They're Promedia GMX A-2.1's. 13 months old, so warranty just expired a few weeks ago... Anyway, this morning I went to plug them in, and... nothing. The little LED of the volume/bass control pod no longer turns on, either. Any ideas on what happened? There was no smoke/smell/anything. How does one tell if the fuse is blown? And where can one purchase a 2.5 A, 125 V fuse... Dammit, they were such gorgeous sounding speakers too.
