Hey guys. I'm looking at getting a single 2 x 10 Headliner cab to start off and add a 1 x 15 VB cab later. My head is a Peavey Tour 700 @ 4 ohms and the Headliner 210 is a 8 ohm cab with 400 watt handling. Running the 700 @ 4 ohms through a single 400 at 8 ohms does this work? I'm not concerned with rumble (until I can afford a good 15") just want to make sure I'm not going to ruin my equipment running it this way. I know theres all kinds of threads on over/under powering and Ohms, and I've read them all. I just want to be 100% that this is not going to ruin my gear.
