PA, subwoofers and install speakers
JBL Professional covers everything from budget SRX boxes to large-format touring systems. Used SRX subwoofers are popular because parts are cheap and service is widely understood. The catch is that heavily used DJ cabinets are often re-coned with non-original kits, which changes both output and resale value. Always ask whether the drivers are original.
Confirm driver originality; re-coned cabinets are common and change the price materially.
