The coil is dunked in a laquer to prevent the windings from slipping as the speaker moves in and out. If the speaker has a 'seized coil' then it has generally been overpowered at some point in its life and the laquer has melted and sometimes some of the windings will slip down the former. This stops the speaker from moving in and out smoothly and poor performance and sound quality will be heard. In anticipation of the obvious question, no you can't - it'll need a recone Quote Link to comment Share on other sites More sharing options...
