Well. I am so pissed off. I got a pair in Ebay for $800.00 free shipping. The guy told me they were in great shape. Once i took the drivers out...I notice one driver do not even move. I tried to push the cone gently in. WTF??? Is frozen rock solid. It does not move at all. The other drivers move in and out. Now... I am ******* screwed ..... I can not do shit without one damage driver. I contacted the guy / seller from ebay... he is Not even answering me. Now ....I am stuck.
