I have a rare JCM800 bass cab from the 1980's model 1553 serial 1729 and was wondering what the standard speakers where in this model. it's currently fitted with the x2 10" Celestion K10-70 cones and one 15" Celestion Sidewinder S15-250.
where could I buy replacements if one of them failed?
Regarding your JCM 800 1553, originally it was fitted with a 15" sidewinder, regarding the two 10" speakers we cannot say if these were original or not as data for these were not kept. The speakers to our knowledge are no longer avaliable.
