Featuring a coaxial connection for superb audio quality, this speaker provides warm low end frequencies and crystal-clear trebles to ensure music or spoken audio sounds its best. In cars where the speakers are located low in the doors, mids like these may be just what the doctor wants. I find the resonance to be right around 70 Hz, so it's pretty safe to use these speakers right down to 80 Hz or so. JBL uses a three-ohm coil to compensate for the increased resistance in the very small gauge wire used by OEM car manufacturers, but I'll bet the people who use larger gauge wire aren't complaining!

Thursday Diva's “Follow Me” is very rich and warm-sounding with good definition in the lower registers and simply excellent clarity and tone in the upper mid-range. You'll find JBL's unique Plus One woofer cone design at work here, which expands the diaphragm area of the cone to give you better low-frequency response. The GTO629s are conventional two-way mid-tweet type coaxial speakers using a six-inch (152 mm) mid-range and one-inch (25 mm) textile dome tweeter. The speakers' patented UniPivot tweeter positioning allows users to adjust the tweeter angle, directing the sound toward the listening area for optimal sound staging.

You will be fine for the front speakers and as for the rear going from a 4 ohm speaker a 2 ohm speaker will actually increase the output from the radio making good it a little louder. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. So what they're implying is that this is designed to work in the 4 Ohm speaker class and that they expect that your speaker wiring will add an extra Ohm to the equation. They are designed with a carbon-injected cone material to accurately reproduce music the way the artist originally intended.

It's not as loud as I thought they would be so I tried them out on my Tahoe with an aftermarket amp and they sounded great. If you use one, though, you’ll get a better sound, less distortion, and possibly more enjoyment (and volume) out of it. The silk dome tweeters provide a smooth and detailed high-frequency response, producing clear vocals and crisp instrumentals. These are excellent speakers 🔊 that have definitely helped the stereo system in one of my GMC Trucks sound better.

The sonic performance of various individual loudspeakers can be very different and a very personal preference. JBL is most known for its low-cost Bluetooth speakers, but the American company also offers some excellent headphones.

All in all, the system's response curve is relatively flat and, dare I say, flatter than a few systems I've measured that cost considerably more money. To improve aim and focus of the angle-mounted tweeter output, JBL's UniPivot system allows it to rotate almost 360 degrees. This is something I have noticed in the past with JBL loudspeakers; and, in fairness, I know that every JBL speaker system undergoes extensive listening by very experienced engineers and I have no doubt the “polite” top end of the GTO629 is exactly as the engineers have intended. And better performance makes the speakers an ideal replacement for factory speakers as well as for any aftermarket speaker installation. inch two-way car audio speaker system with exceptional sound quality and a powerful listening experience.Three-ohm voice coils in GTO 629 speakers allow compensation for any added resistance by thin factory-installed speaker wiring. It includes a pair of studio-quality headphones, and a guide to getting the most out of your session, and a few other necessary items. The ability to use a smaller area is an advantage of this design, which explains its appeal in automobile audio. The GTO629 features a cone woofer constructed from carbon-injected Plus One material, which increases cone area and enhances bass output without sacrificing sound clarity. Featuring a tweeter and a passive crossover, the JBL GTO629 ensures that sound is properly balanced and delivered to the listener.

Easy to install and built to last, this innovative line of speakers is engineered for the difficult environments and conditions both in and outside today’s automobiles. As a result, the low-frequency response is improved, and it takes less effort to generate those crucial musical notes that larger speaker sizes are frequently associated with.These JBLs offer slightly lower impedance than standard car speakers, so they'll safely draw a little more power from your car stereo, yielding big volume even with low-powered factory radios.
