Hey guys, last weekend I played a gig with my Aguilar TH500 and a DB112 cabinet. Worked perfectly. Today on rehearsal, plugged in my bass and ... no sound. Changed cables, power cords, speaker cables, tried another amp (which worked fine with my bass). There's only some high frequency noise coming out of the tweeter, nothing from the 12" speaker. At home, I tried another DB112 which worked fine (same cables, bass...). I opened up the cab to check for loose connections and everything looks normal. I took of the grill cloth to check the conus, and it looks totally normal. When moving it, it feels normal. I used the same setup last saturday without any problems and today it doesn't work anymore... I've been using this setup for years with a DB751 on many gigs, some of them really loud with a second DB112. This last gig was a low volume jazz concert, so I can't believe I've fried it... Any ideas? Edit: Opened it up to do some measurements. After reinstalling all the cables, it worked fine. Probably a ground issue with a bad/loose connection. BTW Marco at Aguilar contacted me and suggested to check all the internal connections, like dmusic148 said. He wrote that it's rare for that to happen but check this first if you experience a similar problem. Thanks for the answers guys.
