I just bought a 15 inch Ashdown Blue Line speaker that was pulled out of a cosmetically damaged c115t combo. I also bought a MAG 300 combo head and four Blue Line 10" speakers. I copied the dimensions of a MAG 115 deep cab and a MAG 410 deep cab and had empty cabs built to those specs by steelsound. The 115 cab from steelsound just arrived. I hooked up the 15 Blue Line and . . . nothing. Dead silence. The head works fine, and so do the 10's. I hooked each 10 up in the cab, connected it to the head and each 10 works fine. Obviously, so does the head. So the 15 is definitely DOA. My question is: what to do? The eBay auction was "as is". The auction description said it was in excellent condition, but I think that would only apply to someone who plays very quietly! I have emailed the seller and am waiting to see what he is willing to do. Assuming he doesn't have any other Blue Line 15's to swap me, can I get the speaker repaired? If so, where? Does anyone know if Ashdown will replace or repair it? I did not get a manufacturer's warranty with the speaker. If repairing isn't a viable option, what 15 inch replacement speakers should I consider? The 1x15 cab dimensions are 19.5" H x 23.75" W x 16.5" D (approx. 4.4 cubic feet), with a vent slot across the bottom of the cab (just like the MAG 115). The cab is pretty sweet, so I don't want it to go wasted. Thaks in advance for your input.
