I am new to this forum so my apologies up front if I make any social blunders.
I acquired a pair of JBL L55s that I am restoring. I have some questions:
1) My speakers have metal glides on the bottom. Were these factory supplied or did someone add them? (photo attached)
2) One crossover board has a large black burn area (photo attached). Is it possible for a crossover to overheat or is this burn mark likely the result of carelessness from someone working on the board?
3) The tweeters aren't original (brand unknown) and I would like to find LE20-1 tweeters. Are these tweeters any good or should I look for something better? I prefer original where practical but if the sound is bad then upgrade. Also, does anyone have a photo or specs of the original tweeter mounting screws in regards to size and appearance?
Thanks
