GTO609C

Three-ohm voice coils

Three-ohm voice coils in the JBL GTO 609C compensate for the added resistance by thin factory-installed speaker wiring. They also provide more output than factory-installed speakers of the same class.

Vented magnet assemblies

The JBL GTO 609C speakers feature vented magnet assemblies on the woofer/midrange driver to help cool the voice coil. Keeping the voice coil cool adds to increased reliability from greater power handling and helps eliminate power compression that can distort the speakers’ sound.

Frequency response up to 21kHz

A wide frequency response that extends beyond 20kHz helps compensate for speaker-placement variations in your car and for human hearing deficiencies in the high-frequency spectrum above 15kHz. The result is that the JBL GTO 609C’s 3/4-inch (19-millimetre) component tweeters deliver the full-range frequency response that you associate with great sound.
