I've done a search and read the FAQs, but haven't been able to find an answer to my question, or at least, not one I could follow. So here goes: all other things being equal, is the perceived volume/tone of a given output the same at 2ohms as at 4ohms as at 8ohms? I.E. In terms of perceived volume, is 300 watts at 2 ohms the same as 300 watts at 4 ohms or 300 watts at 8 ohms--to be a bit more concrete, let's say I was putting a Mesa 400+ into either a 4 ohms Eden 410xlt cab or else into an 8 ohms 410 xlt (or a 2 ohms 410 xlt if such a thing existed). a) Would the perceived volume be the same? b) Is tone affected? I ask because I've heard people claim that a particular ohm-age is somehow "better" than another, and I am currently debating getting a new big rig cab (412/810) for my 400+.
