The TTL31-A II Active Compact Line Array Module from RCF is a full-range compact wide-dispersion line array. The TTL31-A II is a two-way active system featuring a 1 x 8" neodymium woofer with a 64mm voice coil in horn-loaded configuration, and a 3 x 1" neodymium compression driver with a 37mm titanium dome voice coil in horn-array configuration. The woofer provides large excursion, light weight, and a high BL for vocal presence.
The compression driver design offers minimum spacing between throats to avoid HF cancellation. The TTL31-A II amplifier has DSP controlled multiway digital amplification. The cabinet is in marine Baltic birch plywood, coated with high-resistance epoxy paint. The mechanical suspension & orientation system is made of high quality steel, and is precise and easy to use. The suspension system is directly connected to the aluminum sides of the cabinet.
