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.

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.
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.
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.
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.
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.
This JBL® Grand Touring™ Series speaker is designed to fit right into factory locations with little or no modification.
