15XA38Nd

This 15" coaxial loudspeaker is intended for the most demanding professional applications. Its low frequency unit features a 4" (100 mm) edgewound aluminium ribbon voice coil capable of handle 350 w AES. This bass unit has been optimized in order to fit in with the most compact bass-reflex systems. The high frequency unit uses a 2.8" (72.2 mm) aluminium ribbon voice coil and a composite structure diaphragm, that is to say, a titanium dome and polyester surround combination. All these components give as a result a coherent and extended frequency response with low distortion that ranges from 25 Hz up to 20 kHz. Moreover, the use of a common neodymium magnet system for both units reduces the weight to 6.8 kg.
