Since the 12/6 is 8 ohms and has the 3012LF, I'm guessing that it wouldn't be a great one-cab solution for a Mesa Walkabout head. If that is the case, what is the minimum wattage acceptable for this cab?

The fan might be different on the BX series versus the B series. The fan noise certainly wouldn't be audible at loud gig volume. That said, if you were playing a coffee shop gig behind an acoustic guitar player it would be audible. It would also make this head a bad choice if you were in a studio setting where you had to have the amp in the same room as the mic'd cab. For loud gigging it would not be a problem. Unlike your amp, mine is not yet in a rack case, so that could be a contributing factor as you pointed out.
I can afford to keep the Puma. Frankly I could afford to keep both, but I imagine one of them (suspicions point to the Carvin) would end up sitting around unused and that's just not my style
I should point out that my review is not based on a live session with a band and should be taken as "initial at best." My feelings might change once I hear the amp in a live context.
I had the same thought as well. I tcould be that Carvin is simply building these to handle the most extreme gigging situations. I don't recall, but I seem to remember that this amp is stable down to 2 ohms. The massive cooling might be for those situations where someone is running a 2 ohm load on an outdoor stage in the middle of summer in Phoenix Arizona. A variable speed fan might be a better choice for Carvin in the long run. It really was shocking when the fan got up to speed when I initially turned the amp on. Again, on a loud rock gig it's a non-issue. In a non-isolated studio environment or on a quiet coffee shop gig it's loud enough that I would consider it a problem.Nice review. Lot's of comments on the loud fan on these. Strange, since you would think the class D amp would run reasonably cool and not need that much oomph with the cooling.
Agreed. The more I play it, the more I think the center of the treble control is set sufficiently high, but the Q must be extremely wide with a very gentle slope back towards the upper midrange. There's a lot of gank, honk, quack, nasal, etc. tone on that knob which I think is a real downside. All of that type of tonality should be isolated to the upper mid control. By comparison, the upper mid control on this amp feels very narrow and behaves more like a notch filter. I do like it for that, but that treble control needs to be revised.Your comments about the top end remind me of my review and experience a couple/few years ago when I had a B1500 for the trial period... glorious power, nice EQ, good, strong punchy tone, but something not quite right to me ear way up top.. a little bit harsh in the lower/upper treble to my ears. Amps like Markbass and TecAmp kind of spoil you up there! Otherwise, it was a great amp, and a fantastic amp for the money.
Keep in mind that those EQ settings are nothing like I've ever used before. On my LMTube it's flat with the VLE dialed in to about 9 o'clock. When I used to be a GK guy, it was flat on the bass and treble, a slight low mid bump and a slight hi mid cut. My Aguilar DB750 was flat except for a slight midrange cut. I'm not one to use crazy amounts of EQ to get my tone. I'm hoping the Puma1000 is closer to my liking with all the knobs at noon. It allows for so much more control when you're in troublesome rooms that have to be EQ'd hard to sound good. If your starting point is all over the map you don't really have anywhere to go in certain cases.Given your EQ settings, I have a feeling you will LOVE the Puma voicing, which is deep, smooth and crystal clear all the way up set relatively flat. The most EQ that I use on mine (depending on the cab) is either a slight cut in the upper mids to eliminate the 'gank' that some cabs have in that 1K region, or bump up the low mids on cabs that are more wide and big versus punchy and tight (rarely moving those controls more than through the 11 o'clock to 1 o'clock range).
Consider me BEYOND excited for mine to show up. Big thanks to ::::BASSIST:::: for pointing out the one for sale in the classifieds. I wouldn't have seen it otherwise.With the 15/6's I've tried it with, just a very minor cut in the upper mids made me very happy! I think the Puma1000 is voiced just a touch differently than the Puma (I think a bit more low mid response if I remember correctly), but that would be a good think IMO.
I'm running my 15/6 with a ShuttleMax 6-----375watts at 8 ohms. Loud as hell, no compression in small to medium sized venues.
Agreed. The fan would likely be audible and an acoustic / coffee shop type gig. The fan is definitely on the loud side.The fan might be different on the BX series versus the B series. The fan noise certainly wouldn't be audible at loud gig volume. That said, if you were playing a coffee shop gig behind an acoustic guitar player it would be audible.

@Ken - is that picture a 12/6 or a 15/6? I just sent Don a email, I am going to get in line, so to speak, but still up in the air on spec. I will go with a 15/6 for sure, but that's all I know right now!

Yes, I am pretty set on a fEarful 15/6 with the 3015LF / 18 Sound. Based on your earlier recommendation, I think I will go with the variable L pad for the mid. I am thinking the 800hz crossover will work. I am a little concerned a with this, since I really don't like the mid "gank" or "clack' that seems to be a factor in some cabs. I want to make sure I can eq it out or adjust the level of the 18 Sound. Thanks for your help!
