PD125 Spec Sheet (Acrobat PDF file)

The PD125 Precision Directivity™ loudspeaker is a high power low frequency module designed for use in arrays and in conjunction with other PD series systems to construct fullrange systems.

The PD125 employs the 2226H 15"
transducer, one of JBL’s family of
Vented Gap Cooling woofers.
Transducers are mounted “magnetsout” for maximum heat transfer, assuring long term reliability at high power levels. Each transducer is mounted in a separate vented subchamber.
