Speaker Driver Full Range 30W 8 Ohm 85.6dB 80Hz-20kHz Ø7.6cm
The Dayton Audio PC83-8 is a wide-range loudspeaker using a braided glass fibre membrane, rubber suspension and a powerful motor. The addition of a copper cover on the pole allows better membrane control, lower inductance and reduces distortion for improved high frequency response. Offering very good performance over a wide frequency range, a controlled off-axis response and high efficiency, the restitution is impressive for such a small speaker size.
