Precision Devices PD.123ER - 12" 400W 8 Ohm

Perfectly suited to either direct radiating or popular horn loaded mid/high applications, the extended frequency range makes this unit an excellent choice where a small format high frequency unit dictates a higher crossover point than would be achievable with other, more conventional, 12" transducers.

A very popular choice for stage wedges when a faster mid-range attack is required. Also suitable for vocal performances as the PD.123ER covers the critical vocal range in a single, highly effective unit. Suitable for direct radiating or popular horn loaded mid/high applications.
