Let's talk about Behringer paper speakers

My wife's been running her G-K Backline 600 head into the
15" speaker of a Behringer BX-1800 combo amp. I just drilled
a small hole in the back and ran a speaker cable into it.
TBH, it sounds really good, but that's at bedroom volume.
I'm skeered to turn it up, 'cause I don't want to blow the
speaker. Should i be worried about this? Thinking about getting
her a 2x10 cab and use both for gigs. If her Backline ever
***** the bed, she'll always have the weak Behringer combo
right there as a backup. Is 2x10 and 1x15 a good idea
anyway?

All the blah blah about Behringer aside? I'm running a 2x10 paper cone with an Ampeg B2R for my open mic rig.with vol and master never above 12:00,and the EQ flat. The horn popped, I'm not missing it, but the speakers are fine, and it gets loud. I have players looking into the grille and asking what I'm running in there. I'm using it more and more for regular gigs and it's been really good. It won't last forever,I know that, but at $170.?It's already paid for itself, and another. I like it. But proceed with caution evidentally some folks have had very bad experiences with them.

Thats what needs to happen if you want to keep the combo head intact
In my ( misguided) youth, I ran a Fender Showman head into the speaker of my little radio ( maybe a 5" speaker) for about 10 minutes. It fried the speaker which was to be expected. It also destroyed the circuitry of the radio as I only wired the Showeman directly to the speaker leads, allowing the signal to go through the radios circuit

Why would you be scared to turn it up and try it out? It isn't like it should just go 'pop' and 'poof' all at once.

Take it slow and bring up the volume a little at a time - If the speaker is stressed, you will be able to tell by the sound it makes.

600 watts into a 200 watt speaker isn't too bad, and thats if the 15" is 4-ohms. It most likely is 8-ohms and so you are only pushing about 300 watts into a 200 watt speaker with that GK head. No worries there.

That's the only thing that worries me about your description (and maybe you did disconnect the speaker leads to the combo). All the rest about Behringer, paper cones, etc. can easily be bypassed by just being careful - don't increase power abruptly. If the speaker complains, consider plan B. BTW - the vast majority of speakers have paper cones of one sort or another (including the majority of high end and high power drivers). They are very durable.

I disconnected the power to the combo, thought that would be OK, no?:confused:

That's OK, if you mean that you disconnect the speaker from the combo's amp, but if you run a second cab with the GK, you'll need to make sure that the speaker in the combo and the additional cab you run with it are both 8 ohms so that you will not go below the 4 ohm minimum impedance.
