Very high efficiency and low distortion are special features of this mid-bass transducer.
Special treatments are applied to cone surface and surround for optimum dampening.
Applications
The L12P300 is specially designed for compact size bass reflex enclosures. The unique combination of short voice coil and very high BL/Re ratio makes the L12P300 a very good choice when fast and precise mid-bass reproduction is required. Very good for high power horn loaded applications.
