BassBoss AT312-MK3 Triple 12 inch Powered Top
The AT312-MK3 adds a third 12-inch neodymium driver working as a dedicated midrange to the AT212 platform, with a compression driver mounted co-axially through the midrange cone's pole piece for point-source integration across the band. 4,000 watts of Class D amplification is split three ways (2,400 W LF, 800 W MF, 800 W HF), holding 133 dB sustained and 139 dB peak from 60 Hz up through a conical 80 x 80 degree pattern.
The cabinet keeps the same rigging as the rest of the MK3 top line: four M10 fly points, a single 35mm pole socket, and Neutrik powerCON True1 for power in and pass-through out. DSP runs at 96kHz with eight onboard presets and up to a hundred more stored over ControlBASS via Ethernet.
