Hi guys,
I have been using my Beomaster 3000 with a pair of Beovox cx100 for a while now. Today I bought a Beovox cona to upgrade the bass. I plugged it in and now it doesn't work anymore. I plugged the beomaster into the input side of the cona, and then the cx100 on the output side of the cona. The problem is:
I hope that you guys can help, so that I can enjoy my new cona subwoofer
First thing to check is make sure you don't have any strands of wire shorting out where they attach to the Cona, some of your symptoms sound like this could be happening. Doesn't take much, a single stray strand of wire between positive and negative can do it. Other than that, it could be a shorted driver (it's a dual voice coil woofer) or a bad crossover in the Cona. Did you hear the Cona work before you bought it?

I'm afraid I'm recovering from the BeoVirus.
Thanks for your quick reply Jeff!
I did hear the cona play before I bought it, so that can't be the problem.
I don't have that much knowledge on this subject, so I think I don't understand your solution yet. Do I need to change the wires in the DIN plug (+ to -) or do you mean something else?
From what I remember of the Cona it didn't have standard B&O DIN speaker inputs but instead had regular speaker terminals that accepted either bare wires or banana plugs. On the bottom of the speaker. When you use bare wire in that kind of connector it's not hard to get a stray strand of wire that sticks out and can contact the other terminal, creating a small short.
Check that wiring (of course I could be wrong about how the Cona is wired, been a month of Sundays since I've laid eyes on one so I'm going from memory). Also check where speaker wire goes into the DIN speaker connectors B&O uses you can get stray wires there if you're using a wire into plug and not a premade speaker wire that's sealed.
Other than that if the Cona was working that kind of goes against it being the Cona, even then most times when a cap fails it goes open not shorted which shouldn't be a problem.
You are running two wires to the cona and then from the Cona a wire to each CX100 right? Are you sure you have the wires connected to the right places? L and R in to the Cona's inputs, the Cona's outputs to the CX100s?
I'd bet you have a wiring issue somewhere.
