Recently, while using my Energy EW-100 Subwoofer (connected to a VSX-822 A/V receiver), it all of a sudden cut out. The subwoofer itself is still intact (no holes or perforations in it) but it won't turn on, aka no power light on at all. I thought at first it was just over heated (as it was playing fairly loud for a little under 2 hours) so I left it overnight to cool down, however it still won't turn on 3 days later. I'm wondering if subs have some type of fuse or what not on the inside that can blow and would in turn stop the sub for turning on at all. If so, is this an easy/inexpensive fix? If not, what else could be the problem? And is it fixable. Thanks.
