With a 45Hz - 21kHz frequency response, these JBL GX963 3-way car speakers utilize 6" x 9" polypropylene woofer cones to deliver a complete range of lush, high-fidelity tones throughout your vehicle as you drive.
Installed these JBL speakers in my RV and they sound much better than the speakers I replaced. The highs are clean and crisp and there is ample bass. The construction seems very well thought out and they appear well made. I am very pleased with these speakers!
