TOA's Type C line array speaker system is based on the company's phase wavefront control technology, featuring a choice of 15° or 5° vertical dispersion angle modules, with a 15" subwoofer enclosure for low-end reinforcement. Modules can be combined when both short- and long-throw coverage is required, while all three enclosures are also available in IPX4-rated splash-proof versions. The mid-high modules use proprietary Sync-Drive™ waveguide design and can run in either single or bi-amplified modes. A wide variety of optional mounting brackets is available, and LF and HF drivers can be replaced from the rear of the enclosure, if necessary. For applications that require greater output and low frequency sound enhancement, a two-way multi-amplifier driven speaker system featuring a 30cm low frequency driver and two compression drivers is also available.
