Hello! I have a problem with my two-way speakers. I have four of these speakers, and none of them work. It seems like i have overloaded them, with too much power, and that the protection circuit has turned on. The reason why i have come to this conclusion is that i have cross-testet amplifiers, cables etc.. All the drivers seem completely fine as well. I find it so odd, that all the speakers capitulated at the same time. The tweeter works on all of them but the two drivers will not work.
What amplifier are you powering them with?
Remove the crossover and inspect it for damage(burnt/blown parts), post up some pictures if you can.

I have been powering them with a TPA PRO Rat 72 amplifier: http://www.tpa-pro.com/Products/Show_127.html
I am new to the game and i therefore suspect that maybe the amplifier provides to much power, i drive all four of them on the same amplifier in my rack.
The amplifier works great with my other passive speakers, so the amplifier is okey.
My english is quiet bad so what do you mean with the crossover?
Here is some pictures inside of one of the speakers:
Behringers own website says that they have built in a protection circuit in the speaker, but stupid me cant understand which part that is. And is this a part that is changeable or can be turned back off, if it has turned itself on?
Another weird thing is that, everyone of them worked fine, the last time i used them. They have been stored inside, in normal room-temperatur.
The bulb on the circuit board is also perfectly fine on the speaker i tore apart.

do you have a multimeter?
the bulbs are ok if your horns are working.
if you don't have a meter you could use a 1.5 v battery to pulse the low frequency drivers to see if the voice coils are ok.

If the actual power output of that amp matches it's specs or is even close then it has more than enough power to melt these speakers. Behringer over rates most speaker products so those boxes are really 500w nominal 1000w peak. Do you push the amp to full output when in use?
If you have a multimeter test the woofers directly on the ohms scale, if they are open circuit they are blown. Alternatively you could just connect speaker wires directly to each driver from the amp, if there is no sound again they are blown.

The bulb on the circuit board is the "protection circuit" for the high frequency driver, there is no protection for the woofers.
The bulb can be changed if it burns out.
