GR Bass AT 212 Slim / AT 212 Slim+ Carbon Fiber Bass Cabinets - 700 Watt

GR Bass AT 212 Slim / AT 212 Slim+ 2x12 Carbon Fiber Bass Cabinets

The GR Bass AT 212 Slim / AT 212 Slim+ Bass Cabinets are passive 2x12 carbon-fiber speaker cabinets offered in 700W and 900W RMS configurations. Both models combine two custom 12" Jensen/Sica woofers with a 1" horn driver, delivering a 35Hz-22kHz frequency response and 103dB sensitivity in a narrow vertical enclosure.

Choose the AT 212 Slim for 700W RMS AES power handling or the AT 212 Slim+ for an increased 900W RMS rating. Both versions are available in separately ordered 4-ohm or 8-ohm configurations, making them adaptable to different bass amplifier and multi-cabinet setups. Rear bass-reflex ports help preserve the cabinet's slim front profile while supporting low-frequency output.

The AeroTech carbon-fiber enclosure keeps these dual-12" cabinets comparatively lightweight for rehearsals, touring, and live performance. Both models share the same 15.4" wide, 14" deep, and 30.1" high cabinet dimensions. The horn driver provides an on/off control plus a three-position level selector, allowing players to tailor high-frequency output for different instruments, rooms, and amplification systems.
