| Description: |
|
|
Designed specifically to provide powerful sub bass frequencies with minimal distortion and power compression. The PD.2450 offers a fast responsive sound and is an outstanding drive unit, suitable for sound reinforcement in a variety of enclosure types since it allows designers considerably more freedom with enclosure design and specialised loading techniques without having to allow for physical characteristics or power handling limitations which are typically the result of more traditional designs.
Perfectly at home in new or refurbished horn loaded sub bass systems this unit also delivers powerful lows in reflex designs, such as home theatre and house of worship applications.
*1 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 PD.2450 may significantly exceed that of other manufacturers with high published power ratings.
*2 Distortion is measured at 10% of the rated power (AES Standard). |
