I recently purchased a Sharp 777. Works, but one speaker is deformed (still plays okay) and another has tear at surround. I want to repair and recone the original speakers or purchase replacements. Does anyone know of a recone kit that fits the outer full-range speakers and look like originals? In the meanwhile I would like to upgrade the speakers until they can be repaired to avoid further damage. What are the best sounding speakers to put in a Sharp 777?
