I just picked up a pair of Heresy 2. Cosmetically, the speakers are in great shape. However, they are not perfect. The "plastic" fabric backer on the grill has bowed over the years. As the result, the grills are lifting on the corners. Though the speakers are in great shape, the lifting corners sort of let down the overall physical appearance. Has anyone seen this? What is the best way to get them sorted? Thanks in advance.
