The TMS-Low is a compact horn-loaded subwoofer enclosure consisting of an 18" low frequency driver. It is designed for use with the matching TMS-High mid/high enclosure, making a high output (129dB peak) full range portable sound reinforcement system. The birch plywood cabinet is shaped to allow the TMS-High enclosure to be stowed inside the horn flare when transporting the system in and out of a venue. It is fitted with heavy duty wheels and includes an integral pole mount socket to allow the mid/high to be mounted at the correct height.
