Outstanding audio performance with maximum versatility.

There are times when an installation calls for a separate woofer and tweeter, and there are other times when a coaxial is the better approach. With C3 Convertible Component Systems, the same product can be deployed in either configuration, delivering amazing sound quality in each application.

C3’s deploy JL Audio’s full suite of technology advancements to deliver unsurpassed value, performance and reliability. An advanced woofer frame design takes advantage of glass-reinforced polymer to permit better engineering of attachment points, leading to superior suspension geometry and lead wire management. Long woofer excursion capability with DMA-optimized performance delivers superb mid-bass and clean mid-range output, while the powerful 1-inch (25 mm) silk dome tweeter delivers brilliant high-frequency performance. Rounding out each package is a purpose-engineered, adjustable passive crossover network.

Compare the C3’s to any other component speaker system in their price class, and you will hear the results of all that technology.

Convertible Components

Sometimes a coaxial is the best solution... and sometimes you need to mount the tweeter separately. It’s great to have complete flexibility.
