GENERAL DESCRIPTION
KEY FEATURES
This 15” model has been designed specifically to reinforce the low frequency range at very high power levels. The voice coil
diameter (4”) and its high stiffness cone give this loudspeaker an uncommon resistance to the most demanding requirements,
both thermal and mechanical. The voice coil has an optimised winding length to increase linear excursion, obtaining an Xmax of
7.5 mm. The magnetic structure construction generates a symmetrical magnetic field and, at the same time, provides an
efficient thermal path which contributes to heat dissipation. The SM 115/K has been designed for subwoofer and woofer
applications, specially for using in compact bass-reflex enclosures.
FREQUENCY RESPONSE AND DISTORTION CURVES
PREDICTED LOW FREQUENCY RESPONSE
Note: on axis frequency response measured with loudspeaker standing
on infinite baffle in anechoic chamber, 1w @ 1m.
Note: Bass-reflex cabinet, Vb=90 l, fb=45 Hz

POWER COMPRESSION LOSSES
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.
