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

Ultrarigid Kevlar-Woofer Cone - In designing the 660GTi woofers, JBL engineers have left no stone unturned. The basket, polepiece and voice coil former all include vents to eliminate any potential distortion caused by the movement of air trapped within these parts. The ultra- rigid Kevlar® cone eliminates unwanted cone flexing (also called modal distortion), which can cause big peaks and dips in the midrange response. The spider and surround are designed to ensure linear forward and rearward motion, minimizing distortion caused by the speaker’s suspension. The motor includes a copper pole- piece cap and a flux stabilization ring that work together to produce a linear voice coil inductance that minimizes intermodulation distortion. Finally, an extralong voice coil ensures that the coil remains in the magnetic gap to minimize distortion at low frequencies and their harmonics, and during high-output transients. The result is crystal-clear midrange, snappy mid-bass without any audible ringing or hang-over, and a smooth frequency response that needs no compensation circuitry in the crossover.

Rated 5 out of 5 by from Simply Fantastic!!! Absolutely nothing comes close to these speakers. Clean, clear, power; at any volume. Once you hear these speakers, you can never go back to any thing else. Worth every penny!!!!!!!!! Hears a rumor that they would be discontinued. That would be tragic!

Asked by: saleh
The materials used in the 660GTI do not deteriorate over time. They will not suffer any lack of sonic quality due to the date they were built vs. the purchase date.
