Context

The Celestion Ditton 100 was released during a period when British loudspeaker designs were gaining recognition in international markets. While Celestion produced other models in the Ditton series, such as the Ditton 15, 25, 33, and 66, the placement of the Ditton 100 within the lineup is not explicitly documented. It was noted as one of the more affordable options among UK-designed speakers entering the US market in the early 1980s.
