[SOLVED] s-dj80x tweeter died

My name is Kenny and I write music and produce and have been using a Spirit Absolute 2 for nearly 20 years with no issues. I bought your s-dj80x last week and lo and behold within a week of normal usage the tweeter on one of them stopped responding. It then came back on miraculously and then died again in a matter of minutes. Needless to say I am not happy at all and am very disappointed in Pioneer's products especially as it died on the weekend and I can't do anything about it until Monday.
