Thiele - Small Parameters PD.153 ER Combining excellent bass performance with the advantage of an extended, very fast mid range frequency response, the PD.153ER is an excellent choice where a small format high frequency unit dictates a higher crossover point than can be achieved with other, more conventional, 15” transducers. A popular choice for stage wedges when a faster mid range attack is required. Also suitable for bass guitar.
