    KEY FEATURES
    •   High power handling (400 w AES)
    •   3” (77 mm) copper voice coil with apical former
    •   Optimum winding length for increased linear
    excursion
    •   Extended response in the medium frequency range
    •      Designed for high power woofer applications
    GENERAL DESCRIPTION
    The design concept of this low frequency transducer 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. The SM-115/N incorporates a 3” voice coil made with high quality materials: copper round wire
    with high temperature bonding strength and apical former. Moreover, it features a powerful magnet system with rear air
    ventilation. All these facts result in a 15” driver with extended and smooth low-mid frequency response, reduced harmonic
    distortion, good efficiency and excellent power handling (400 w AES). The SM-115/N is specially recommended for woofer
    applications.

    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.
