SM115/N SM115/N S M S e r i e s 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. 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.
