Speaker Specifications

Crossover Frequencies: Onboard

High-Frequency Transducer: 25mm (1") balanced-dome My-Ti™ dome

Controls/Adjustments: None

Low-Frequency Transducer: PlusOne® HCL™ honeycomb-laminate cone

3-1/2 inch Two-Way loudspeaker with Plus One® woofer cone and 3/4 inch My-Ti ™ tweeter. This is the perfect speaker for upgrading stock dash loacations.

Patented Plus One® woofer cones

The JBL-only Plus One® woofer cone (patent no. 7,548,631 B2) is exceptionally stiff, lightweight and has up to 25 percent more active surface area than you’ll ever find on competing models of the same size. You get an audible increase in bass output and efficiency.

Increased power handling with My-Ti™ tweeters

My-Ti™ tweeters deliver increased power handling, reduced distortion and increased efficiency. A Mylar®/titanium composite dome makes way for open, smooth spacious sound and a seamless transition between the middle and high frequencies.

Optimal imaging with Unipoint™ rotating tweeter

Another JBL® feat of engineering: You can rotate the tweeter pod nearly 350 degrees to aim it at the listening position for better high-frequency response and optimal imaging.

JBL I-Mount™ for easy installation

I-Mount™ (patent no. 5,859,917) allows for more precise imaging and simplifies tweeter installation, with angle-, surface- or flush-mount options. It’s a tweeter mounting system that makes for one of the easiest and most versatile installations you’ve ever done.

Outstanding audio output

This speaker offers 25 watts RMS, 75 watts of peak power handling, 89dB sensitivity, 2-ohm impedance and an accurate frequency response of 90Hz to 20kHz. Hit the gas and have fun.
