Mesa Boogie Walkabout Mega-thread Part 10
- Thread starter Chef
- Start date
Good grief, I bet that 410/212 gets loud.
Finding the NX2-112T would have me set for those stage volume only gigs, dropping it on my NX2-212T.
Doubt I would hear a difference using the easy-to-find NEOX-112T. Gotta be picky. Darn.
I remember reading in this or another thread about guys adding that third 12. I wonder how much output increase that one driver makes.

McFarlin, IMO/IME it makes quite a bit of difference for a few reasons:
1.) Dropping down to 2.67 ohms gets a little more juice out of the amp. I believe it's somewhere around 400/430 watts based on a vague memory from a prior thread where someone actually measured the wattage at that load.
2.) You're increasing the cone area by 50%. That's a pretty significant difference when it comes to moving air. Couple that with the increased power and the perceived loudness compounds.
3.) That third driver is pretty high up, close to your ear much like an 810. To me the height of the third driver was a major factor in the perceived increase in overall volume.
For the vast majority of places I play, I never needed the third driver even though it sounded glorious. I already have too much stuff to carry, so keeping a cabinet home was an easy decision. An outdoor show would greatly benefit from that extra driver though, with or without PA support.

Worked great for me.
212 + 410 cabs. Both 4 ohm.
Oddly enough when I paired the Berg AE410 with another 410 (Epifani UL410) it was horrible!! They totally battled each others frequencies.

Hey guys, been meaning to ask this for a while now... I put the meter on the speaker in my Scout combo cab, and came up with 6ohms. I know it won't read perfectly 4 or 8, but given the reading, which is it?
That'd be an 8 ohm speaker. DC resistance is typically about 75% of rated impedance. A 4 ohm speaker would read around 3 ohms.

Thanks! That's what I had in mind but wanted to make sure.
Way up on the priorities list for this year is an extension cab, so the banter here on the Walkabout MT regarding what works well and what doesn't is especially helpful.
I gather my volume needs are considerably less than most of you guys... no stadiums or arenas for me, mostly these days I'm playing private parties, receptions, and bars. 80% of the time just the Walkabout/Scout combo is plenty, but for the occasional stupid-loud outdoor gig I need a little more onstage oomph to cut through.
Well... it's looking like there's going to be a couple more of those this Summer and like most of you, I find having headroom to be very comforting.

So I finally got a chance to toy with this a bit more and i am almost 100% certain that it is the crossover. Here is what I have done:
Tried a different driver - buzz still there
Disconnected tweeter - still there
tightened everything down - still there
changed tubes - still there
bypass crossover - completely gone
Hook it up again just to double check - buzz returns
Going to call Mesa on Tuesday and see what I need to do to get a crossover. Thanks for the troubleshooting help guys.
PK;
See if you can bypass the switch only. I can almost guarantee that, that is the problem. You can get the switch separately. All the best.

Hello all,
Just scored a WA 12" combo that is on its way to me. Have a question for folks with the extension cab. Forgive me if this is a silly question. Do you place them side by side or stack them? Does it make any difference with the passive radiator?

I've used them both ways.
Stacking vertically does not effect the passive radiators ability to do it's thing;
it's basically "a fancy port" allowing a small box to be tuned deeper than other methods might allow.
No worries.

Just me, but I like the sound of them side-by-side when I'm inside the 5-8 foot zone around them... I doubt it makes a difference elsewhere in the particular room.
Some guys allow it's easier to hear them stacked, by virtue of being closer to the ear.
YIKES! Don't push the passive radiator button again! Spirited debate ensues.

indeed!
When I did use the WA combo with an extension cab (at different times I had a Scout 12, and a Scout 15) I always stacked them. I found the best way to set them up was to tilt up the combo cab (top cab) with wooden wedges cut for the purpose. I was able to get a 15-20 degree tilt with the wedges. This arrangement gave me the push of both cabs and really got the sound of the top cab to my ears. Worked great.
enjoy your new Walkabout. Great amp.

I preferred them side by side as well. They gave off more low end from the added floor coupling of two cabs vs stacked.
this guy here got the best of both worlds x 2. Stacked and side by side.

My experience:
Stacked - better/clearer on-stage monitoring (ear proximity?)
S.B.S. - better low end projection (ports coupling with floor?)

What pfschim said... my Walkabout/Scout is one of those rare things in music-life that just doesn't disappoint.
Question for those of you that have replaced your cooling fan -
I put the Silenx fan in and, when I first powered it up, the fan didn't want to turn. I started it by hand and then it ran fine. I measured voltage at the wire splices and got a bit more than 9 volts with the fan spliced in and 12 when the fan was removed. Is this normal? Does the load of the fan draw down 3 volts?
It now runs fine and is indeed silent but I have to wet my finger and hold it over the vent on the amp face to feel the air moving. I haven't had any thermal issues and don't feel much if any heat after a two hour practice but this doesn't seem quite right to me.

That doesn't sound right to me. Was the fan running when you measured or was it stopped?
To drop the voltage that much it seems like the fan is drawing way too much current. That could lead to damage of the power supply.
