ATHENS TCS218B-WH

The 6,400-Watt TCS218B-WH is a high performance dual 18" subwoofer system designed for a wide range of speech and music sound reinforcement applications. Engineered to work in conjunction with Turbosound loudspeaker management systems, the TCS218B-WH provides extended FOH low frequency performance. A bass reflex port design enclosure, the TCS218B-WH features two high power, double suspension 18" low frequency drivers with a specialised voice coil wound on both the inside and outside of the coil former for higher magnetic density, heat dissipation, higher power handling capacity, and improved efficiency. The TCS218B-WH subwoofer provides fast and accurate transient response for virtually distortion-free operation – even in the most demanding performances.   Finished in a durable semi matt white paint, the cabinet is constructed from 18 mm (3⁄4") birch plywood – and includes a rugged powder coated perforated steel mesh grille backed with reticulated foam. Internal M10 threaded rigging points are provided, and the rear panel connector plate carries industry-standard twist-lock speaker and barrier strip connectors for input and link connections to additional enclosures.  

Architecture & Engineering Specifications

The speaker shall be of the passive subwoofer type consisting of two 18" (460 mm) LF drivers, switchable to parallel or discrete operation. Performance specifications of a typical production unit shall meet or exceed the following: frequency response, measured with swept sine wave input, shall be flat within ±3 dB from 33 Hz to 200 Hz and within -10 dB from 27 Hz to 200 Hz. Nominal dispersion shall be “half space.” Nominal impedance shall be LF parallel: 4 Ohms, LF discrete: 8 Ohms x 2. Power handling shall be 1,600 Watts continuous, 6,400 Watts peak. Sensitivity, measured on axis, mean averaged over stated bandwidth, shall be 99 dB, 1 Watt @ 1 metre. Maximum SPL (peak), measured at 1 metre with music program at stated amplifier input, shall be 137 dB. Dimensions: 710 mm high x 1130 mm wide x 730 mm deep (28.0" x 44.5" x 28.8"). Net weight: 93.5 kg (205.7 lbs). The loudspeaker system shall be the Turbosound TCS218B-WH. No other loudspeaker shall be acceptable unless submitted data from an independent test laboratory verifies that the above combined performance / size specifications are equaled or exceeded.
