PD.154

• Heavy duty 15” cast aluminium frame with extra wide flange for increased rigidity

• Woofer

• Field replaceable magnet for touring applications

• 500W RMS

• 4” copper voice coil assembly

• 125 oz. ceramic magnet

• A B/L in excess of 29 T/m for fast accurate lows

PD.154

Designed as an extremely powerful low frequency transducer for bass and compact bass applications.

Equally at home in drum fill and stage monitor wedges where exceptional low frequency performance makes the PD.154 an ideal choice. Also suitable for bass guitar applications.

Ideal for three-way direct radiating systems in which the powerful bass response comes into its own.
