The reason for the use of multiple 10 inch drivers instead of the traditional 12 or 15 inch driver, was the clever exploitation of acoustical characteristics. The 10 inch driver has a resonant frequency above the fundamental of any of the strings on a four or five string bass. by using a sealed cabinet containing four groups with two tens in each, even smooth low end response is achieved. this also provides substantial acoustical output and power handling capacity.
