I have a Peavey 410TVX now, and I'm hoping to replace it with a Dr. Bass Rx212, but I'm trying to make sure the 212 alone will be loud enough. I know there are too many factors to count, but I'm just going for an estimate, I guess. I'm using a Peavey Max 700, so here are the stats with each: Peavey 410TVX: 4 ohms, so it's getting 475 watts. 97db 1W1M (so I'm told). Four 10" speakers. Dr. Bass Rx212: 8 ohms, so it'd be getting 275 watts. 102db 1W1M. Two 12" speakers. I'm told sensitivity makes LOTS of difference, and I'm under the impression that, when it comes down to it, the 200 watt difference isn't really going to make a huge impact in volume, but I don't know how much difference the speakers themselves (410 vs 212) will make. Any opinions on whether the 212 will be comparable, or superior, in volume?
