For the last 23+ years the grill frames on my first JBL's have been straight and true. However, after a reconfiguration of my system two to three months ago they have begun to warp. Does anybody know of anything that can be done to restore them to their original state or at least prevent any further warpage?
Pics would certainly help here but most warpage is due to either moisture or direct sun exposure.
After 23 years of "Straight & True" performance, this would suggest your reconfiguration has placed them in harms way.
Some times they will go back to where they want to be and other times you can help them with reverse preasures and clamping but it is usually a long drawn out process. Don't know if we are talking about wood or plastic
here but suspect them to be wood and something is going on that needs correction.
