Haut-Parleur Beyma SM-108
[SM-108-8] Avis/Critiques 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-108 incorporates a 2” voice coil made with high quality materials: copper round wire with high temperature bonding strength and fiber glass former. Moreover, it features a powerful magnet system with rear air ventilation. By the other hand, its special surround guarantees the possibility of long displacements with linear behaviour. All these facts result in a 8” driver with extended and smooth low-mid frequency response, reduced harmonic distortion, good efficiency and excellent power handling (150 w AES). The SM-108 is specially recommended for woofer applications.
