I have a set of JBL Sovereigns and the spec sheet says efficiency is 82db at 15'
i'm trying to compare them to a restored pair of Quad ESL57 which have a db rating of 87 @1m/1w
so the issue that i'm trying to determine is this...
i believe my quads to be needing rebuild, as they are significantly quieter than the JBLs- i just really have no way of knowing.... they are from 1979 and completely original - so i trust that new power supply boards and reconditioned panels would increase output some - just not sure how much and if its worth the reconditioning price.
any help on the loss of db per foot - would be helpful.
thanks
