The TURBOSOUND TSW-218 is a horn-loaded double 18″ subwoofer incorporating Turbosound’s patented loading principles, designed for use in applications requiring accurate and powerful reproduction of low frequency energy at very high levels. Its ability to reproduce program material with such integrity makes the TSW-218 applicable for both fixed or mobile systems which require energetic low frequency response without stress or equalization. It is primarily intended for large scale concert touring and festival applications, although it is also ideally suited to large nightclubs that demand no-compromise audio quality.

The TSW-218 incorporates the TurboBass device, a patented design which employs a high-velocity partial horn-loading technique, giving precise cone control at high power levels. It addresses an increasing demand for accurate, high definition bass reproduction.

The TSW-218 is capable of outstanding electrical to acoustic power conversion (104dB at 1w/1m from a single unit). Optimization of the curved-profile laminated horn flare produces a dramatic increase in sensitivity when multiple units are coupled, with eight cabinets giving 110dB (1w @ 1m) output with flat frequency response down to 32Hz. For concert touring use the cabinet is fitted with heavy duty wheels to aid in handling and transportation. The cabinet is constructed from 3/4″ (18 mm) plywood, finished in black semi matt textured paint, and is equipped with recessed carrying handles, stacking feet, and side ratchet strap points for stable ground stacks.
