JBL Club 605CSQ 6.5″ Two-Way Component Speaker System

Woofers built for sound quality

Each 6.5-inch (160 mm) woofer uses a carbon fiber cone with JBL’s patented Plus One design, which extends the cone area for its size to move more air and add bass. A Y40 ferrite magnet helps raise sensitivity to 93 dB at 2.83 V, so the set plays with authority even on modest power. Power handling is 95 watts RMS and 285 watts peak, with a 48 Hz to 21 kHz frequency response.

Smooth, adjustable highs

The edge-driven silk dome tweeters are designed for a broad, smooth top end that stays easy to listen to at higher volume. Each external crossover splits the signal at 5 kHz and has a switch to set tweeter output at 0 dB or +3 dB, so you can compensate for a tweeter mounted low in the door or high on the dash.

Tweeter mounting options

JBL’s I-Mount kit includes flush-mount and surface-mount cups. Flush mounting needs a 1-3/4-inch cutout and 1 inch of depth, and the tweeter can be angled up to ±40 degrees. The Starfish adapter, with six break-off tabs, lets you place the tweeter behind a factory grille or in an A-pillar. Locknuts hold everything in place, and a tweeter can be serviced without removing the whole assembly.

Installation notes

The 3-ohm nominal impedance draws a little more power from many head units. Grilles, multi-hole adapter rings, a foam gasket, and mounting hardware come in the box. Per JBL’s installation drawing, the woofer needs about 51.5 mm (2.03 in) of mounting depth.
