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.
