Moisture can damage the speaker cone and surround and cause corrosion of electrical contacts and metal parts. Avoid exposing the speakers to direct moisture. Keep speakers out of extended or intense direct sunlight. The driver suspension will prematurely dry out and finished surfaces may be degraded by long-term exposure to intense ultra-violet (UV) light. MRX500 speakers can generate considerable energy. When placed on a slippery surface such as polished wood or linoleum, the speaker may move due to its acoustical energy output. Precautions should be taken to assure that the speaker does not fall off a stage or table on which it is placed. 60 Hz - 20 kHz 90 Hz - 20 kHz 70º x 70º nominal Passive 1. 7 kHz 400 W / 800 W / 1600 W, 2 hrs1 350 W / 700 W / 1400 W, 100 hrs1 123 dB SPL continuous (129 dB SPL peak)2 97 dB SPL 1 x JBL 262H 305 mm (12 in) Differential Drive® woofer 1 x JBL 2408H 37. 5 mm (1. 5 in) annular polymer diaphragm, neodymium compression driver 8 ohms Symmetrical stage monitor, 15/18 mm, plywood.

However, all speaker finishes are subject to damage. Should the DuraFlex finish require repair, a touchup kit (Part Number 16677) is available from JBL Professional Parts. Single Box On Pole Coverage The dual angle pole socket on the MRX512M and MRX515 provides flexibility in aiming the speaker. As a general rule, the speaker should be positioned so that the audience cannot see the top or bottom panels of the speaker. When using stands or poles, be sure to observe the following precautions: · Check the stand or pole specification to be certain the device is designed to support the weight of the speaker. Observe all safety precautions specified by the manufacturer. · Be certain that the surface on which the system is to be stackedis flat, stable and solid. · Route cables so that performers, production crew and audience will not trip and topple the speakers. · Inspect the stand (or pole and assorted hardware) before each use and do not use equipment with worn, damaged or missing parts. · Always be cautious when deploying the system outdoors.
