JBL has released its new GTO Subwoofers that will consist of die-cast aluminum baskets, polypropylene cones, rubber surrounds, and a unique tinsel-wire protector that also strengthens the joint between the cone, the voice coil and the spider. The joint is the most important part since it must be strong enough to withstand more stress than any other point in the moving assembly, but JBL has all of it down pat. According to Michael Silber, director of product development for Harman Consumer Group’s Mobile, Portable and Companion Products division. “JBL woofers have to pass a 100-hour power test in which the RMS and peak power levels are tested simultaneously. When you see ‘300 watts, RMS’ and ‘1200 watts, peak’ in our ratings, you can be sure that those numbers are tested and verified. Additionally, to be sure the moving parts are robust, we subject every design to a proprietary mechanical power handling test at up to 17 times the RMS power-handling rating, which means these woofers have to survive test signals as high as 6000 watts. We’re fanatical about product quality.” The available models are :-
