Type 3-way coaxial loudspeaker › See more product details; Product description Premium class car speakers. The JBL GTO series of exceptional sounding car hi-fi speakers incorporates innovative technologies specially developed for the demanding environmental conditions in modern cars. With the patented Plus One woofer diaphragm technology and robust manufacturing materials such as For example, carbon composite frames, butyl rubber bezels, fabric dome tweeter membranes and UniPivot (US Patent No: 6,002,780) tweeter positioning on selected coaxial models and the I-Mount (USA Patent No. 5,859,917) system for tweeters in the component parts are the car speakers of the GG TOTOseries the ideal on TOrating for any car hi-fi system. The GTO 939 series coaxial speakers have been designed by JBL engineers to produce a powerful, clear sound from a main unit or amplifier capable of delivering a whopping 300 watts. This makes the GTO 939 an ideal addition to systems with a main unit or factory set power levels of the amplifier. It is also suitable for many GTO series amplifier combinations with one or more woofer(s). And its great rating increases its reliability over the life of the speaker. JBL GTO 939 at a glance: 6 x 9 inch 3-way coaxial speakers (150 x 230 mm oval). Maximum load: 300 W. Average continuous power: 100 W RMS. Recommended RMS power of the amplifier: 5 W to 200 W. Frequency range: 46Hz - 21,000Hz Nominal impedance: 3 ohms. Sensitivity (2.83V/1m): 94dB. Plus-One low-frequency membrane made of fabric with carbon reinforcement with larger diaphragm area than competitors Precise fabric dome tweeter with external voice coil (edgde-driven) and a super tweeter. Non-magnetic carbon composite speaker basket Variable tweeter level adjustment via a switch on the front (0db/+3dB) Ventilated drive for better heat dissipation and higher load capacity. Installation dimensions: cut-out 219 mm x 149 mm; installation depth 71 mm. Conventional beads lose a lot of membrane surface due to their attachment. Plus-One gains significantly thanks to the attachment to the outermost edge. Highlights for the perfect sound. Patented Plus-One Mebrante technology The GTO 939's Plus One carbon reinforced diaphragms offer a larger overall speaker diaphragm area than other diaphragms in its class. With an effective magnification of the membrane surface, the speaker moves more air. In addition, its carbon-reinforced membrane material creates a lighter and stiffer membrane. The result is better low frequency behavior and an improved ability to reproduce those important musical notes often associated with larger speakers. The reduced impedance of the voice coil results in the ideal impedance of 4 ohms in total with cables and connectors. True 4 ohm construction. Reduced impedance for improved sensitivity In the field of original equipment of automobiles, many manufacturers already rely on the low-impedance principle of loudspeakers that you will also find in the JBL GTO series.
