The TS212 is a dual 12 inch, ultra-compact, direct radiating subwoofer that is designed to provide impressive low frequency impact and solid musicality. Its 4 inch voice coils, strong neodymium magnets, and innovative low-turbulence ports permit an optimal tuning to be achieved in an enclosure that is unusually small for a dual 12 inch subwoofer. Eight handles facilitate transport of the enclosure in portable applications. A threaded, 20 mm connector plate is centered on the TS212’s top panel for use with the optional, height-adjustable SP1 Speaker Pole. This pole’s M20 threaded bolt screws securely into the connector plate and is used to mount loudspeakers equipped with a 35 mm / 1.38 inch pole socket directly above the TS212. Four vibration isolation feet prevent spurious vibrations and “walking”. When stacking enclosures, the vibration isolators nest in recesses in the enclosure below. The recesses are configured so that enclosures can be rotated to create cardioid arrays. The input is mounted on a chamfer at the rear of the enclosure, allowing cable access without requiring additional space between the enclosure and a wall or stage. The TS212 provides big subwoofer sound in a package that one person can easily transport, and its low profi le allows it to fit into out-of-the-way places. The combination of high performance, labor saving portability, and aesthetic appeal represents an ideal solution for corporate A/V, television/radio productions, theatrical productions, nightclub PA, portable DJ systems, and more.
