GENERAL DESCRIPTION
This 15” bass loudspeaker has been specifically designed to deliver high impact bass response, with exceptional high power
handling capacity (750 WAES). It incorporates an edgewound copper ribbon voice coil (4.5” diameter) made with the highest
quality materials: high temperature magnet wire and polyimide fiber glass former. In order to achieve a reduced power
compression it features a massive vented magnetic structure. Moreover, an optimum cooling system based on a metal
intercooler allows a fast heat exchange and contributes too to the reduction of thermal power compression.
This model covers the low frequency range with smooth response, low harmonic distortion and high efficiency and it is mostly
recommended for high demanding subwoofer and woofer applications.
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=100 l, fb=50 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.
