I have a Behringer BX3000T amp - 300W at 4 ohms. I may be going to look at a speaker cabinet on the weekend - so far I'm not sure if its a suitable match for my amp. The Behringer has a jack for a speakon plug and then either side of that it has the smaller jacks for the speaker leads that look the same as guitar leads. The manual says that if you're using a single cabinet to use the speakon option, and if you're using two cabinets to use the other jacks with the smaller leads. The cabinet I may be considering is only set up for the smaller type of lead. I am wondering if anyone knows what would happen if you plugged into the cabinet using the smaller type lead into one of the jacks at the back of the amp. P.S. I don't plan on getting a second cabinet at all ever.
