Turbosound TQ12 12" Two-Way Passive Installation Loudspeaker
The TQ12 is the 12" cabinet in the Turbosound TQ line, a two-way passive system that trades size for output when the room needs more headroom than a 10" box has. It is voiced to run on Lab.gruppen loudspeaker management and shares the line's preset library.
A single neodymium low frequency driver and a 1.4" neodymium compression driver sit on a rotatable 80 x 30 degree exponential horn with the dendritic plane wave transformer waveguide, crossed over passively inside a reflex-loaded plywood enclosure. The rear plate carries two twist-lock connectors for input and link, the cabinet takes a dual 35 mm pole socket, and threaded rigging points accept the yoke and swivel brackets sold separately. Lab.gruppen PLM+ presets and EASE GLL data are published for the series.
