Suspension and Stacking Information PRIOR TO SUSPENDING OR STACKING ANY LOUDSPEAKER SYSTEMS, IT IS ESSENTIAL THAT THE USER BE FAMILIAR WITH OVERHEAD SUSPENSION AND STACKING TECHNIQUES, LOAD RATINGS, AND SAFETY CONSIDERATIONS. SUSPENSION The TRx series loudspeakers are fitted with captive 3/8"-16 threaded receptacles for suspension or permanent installation. Each captive nut has a WLL of 500 lbs. (226 kg.). Note: Working Load limits are based on vertical pull or 0°. For derating please see the derating notes below. DE-RATING: Using the mounting points at an angle will de-rate the "WLL" (working load limit) for each point. Each point mounted at an angle should be de-rated according to the following formula. "WLL"=cosine(angle) x 500 lbs angle = degrees form vertical pull 500 lbs = WLL for each TRx mounting point @ vertical pull WARNING - Never exceed the "WLL" throughout the suspension system. NOTICE: The user assumes liability for proper design, installation and use of rigging systems. IMPORTANT NOTE: All fly points of the TRx loudspeakers must be occupied with either the original hex screws provided or with mounting hardware (eyebolts). When the loudspeaker is suspended from one end, the load is transferred through the internal steel bracing to the hex screws in the adjacent wall of the enclosure for structural support. Also, if the holes are not "plugged" this will create air leaks compromising the low frequency performance of the enclosure. Re-check to be sure all hex screws and eyebolts are securely tightened.

OPTIONAL #TCSHK10 3/8"-16 forged steel eyebolt WLL=1600 lbs OPTIONAL #TCSHK58 5/8" forged steel shackle WLL=6500 lbs DANGER: 1) Hardware found at your local hardware store should not be used as it may not be rated for this application. 2) Mounting or rigging loudspeakers is a serious endeavor, always seek the advice of qualified experts. 3) Never use the handles for suspending the loudspeaker, they are not designed or rated for this purpose. 4) Improper installations may result in damage, injury or death. CAUTION: All hardware used for overhead suspension should be designed and used with a minimum 7:1 design factor. This is the ratio between the structural failure point and the loading to be applied to the component. Periodically inspect and maintain all rigging points on the loudspeaker and all suspension hardware. STACKING Ensure that the floor or stage is level and solid. Be cautious of outdoor windy conditions, speaker stacks could topple over in high wind conditions or be accidentally pushed or bumped over by crowds. Loudspeakers producing very high SPL (especially subwoofers) can shift from their original position. Ensure the feet of the loudspeakers are locked into the feet cups of the speaker below. SYSTEM SETUPS The TRx2000 series is designed to offer a large variety of options when configuring a system and can integrate with the TRx3000 series elements such as the TRx3903 column array, TRx3210A Line Array, TRx3018A or TRx3218 subs. As with any system, consideration should be made to match SPL of main and subwoofer cabinets. For instance use two TRx3018A or the dual Trx2218 to keep up with the SPL capability of a single TRx2153A or TRx2215A.
