Voice coils

yes try this site if not seartch for speaker repair kits .http://www.mwaspeakerparts.com/

Hello. I do speaker reconing and amp rebuilds for a living and the L7's often suffer from tinsel leed wire breakage which can cause "poping" and "screaching" noises in the sub in various cone positions. You need to remove the sub and push straight down on the cone repeatly and determine if you can feel or hear crunching noises to make sure the voice coil and/or spider are not damaged. A faulty leed wire can usually be identified by a dark spot or obvious breakage. All of the L5 and L7 models can be successfully repaired as long as they are the older models that have a center cap in the cone. The newer capless models will have to have an upper brace cap glued to all of the cone's fingers and will have a rather ugly appearance. Leed wire overhauls usually run around $30.00 for the older models. Voice coil and spider overhauls run around $90.00.
