Celestion Ditton 22 loudspeakers—a classic 3-way sealed design from the late 1970s—is one of the most rewarding vintage audio projects. Known for their warm British voicing, rich midrange, and smooth high frequencies, bringing a set back to factory specification (or better) primarily comes down to four main restoration stages.

The Missing Component
When servicing vintage Celestion drivers, it is important to note that original factory technical specifications for many of these components were never published.
As a high-volume manufacturer during this era, Celestion’s production model was optimized for large-scale original equipment supply cycles. Consequently, the company did not prioritize the release of public technical data sheets or third-party component-level repair support for its legacy driver range.
We do not offer a replacement for the bass drive units.
