The TRC Series offers outstanding full-range, 50 Hz to 18 kHz performance for surprisingly compact 2-way loudspeaker systems. The TRC121/9K offers 90° by 60° coverage while the TRC121/12K has wide-angle 120° by 60° dispersion. All models feature a unique multi-angle cabinet design and the revolutionary new Renkus-Heinz Complex Conic waveguide technology. The unique design of these horns allows them to be rotated 90° within the cabinet and permits horizontal loudspeaker mounting in low ceiling applications.
