustic passive Crossovers

Steep slopes minimize interaction between drivers. The benefit is uniform system response in a variety of vehicle mounting locations.
