Designed specifically to provide powerful and accurate bass frequencies for sound reinforcement in a variety of enclosure types. The PD.1550/2’s improved linear excursion and efficient thermal path effectively dissipates heat minimising distortion and power compression effects.
The advanced magnetic assembly features a composite alloy and steel pole piece generating a uniform and stable magnetic field. The resulting high BL factor contributes to the speed, accuracy and fidelity of the PD.1550/2, maintaining control of the cone under the most demanding conditions.
