It's no secret that Class D power supplies have made great sounding portable bass amplifiers a reality. Italy-based GR Audio has upped the ante of portability and sound quality with their line of AT Cube Carbon Fiber bass amplifiers. Weighing in at only 20 pounds, the GR Bass AT Cube 800 puts out 450W into a single 12" SICA Neodymium speaker and 1" horn driver. With its extremely stiff Carbon Fiber ported enclosure, all the sound engery goes into the music, not flexing the enclosure. The result is excellent efficiency and responsiveness. 

But the GR AT Cube 800 is more than just space-age materials. The fully featured control panel sports  both gain and master volume controls, 4-band EQ with selectable midpoints, and bright and deep switches. Convenience features include headphone output, aux input, DI output with variable level, built in tuner, effects loop, and extension speaker output. Driving an additional 8 ohm enclosure the AT Cube 800 puts out 800 watts into 8 ohms (see attached photos for control details).

But most of all the AT Cube 800 is flexible, portable bass power with the tone shaping capabilities to fit any gigging or studio situation. Going on the road -- and sounding good - has never been easier.
