Speaker Repair “No No”: What Not To Do

When you recone a speaker you must set the spider and cone level. In our speaker reconing instructions, we advise that you gently turn the spider once it is in place to insure it returns to level. Someone obviously missed the memo while reconing this Electro-Voice EVX180. As you can see the spider is not level. Sunken spider causes the voice coil to be set too low which results in minimum excursion and often breaking of the bottom of the voice coil former. In this case, it also caused the voice coil to cone bond to break. No worries though. We will use genuine EV replacement parts and work our magic!
