About the JL Audio ZR100-CT

Crisp, clean sound

JL Audio's ZR100-CT high-performance 1" aluminum dome tweeters bring out the subtle details in your music so you get a clear sonic picture of all the instruments in the stereo mix. You'll enjoy the extended high-frequency response offered by an aluminum dome, while special-design butyl rubber surrounds eliminate the shrillness that can plague lesser metal tweeters.

Crisp, clean sound

JL Audio's ZR100-CT high-performance 1" aluminum dome tweeters bring out the subtle details in your music so you get a clear sonic picture of all the instruments in the stereo mix. You'll enjoy the extended high-frequency response offered by an aluminum dome, while special-design butyl rubber surrounds eliminate the shrillness that can plague lesser metal tweeters.

The crisp-sounding ZR100-CT tweeters feature strong neodymium magnets, ferrofluid-cooled for reliable performance. JL Audio's ratcheting swivel rotation (RSR) system allows you to aim these tweeters for the best possible stereo image in your vehicle.

Note: These tweeters must be used with the supplied in-line high-pass filters, or an appropriate external crossover. Failure to do so could lead to damage to the tweeters not covered under the warranty.

Installation note: You'll need a pair of our universal backstraps to install these tweeters in the factory locations.

Features

Aluminum Dome: The ZR component system tweeters utilize a 1" ultra-light aluminum dome, delicately suspended with a synthetic rubber, positive-roll surround to damp fatiguing ringing and preserve high-frequency definition. A Nomex voice coil former is used to further reduce mass.

Neodymium Magnets: The high-energy neodymium wafer magnet and machined field structures provide a dynamically stable field for the low-mass voice coil.

Performance: Each pair of ZR tweeters is tested and matched to within 1 dB of JL Audio's reference curve to ensure optimum system performance.

High Pass Crossover: The JL Audio external high pass crossover networks (12 dB/octave) offer high-end filter components such as precisely wound air-core inductors and high-quality, low-tolerance capacitors. Tweeter protection is also incorporated into the crossover networks. The crossovers measure 0.895" in diameter and 3.285" in length.

Mounting Options: A very shallow flush-mount system makes it easy to integrate the ZR tweeter into many vehicle interiors. Two additional mounting fixtures are also included for each tweeter. The tweeters come mounted in enhanced flush mount fixtures with silver trim and a JL Audio badge. The system also comes with compact flush-mount fixtures and angled, surface-mount fixtures. The mounting dimensions for each mounting option are as follows:

Mounting Fixture Mounting Depth Mounting Height Frame Diameter Cutout Diameter
Enhanced Flush Mount 0.566"
(1.5" screw depth)
0.48" 2.126" 1.725"
Compact Flush Mount 0.454"

Well seems like JL Audio are one of the leading brands of speakers and I have a pair of JL Audio tweeters and by far have out performed the rest. [ Roel  May 10, 2017 ]

I have jl coaxials with aluminum tweeters that sound awesome and think adding these will add some extra treble and bring my soundstage up higher from the doors by mounting them on the dash pillars [ Christopher  Mar 30, 2016 ]
