Combining excellent bass performance with the advantage of an extended, very fast mid range frequency response, the PD.153ER/2 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-inch transducers.

A popular choice for stage wedges where a faster mid range attack is required. The PD.153ER/2 is also well suited to bass guitar applications.

* Power compression is the reduction of sensitivity at the specified power. Higher power ratings do not necessarily give a proportionate increase in SPL therefore the maximum SPL of the driver may significantly exceed that of other manufacturers with high power ratings.
** Distortion is measured at 10% of the rated power (AES Standard).
1. AES Standard (50 to 500 Hz). Program 800 Watts.
2. AES Recommended Practice.
3. Thiele - Small Parameters follow a 400 Watt preconditioning period verified by Klippel LSI measurement.
4. 2.83V. Half space response measured in a 975 Litre sealed enclosure.
Please note that frequency response measurements are supplied for comparison purposes only and are not a measure of the low frequency performance which may be achievable in a fully optimised system.
