I made a deal for a pair of LE-15As in very good cosmetic condition. I assumed they were fine as per the seller saying so. I unboxed them and looked them over. They made the trip. However there is much cracking in the Lansalloy surrounds. When I pushed on the cone to check for rubbing, there is no movement at all - totally stiff! This can't be normal can it? I am getting readings of continuity on both drivers. Need some advice before I get upset. I gave a good bit for these and the seller seems very decent. Maybe I just don't know how LE-15As are? HELP!
