Overview

Our take on the JBL GT6-6

If you want speakers that'll make the most out of the power they're given, JBL's GT6 Series speakers are a smart way to go. They're sensitive enough to perk up the sound of a factory radio, but tough enough to handle an outboard amplifier too. These JBLs will impress you with their powerful bass, clear highs, and strong output.

Oversized cones, powerful tweeters
The GT6-6 2-way speakers employ 6-1/2" Plus One polypropylene woofer cones — with 30% more surface area than most other 6-3/4" speakers — to dish out the lows with accuracy and strength. The vented motor design keeps the speaker cool and operating efficiently when you've got the volume cranked. Each 1" titanium-laminate tweeter projects highs that'll sparkle over the sound of road and wind noise.

Bought this from scratch and dent and was pleased other than it was previously installed but still functions like new and excellent for $25.00

Features

Plus One Woofer Cones: Each speaker uses a larger cone than other speakers of the same size. This is accomplished by using a unique basket design and hi-roll surround. The Plus One design offers greater bass output and an increase in efficiency.

Mounting: JBL refers to the GT6-6 as a 6-1/2" speaker. The 5.63" cutout diameter, however, fits the industry standard for a 6-3/4" speaker. Please confirm fit using the Crutchfield Vehicle Selector before purchasing.

Titanium Laminate Diaphragm Tweeters: Each speaker uses a titanium laminate diaphragm tweeter for fast transient highs with lower distortion.
