Celestion Ditton 15XR

SPEAKER INFO
Model History
Celestion Ditton 15 were launched in 1966 and were one of the smallest speakers in Celestion’s offer (the smallest speaker in the offer was Ditton 10, shortly followed by County, Ditton 15, Ditton 44 Monitor, Ditton 25 and Ditton 66 Monitor).
Design
The Ditton 15 is a two way construction with 1″ dome tweeter, 8″ bass driver and 8″ passive radiator, housed in a relatively rigid, braced enclosure. There is a first order filter feeding the bass driver and a second order filter feeding the tweeter, so a fairly simple crossover setup.
From what I gathered, back in the day, these speakers offered very good value for money and sold in thousands in the late 60s and early 70s. According to the Internet sources, Celestion Ditton 15 were eagerly sought after by the stereo conscious public, and became the biggest selling bookshelf loudspeaker of its time.
