Hi Guys,
I have a K100 with a 2X12 cabinet. We played a gig in late August and after the gig I loaded the cab into the trailer and went home. I took the cab out of the trailer list last weekend and the speakers are dead/open. The cab was working on the last song we played and we shut it down normally. Has anyone else ever seen this before. I will recone the speakers soon but it is very interesting that 2 speakers would fail while sitting in a trailer. Any guesses??????

I've seen what Steve mentioned before, but I would think that it would be odd for two to happen at the same moment.
What sort of temperatures have they been exposed to?
When you inspect/recone them, you may find something common or you just may never know.

I've reconed plenty of speakers but I guess I didn't think about fatigue. These are original C12N's and I suppose one could have been bad and then the other one failed due to DFL. I use SimplySpeakers.com for my reconing supplies. They are very helpful and fast. The only kit I had to wait for was a JBL drop-in for a 2226. I may even have a C12N with the cloth dust cover sitting in the closet. I was going to recone a working C12N just to match the dust covers. I haven't gotten to it yet. What a surprise.

Well, both speakers are done and installed. They are VERY stiff. (OK, now I believe in a break-in period) These are definitely different than JBL E series speakers. I want to use these K100's on small stages using a PA to increase the coverage while keeping stage volume lower. In that vein, I wired the 16 ohm speakers in series for a total of 32 ohms. The 60 watt @ 8ohms amp will max out at 15 watts @ 32ohms. It is very interesting how the amp breaks up when the amp starts to clip. This gives more control as the amp can be run from 10 o'clock to 12 o'clock and still not drive you out of the room. I may put a switch in one of the portholes to switch from 8 to 32 ohms easily.
