Precision Devices PD.154-4 - 15" 500W 4 Ohm
Designed as an extremely powerful low frequency transducer for bass and compact sub 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 radiating systems in which the powerful bass response comes into its own.
