JBL Car GTO 609C 6.5 Inch 2 Way Component Speaker System Including x2 Midrange Speakers and Tweeters Black

Advanced FRP frames are nonmagnetic to transfer more energy to the voice coil, and the nonresonant property improves overall sound quality. Carbon-injected Plus One cones deliver more diaphragm area than other speakers in the class. The carbon material is light while still maintaining stiffness to perform well with rapid cone movement. Frequency response up to 21kHz means a bright, airy sound that opens up the listening space Vented magnet assemblies keep the voice coil cool and reduce power compression over time Three-ohm voice coils help compensate for added resistance in thin-gauge factory speaker wire. Compatible with all 4 ohm-rated amplifiers and head units.
