Its composite cabinet features a computer-modelled internal ribbing design that increases overall cabinet rigidity, which improves acoustic performance and durability. Like with every JBL product, everything is reinforced by industry-leading test and validation protocols.

These were part of a bigger system, including PRX800 units and SRX800. I personally think the PRX600s have the best sound out of all three series. The 618xlfs drive a punchy thump and adding a better mid range kick and coupled with the deeper lower hz of an 828sp or 2x 818xlf, was great for reinforcing a bigger or outdoor space.
