The ProX XS-SP292922W is purpose-built for touring sound engineers and rental houses managing high-output line array subwoofer systems. This universal case accommodates RCF SUB 8004-AS, RCF SUB 9004-AS, and comparable single-unit subs that demand serious road protection without custom fabrication cost or lead time.

Laminated 3/8" plywood construction with impact-resistant foam lining shields your investment through load-in chaos, truck bed shifting, and airport handling. The ATA-300 rating means it meets airline standards for equipment transport, critical when your show depends on gear arrival. Whether you're running monitor systems, main arrays, or mid-field fill, this case locks down speaker security so you focus on mix, not logistics.
