660GTi

6" (160mm), 600W dual-component competition speaker system with crossover.

JBL® engineers designed the 660GTi 6-inch (160-millimetre) competition speaker system with a list of breakthrough features that offer high-performance car audio woofers and matching tweeters. Its speaker’s feature vented baskets, pole pieces and voice-coil formers to eliminate any potential distortion caused by the movement of air trapped within component parts. An ultra-rigid Kevlar® cone eliminates unwanted cone flexing – also called modal distortion – that can cause unpleasant-sounding peaks and dips in the mid-range response. The speaker’s spider and surround ensure linear forward and backward motion to minimise suspension-based distortion. A copper pole piece cap and flux-stabilisation ring produce a linear voice-coil inductance that minimises inter-modulation distortion. Finally, the speaker’s voice coil is long enough to remain within the magnetic gap in order to minimise other distortions. The result is crystal-clear mid-range, snappy mid-bass and an extremely smooth frequency response. JBL engineers designed this speaker for optimum performance and targeted it at competitors who won’t settle for anything less than great sound on the road.
