JBL CS742 2-Way 4" Coaxial Speakers

Frequency Response Up to 21kHz
Hear what you’ve been missing — the JBL CS7 Series offers a frequency response that delivers the full-range response associated with exceptional sound.

Plus One™ woofer cone architecture
Harman’s patented Plus One™ cones provide more overall speaker-cone area than other cones in its class — the result is higher sensitivity, increased low-frequency output, and greater musical character.

Individually Voiced
For most brands, off-the-shelf speakers and a cursory approval of frequency response curves are good enough. That’s not the case with JBL. We don’t only listen to our speakers against the competition — we voice them against each other to ensure each line has the consistent JBL sound signature that’s known and sought out by those who care about their audio.

Affordable Pricing
The JBL CS7 Series are all designed to give audio enthusiasts more boom for the buck — while they maintain a conservative price point, there is never a compromise in sound.

OEM-Level Reliability Testing
JBL tests every speaker design to the same rigid specifications as the automakers, subjecting them to extreme conditions that would break lesser speakers. We freeze them, bake them, shake them, blast them with ultraviolet light and drive them at full power for days to make sure your audio investment lasts for years.
High performance – for everybody
Club coaxial and component speakers bring legendary JBL sound to more vehicles. Their compact design means they’ll fit in most cars and trucks on the road, while high sensitivity delivers outstanding performance, even when they’re powered by factory stereos. Rugged polypropylene cones with the Plus One™ design deliver hard-hitting bass and long performance life. PEI balanced dome tweeters play smooth highs. Available in a range of standard sizes—3", 4", 5-1/4", 6", 6-1/2", 6" x 8" and 4" x 6" coaxial, 6" x 9" 3-way, and 5-1/4", 6-1/2", and 6" x 9" component—they’re the perfect upgrade from factory speakers.
