GR Bass AT 112H / AT 112H Plus Carbon Fiber 1x12 Bass Cabinets

GR Bass AT 112H / AT 112H+ Carbon Fiber 1x12 Bass Cabinets

The GR Bass AT 112H / AT 112H+ Carbon Fiber Bass Cabinets are lightweight passive 1x12 speaker cabinets designed for professional electric bass rigs. The AT 112H provides 350W RMS power handling, while the upgraded AT 112H+ increases capacity to 450W RMS, giving bassists two power options within the same compact AeroTech cabinet platform.

Both models combine a custom Jensen/Sica 12" woofer with a 1" horn driver and front bass-reflex enclosure. Their carbon-fiber construction keeps the cabinet manageable for rehearsals, touring, and live performances while maintaining the rigid enclosure structure required for controlled bass reproduction. A 38Hz-22kHz frequency range and 99dB sensitivity support extended low frequencies along with upper-frequency definition.

The GR Bass AT 112H and AT 112H+ connect to an external bass amplifier and are designed for players who want a lightweight passive cabinet rather than an integrated powered system. The AT 112H+ adds higher 450W RMS AES power handling and is available in 4-ohm or 8-ohm configurations, allowing the cabinet to fit different amplifier and multi-cabinet setups.
