Mesa Boogie Walkabout Mega-thread Part 10

@Big-Uli

Here's the photo evidence. Sorry for the crappy iPhone shot. I'm just too spun up to break out the 35mm! Holy Mackerel! I loved the single CN112. I am so psyched about the Walkabout and CN212!! :hyper:

Lmao! That's a crazy set up. Makes me wonder what would happen if I stacked my 12 scout combo on top of my CN 212 when I receive it.. :D

ha, I have this capability now, but I have never really thought to do it. No need really with the WA driving the CN212.

Someone refresh my memory on ohms and multi cab loading/power distribution:

if you run the WA with a 4ohm CN212 + 4ohm WA 12 cab, you will be running the WA at 2ohms (which I have done many times in the past) and getting approx 485-500w from the amp.

I think there could be an issue with the WA 12, as I'm guessing it will effectively handle about 160w (Mesa rates them at 300w) before reaching it's useful limits. The CN212 OTOH is pretty honestly rated at 700w and 104db. So, I think there might be a power handling mismatch between the two cabs with this set-up.

Now another CN112 on top of the CN212 - whole 'nother thang. :cool:

We're all a little crazy... but in a very good, though often expensive way. I'm becoming a headroom junkie hanging around here. :D

Fortunately, two Scouts have me covered, since the only drummer I gig with is pretty sensible. Sometimes I wish he would get a little more heavy-handed.
 
That would make for a 2.67-ohm load, which the WalkAbout should be able to handle just fine. :bassist: :bassist: :bassist: :D

yes, indeed, I have done it many a time myself. I know from experience that the WA handles operating at 2ohms with no electrical or heating problems, but I do seem to recall feeling that it got kind of squishy when pushed at that load. That's one of the reasons I moved away from using 2 4ohm WA/Scout cabs in the first place .. and replaced them with the much more robust and efficient CN212.

So, the Berg CN112 is a 8ohm cab ? .. makes sense given that the CN212 is 4ohms.

I know this topic has been covered on TB before, but bear with me and help me out with the per cab power question. If I run a 4ohm 2x12 + an 8ohm 1x12 using the WA power ratings at 2.67 (which I seem to remember is something like 425w) what will I be sending to each cab ? Given the different resistance, I already know that they won't each get 212.5 watts. And the overriding question is, would it really be worth it to do so.

Each driver in that scenario would receive 1/3 of the WalkAbout's output power, which is ideal.
