This is the JBL sound system from the 500 series. The system is 4 of the JBL PRX 525 tops that contain 2 -15" woofers and a high. The built in cross-over allows the bottom speaker to act like a sub and the top as a mid.

The subs are the JBL MPro 418 which consist of a single 18" subwoofer that powers another non-powered subwoofer. This system also has 4 of these per side.

This system will power a mid-size field, gymnasium and most hotel ballrooms.
