TLA-121F - Dual 12" Two way Weatherproof Line Array Speaker


Dual 12" Two way Weatherproof Line Array Speaker

T-Line Weatherproof Line Array is composed by a dual 12" full range element TLA-121F and a suspend-able dual 15" subwoofer TLB-121F. Compact construction, light weight and quick installation makes the system most suitable for outdoor touring performance applications.

T-Line Weatherproof Line Array Speakers were designed in accordance with IP54 Standard, mainly be applicable for outdoor touring performance.

The adjacent speakers can achieve the seamless coupling and form the consistent cylindrical wave. The adjustable angle between two adjacent speakers is 0°-30°.

Magnetic circuit of LF is optimized through the finite element analysis to achieve the ultra-low distortion and maximum clarity under the high SPL. Overheated protection for drivers, perfect and reliable circuit protection.

TLA-121F adopts multifunctional structure design and Russian birch, weatherproof polyurethane painting provides super strong weather resistance.
