KEY FEATURES
•      High power handling (500 w AES)
•   4” (100 mm) copper round wire voice coil
•   Excellent sensitivity: 98 dB
•   Large Xmax: 7.5 mm.
•   Extremely low resonant frequency: 27 Hz
•   Designed for subwoofer and woofer applications
GENERAL DESCRIPTION
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.
