The SRX715 offers the highest level of performance available from a portable, pole or tripod mountable speaker. The 15", 2-way, bass-reflex JBL SRX715 2-Way Speaker Cabinet is ideal for sound reinforcement, live performance, music playback, or speech. The Differential Drive woofer handles 800W RMS, while the 3" diaphragm, neodymium compression driver on a 75 x 50 horn produces clean, clear highs. Constructed of top quality birch plywood and coated in JBL's rugged DuraFlex finish, so you know the SRX715 is built to last. Internal braces and bulkheads reduce acoustic losses caused by panel resonance. Add a SRX718S (not included) for increased low-frequency extension.
