Dayton Audio ND91-8

Full-range speaker 8 ohm 10.35 cm

Dayton Audio Speaker ND91-8 medium wide strip

The ND91-8 is a full-range speaker featuring a low distortion motor mounted on a ferrite magnet . With a wide frequency response (65Hz - 17kHz),  well-defined bass impact and low distortion, it is an excellent compromise for any simple modification / repair project. 

Driver design adress both power and precision requirement  thanks to a sophisticated design involving a structure copper alloy ring and a underhung coil, allowing increased linearity in movement within the magnetic field.

30 watts (RMS) of power with a 5.1 mm excursion (XMax) in small dimensions (103 x 60.8 cm) make this loudspeaker a balanced and versatile system that can be used both in a single enclosure assembly as in more complex project ( such as line-arrays ...)
