Featuring 4 x 10" neodymium drivers and horn tweeter, the Ibanez Promethean bass speaker cabinet delivers plenty of bass tone to get the job done. The P410C speaker cabinet offers the most mid-range punch in the Promethean line. A bass reflection port on the back gives it a satisfyingly thick sound. Right out of the box, you'll find a balanced clarity from brilliant highs to the lowest bass ranges. 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.
