The 560GTi 5-inch (130-millimeter) competition loudspeaker is a system that JBL® engineers built for competitors who won’t settle for anything less than superb sound on the road. They’ve designed the system with a list of breakthrough features that offer high-performance woofers and matching tweeters. To eliminate any potential distortion caused by the movement of air trapped within component parts, GTi Series competition speakers feature vented baskets, polepieces and voice-coil formers. An ultrarigid Kevlar® cone eliminates unwanted cone flexing – also called modal distortion – that can cause unpleasant-sounding peaks and dips in the midrange response. We’ve crafted the speaker’s spider and surround to ensure linear forward and backward motion, thereby further minimizing suspension-based distortion. A copper polepiece cap and flux-stabilization ring produce a linear voice-coil inductance that minimizes intermodulation distortion. To minimize other distortions, we’ve installed voice coil to ensure long enough to remain within the magnetic gap. The result is crystal-clear midrange, snappy mid-bass and an extremely smooth frequency response. If you want great sound in your car, the 560GTi is a great place to start.
