Specification :

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.

- High power handling ( 400 w AES)
- 3� ( 77 mm) copper voice coil with apical former
