The Celestion Ditton 66 is an iconic British speaker. Broad frequency response. Wide dispersion. Extremely low distortion in bass and mid-range at normal listening levels. Its high efficiency (only 4.8 watts input required for 90 dB with pink noise signal) and high power handling capacity result in extremely wide dynamic range. High frequencies are handled by the HF2000 tweeter (specified by the BBC. for monitor use). Becoming increasingly difficult to come across.
