now I'm really curious ho it's gonna turn out in the evening! Of course I'll let you know about the result. I will A/B it with the 4x12 Marshall.
Did you put it on the floor without bass boost or did you place it somewhere higher with bass boost?
Interesting what you say about a second Kabinet... so you would not recomend to get a second cabinet for a fuller sound?
So not really done it with a back to back comparison and only used the second Kab once, but my initail observations are
1) 4x12's are way more directional than you think. Off axis they don;t sound that good and levels drop massively
2) FRFR ( and this applies to Kab although not strictly) have way more spread, giving for me a disproportional amount of volume/power compared to a regular 1x12
3) Because of point 2, I foudn little difference spreadwise. Volume dropped ( presumably due to Ohmage) so I had to turn up. So diffcult to discern a massive difference...but then I'm not missing any volume anyway.
I had it on the floor I think with bass boost on.
