About the JBL By Harman GX963
Lively JBL sound
If your system feels flat or lacks energy, the JBL By Harman GX963 speakers bring your music back to life. The polypropylene woofer cone delivers a responsive low-end punch, while the balanced dome tweeter and super tweeter add clarity and sparkle to your highs. The result is a fuller, more exciting sound that makes every drive more enjoyable.
More cone area
JBL uses its patented Plus One™ woofer cone design to give you more surface area than typical speakers in this class. That extra cone area helps move more air, which means stronger bass response and higher sensitivity. In simple terms, you get louder, richer sound from the same power, making your upgrade feel instantly noticeable.
Smarter design
The JBL By Harman GX963 is ideal for drivers in Kenya looking for stronger bass and clearer vocals without heavily modifying the factory system. The edge-driven soft dome tweeter delivers smooth, natural highs while handling more power, so vocals and instruments sound more lifelike. A 3-ohm voice coil helps draw more power from your quality 4-channel amplifier, improving overall output even with factory wiring. JBL also includes a tweeter deflector waveguide to improve off-axis performance, so your music sounds clear no matter where you’re seated in the car.
