I just got my new avatar 410 neo cab (4 ohm), wow it sounds great! But, I have a very loud drummer & loud guitars( classic rock, etc.) I need more volume. I have an SWR SM400s 550 watts bridged into 4 ohms. I want to add either another avatar410neo or the 212 . Would I get more volume running in stereo mode @ 250 watts ea @ 4 ohms? Replacing the 410 W/ an 8 ohm cab is not an option!
