Speaker Driver Midbass Aluminium 30W 8 Ohm 83dB 60Hz - 10kHz Ø10.2cm
The Dayton Audio ND105-8 low-frequency midrange driver incorporates a rigid and extremely lightweight aluminium diaphragm, capable of significant linear excursion for such a compact size. A balanced Neodymium motor effectively limits distortion. The combination of these two technologies makes it possible to obtain a loudspeaker with an impressive sound reproduction due to its dynamism.
