The cover sits flush against the head, and doesn't direct airflow anywhere, that I can tell.
It appears to me that air is supposed to exit out the front slots...

I always preferred them stacked vertically (tall), rather than horizontally (side-by-side).

I almost always trim at 50-60hz to keep the low end under control/tight.

If you look at how the amp is mounted into the Scout combo it covers the gaps on the sides of the amp. On the older units the sides and top are the only vents. Even with mine and the extra venting on top of the head, when mounted in the scout most of the heat is directed out the right side of the amp when viewing the amp with the cover off.

The stock fan seems to move much more air than the top vents alone could allow. Most of the heat is then forced out the sides as seen in my brutal paintbrush pic here:

Here's my Scout with the cover off to illustrate the air gaps on the sides:

If you look on the bottom of the Scout where the amp sits you'll see square holes on either side. That's where the most of the heated air is expelled when the cover is on:

Since I added the straps I think the most notable improvement in the air flow is actually allowing the heated air to escape out the right side at the top as opposed to being directed down the sides to where the fan can suck it back in. That's where I feel the most heat and air flow on mine with the cover off.

I haven't heard a PH115 but have owned PH112, Scout 12 and 15. I much prefer the Scout 12 over the PH 12. The Scout is tuned quite a bit lower, and is almost 10 lbs lighter. The PH112 has more mid emphasis. The Scout 15 kills, is tuned very low, and you may have to cut back some bass on your eq, but it's a drag to carry with it's inadequate, single side handle. If you want a 1 cab solution, the Scout 15 is far louder and can use all the Walkabout's 300 watts. The 12 cannot, and getting a 12 in 4 Ohm, (which is unfortunately the standard) makes no sense. I have owned the 12 in 4 and 8 ohms simultaneously and compared them: they both start to compress at the same volume from the Walkabout, so there's zero advantage to the 4 Ohm version, contrary to what many at mesa and elsewhere will say.

I've played the PH 1X15& I likened it to my old EV 1x15-TL606 cab. Lots of low mids & punchy, but not a real low freq cab.
I liked it, as I do the TL606, but imo, the scout 80's just nail that vintage 'bloom' that I remember from my old 2x15 JBL's.
So, better, imo, yep. The WA Scout is. But that's just how MY ears hear it.
Yours may hear things differently.

I've been having the same question as Wimpy: whether to add a Scout 15 or a PH 15 as an extension to my WAScout 12. This thread's got me convinced that I'd prefer the Scout 15 to the PH.

Now I'm wondering if maybe the thing for big loud lows on gigs is to skip multi-cabs and build a fEarful 15/6?

IME you won't really get the fEarful to bloom with 165 watts. It's fairly sensitive but maybe not enough. Sounded great but no louder than the Scout 15 IME. That's based on my LDS 15-6 nEarful. If you can bear the wait, I'd highly recommend the Audiokinesis Thunderchild 12 (available in 4 Ohms). I had it and loved it so much I ordered the (soon to be released) 4 Ohm 15 version. That will be IT for my Walkabout.
I also tried the Avatar TB153 in 4 Ohms which was outstanding, but at 65 lbs, a little more box than I want to haul up/down stairs. I have tried a gaggle of cabs with this head and for me the 212 and 4 Ohm 15 config sounded best and loudest.

I'll be curious to see what you think about the TC115.
I doubt any single driver will be loud enough for me, with this head.

In the back of my mind, I've been contemplating two Fearful 12/6/1, but man, since the increase in driver cost, that's quite an investment.
12/6/1+12Sub would be substantively cheaper, but leaves me wondering if that would have enough mids and highs for me.

I am still seriously thinking of ordering an extension cab for my Scout 12 but hate the thought of running at 2 ohms all the time. I was also considering a pair of Scout 12 extention cabs and a WB head case but now the Scout 15 is peaking my interest!


My favorite setup with the WB so far has been a pair of PH115 cabs but I no longer have them as they were quite a pain to move.

Too many options!

I'd be curious to know how the sensitivity of 2 3012LFs would compare to 2 good "regular" 12s (like the Scouts). It seems that 150 watts into each 3012 LF won't be any louder than into another good pair o' 12s. My guesstimate is that the TC112 with 300 watts was pretty much as loud as the WA into a 4 Ohm Scout 15 cab (at a much lower weight). Since the TB153 was loud enough for me, I suspect the TC15 will also be. However, since I have 3 basses FS, when they move, I may still be tempted to try yet another cab configuration with the WA. I was so impressed with the GK neo2-112 that a pair or trio of those might be the next experiment. I don't think a pair of those will fart with the WA maxed/ neutral eq. They are very light and I dug the tone. Meanwhile, later this week I'll be doing the fan mod and, once the top is off, some tube rolling.

I'm currently using a second Scout 12 under my WAScout (both cabs are 8ohm). It sounds great to me, but sometimes I need more volume. I once posted the thought that maybe I needed two WA heads; lomo I think you replied that wouldn't help my volume.

Now I'm wondering if a 4ohm 15" Scout cab would be a better extension to my Scout 12 8ohm?

This oldies band I'm in has 3 guitars (that's one too many), and the only thing that works in the mix is to be very bassy. Midrange disappears into the "wall of noise" being created by those three gtrs. I'm looking for a pretty big boom.

Well, unlike the 12, the 15 WILL be significantly louder in 4 Ohm as compared to 8. If you just need a little more volume and low end, that should do it. However, if you want a bit of headroom, the best idea may be to give in and get a 410.....that's another option on my list. I am considering an SWR Golight 410 or pair of "regular" 15s.
