JBL GTO 629 6.5" Inch (165 mm) 2-Way Hifi Car Speaker Set by Harman Kardon - 180 Watt Pro Sound JBL Car Speakers (pair)

Product Information

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. The actual impedance of the system is three ohms, which allows greater power to be developed from the amplifier and results in increased output. With a sensitivity rating of 93 dB, it is capable of producing clear and loud sound without distortion. If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag. JBL engineers designed the GTO 629 coaxial speaker to produce strong, clear sound from a head-unit or amplifier capable of delivering up to 180 watts of power.

After a couple hours listening, I must admit I've found myself really enjoying the sound of the GTO629. The company is owned by Harman, which also owns AKG and Mark Levinson, so you might say it knows a thing or two about sound. The GTO 629’s Plus One carbon-injected cones provide more overall speaker-cone area than other cones in its class. 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. JBL GTO Series high-fidelity speakers are the ideal upgrade for any auto or audio enthusiast who’s looking to transform the driving experience. The JBL GTO629 speakers are a fantastic choice for car audio enthusiasts seeking high-quality sound reproduction, impressive bass response, and versatile installation options to elevate their in-car listening experience. One carbon-injected cones in the GTO 629 provide larger overall speaker-cone area than other cones in its class. On Count Basie's “Take the A Train,” the Bosendorfer grand piano sounds open and natural without much unwanted coloration.

Featuring a tweeter and a passive crossover, the JBL GTO629 ensures that sound is properly balanced and delivered to the listener. As a result, the GTO 629 is an excellent match for systems using head-unit or factory-amplifier power levels. Regular readers of my test reports know I prefer to audition new products in my listening room instead of in a car.You can also easily adjust the tweeter output from 0 to +3 decibels to compensate for low and off-axis mounting positions or road noise. What's not covered : Misuse, abuse, defacement, physical damage of any kind, and improper installation / operation. For a 6 1/2" speaker they have a nice mid bass and excelent highs (I set the button on the Tweeter to flat). Our Carbon-Compostie, non magentic frames maintain their integrity and precision even under thew most demanding conditions. The missing high frequencies are also confirmed by a small but significant drop in output between eight and 12 kHz as alluded to in my listening evaluations.
