I have a pair of these that have been sitting dorment here in their original Eaton cabs for the longest time.....the issue on one driver is as follows....
Low to medium volume all is perfect,great sound top to bottom no problem.....turn it up a bit more and suddenly in the 1khz area the one speaker distorts but only at this specific frequency.....everything else remains perfectly normal.....it is not the crossovers which I immediately suspected as the midbass to tweeter crossover point is at 1khz,I switched them and the fault travelled with the speaker......I have attempted some realignment of the tweeter etc but no luck....
Paper spacers take up the magnet gap and I was wondering if over tightening or one or two having been removed in the past could perhaps cause this?.....not saying the spacers have been removed in the past but just trying to work this mystery out.

Any help appreciated.thanks
