JBL CS790CHI Component Speaker

Product Overview

The JBL CS790CHI is a 6.5-inch (165mm) 2-way component speaker system engineered to replace dull factory speakers with signature JBL acoustic performance, powerful bass, and detailed high frequencies.

Patented Plus One Woofer Cone Technology

At the core of the CS790CHI mid-woofer is JBLs patented Plus One cone architecture. By extending the cone surface area up to 30% larger than standard cones of the same size, these speakers move more air, delivering deeper bass output and increased low-frequency efficiency without requiring a larger mounting hole.

Vented Motor Assemblies & Separate Tweeters

To handle continuous high volumes without thermal distortion, the woofers feature vented motor structures that dissipate heat effectively. Paired with separate high-frequency tweeters, the CS790CHI raises the soundstage to ear level on your dashboard or A-pillars, delivering crisp vocal clarity and detailed instrumentation.

Dedicated Outboard Crossovers

The kit includes custom external crossover networks that split audio signals with precision. By routing low and mid frequencies to the 6.5″ woofers and high frequencies to the tweeters, these crossovers keep high notes clean while protecting drivers from low-end overload.

Frequently Asked Questions (FAQ)

Q: What is the benefit of JBL’s Plus One woofer cone technology?

A: Plus One technology extends the cone area closer to the outer edge of the frame. This provides up to 30% more surface area than traditional 6.5″ cones, resulting in punchier mid-bass response and improved efficiency.

Q: Do I need an external power amplifier to run the JBL CS790CHI component speakers?

A: While these speakers run efficiently directly off a high-output factory or aftermarket head unit, pairing them with a 2-channel or 4-channel power amplifier (rated around 50W to 90W RMS) will unleash their full dynamic range and bass potential.

Q: Are crossovers included with this JBL component set?

A: Yes, the kit includes a pair of external crossover network modules that direct the correct frequencies to the 6.5″ mid-woofers and separate tweeters.

Q: Will these fit in standard 6.5-inch vehicle door speaker cutouts?

A: Yes, the 6.5-inch (165mm) mid-woofers feature standard 4-hole mounting patterns that fit into factory front or rear door cutouts, using standard mounting rings if needed.
