GENERAL DESCRIPTION
This low frequency transducer is specially intended for the most demanding applications. Its design concept arises from the
need of achieve a more resistant  loudspeaker that matches the more and more power given by ultimate amplification systems.
In order to accomplish that, almost every component of the speaker has been reconsidered: its voice coil has the benefits of an
improved manufacturing process, made with the highest quality materials and the diaphragm has been carefully developed to
give an extremely flat, smooth response. These characteristics make its integration in compact systems covering the low
frequency range a straightforward task.
Moreover, its parameters has been optimized to obtain an excellent bass response when used in small bass-reflex cabinets.
FREQUENCY RESPONSE AND DISTORTION CURVES                            FREE AIR IMPEDANCE CURVE
Note: on axis frequency response measured with loudspeaker standing
on infinite baffle in anechoic chamber, 1w @ 1m.
PREDICTED LOW FREQUENCY RESPONSE                              POWER COMPRESSION LOSSES
Note: Bass-reflex cabinet, Vb=30 l, fb=45 Hz
Note: These losses are calculated from a five minutes AES power test
applying band limited pink noise (25-1200 Hz). The loudspeaker is free-air
standing.
