Featuring a 1 x 15" neodymium driver and horn tweeter, the 300W Ibanez Promethean bass cabinet delivers plenty of full-range bass tone to get the job done. The big 15" speaker provides a powerful bottom and the horn tweeter adds the clarity and brilliant highs. It also can get very, very loud. The Promethean series cabinet is designed to have the portability needed by working musicians who travel around from one venue to the next.
