SB-218 is a horn-loaded subwoofer system that offers a very high performance when compared to its size. Mounts two 18-inch long excursion transducers and is surprising for its small size and the clarity of its sound. With 2800 W AES and 144 dB-peak, it is an excellent option for sound reinforcement in large affluence of public applications.
The system is made with baltic phenolic birch plywood and all necessary reinforcements, resulting in a surprisingly clean response and mechanical noise free. Each unit incorporates slots that allow stacking units easely. In addition, it is possible to incorporate on demand NL4 connectors on the front to facilitate cardioid configurations.
SB-218H are the same product but incorporating the flying hardware manufactured with the highest quality and maximum strength steel.
