JL Audio TR400-CXi
Evolution™ TR Series 4" 2-way car speakers includes 4"x6" adapter plates
Item # 136TR400CX | MFR # 91029
Our take on the JL Audio TR400-CXi by Crutchfield's Buck Pomerantz
You need great speakers to turn the audio signals from your car stereo into music. The Evolution™ TR series speakers take advantage of JL Audio's extensive research and obsessive testing to deliver excellent performance at prices any audio enthusiast can afford. Evolution™ TR speakers come in a wide range of sizes so you can improve the sound in almost any vehicle.
JL Audio's TR400-CXi 4" speakers use mica-filled long-excursion polypropylene woofers for enhanced upper bass response that'll really fill out your drums and guitars. The 1/2" woven textile dome tweeters broadcast all the little details that bring your music to life. Ferrofluid cooled tweeters and butyl rubber surrounds mean that these speakers will bring you great music for many years to come.

Woofers: The JL Audio Evolution TR-series coaxial speakers feature injection-molded, mica-filled polypropylene cone woofers with 1" voice coils and flat symmetrical-roll spiders. The woofers use butyl rubber surrounds for reliability and strength.
Tweeters: The speakers have 1/2" treated textile dome tweeters with an integral phase plug and powerful, ferro-fluid cooled and damped neodymium magnets.
Crossovers: The TR-series coaxials use electrolytic capacitors on the 1st order high-pass filters. The woofer is unfiltered, using its engineered smooth roll-off characteristics to blend with its tweeter.
Flexible Mounting System: The speaker's 4 mounting tabs are scored to allow you to easily break them off for any application in which only 2 mounting screws are required. In addition, plastic 4x6 adapter plates are included to allow you to install these speakers into vehicles that use oval 4x6 speakers. Four 5/16" screws are supplied for attaching the speaker to the adapter plates.
Grilles: Two black metal mesh grilles and black ABS plastic grille frames are included with the speakers.
