Port Perry, Ontario, Canada (November 17, 2005)–The Adamson T-21 Sub is a flyable and arrayable bass cabinet designed to provide sub-bass extension for Y-Axis true line-source systems and can be configured into an arc that will not shadow the mail line array. The T-21 Sub incorporates the newly developed Adamson Symmetrical Drive SD-21 Kevlar driver.
The double-spider design employs a balanced spider suspension with spiders at both ends of the 6-inch dual voice coil assembly and a neodymium magnet, resulting in stability under high excursions. T-21 Sub’s tuned enclosure is internally braced to minimize harmonics and distortion, its port geometry limits the occurrence of vortices and has therefore increased efficiency, lower turbulence and reduced compression at high SPL.
The T-21 includes AIR (Adamson Integrated Rigging) system captured flying hardware, with five precision rigging angles. Rear hinge allows for 110 degrees of rotational freedom during array assembly, and all heavy-duty linkage pins are attached to prevent lost pins during transport.
