Man, you're full of awesome info. Thanks a lotUncle E wrote: The Jet City Eminence is actually much darker than a Greenback. That's not necessarily a bad thing, you just need to dial in extra presence to get the same sound, but I don't think the speaker will be hurt by being in a brighter cab if someone is after more of a Greenback sound.
btw, the Jet City Eminence used together with a Greenback is glorious.
I'm leaving it totally stock, the more I play with it the more I like its inherent sound and responsiveness. I'm guessing they picked the speaker for the 1x12 intentionally to offset the way that smaller, single-speaker cabs can tend to sound either boxy or ice-pick shrill (or both, ugh, I've had some bad experiences with 1x12 combos). If it is indeed basically a slightly adjusted Soldano cab design with a speaker that's matched up perfectly... I just don't see a downside. Its construction quality is great, screws in all the right places, even the purely cosmetic stuff is well put together. More expensive cabs that are still in the affordable range have impressed me far less. I am concerned that if I compared this to a THD 1x12, matched to the head I'm using, would be at best a side-grade in terms of sound quality.The wood is all 3/4", by the way, which is pretty much exactly what it ought to be. I've cranked my amp and while it only pushes around 17W with my tube configuration when fully engaged, it is still extraordinarily loud... and the cab doesn't lose any of its nice qualities. It keeps up very well.
I can only speculate, but I would feel very comfortable based on this experience investing in the 2x12 version if I wanted a higher wattage setup. This is cab engineering and production done very well. The price is ancillary to the quality, frankly. I keep coming back to this, but I'm just used to paying WAY more for gear than this, and I'm pretty blown away by the quality of this.
I know I'm working for Wampler now, but Wampler doesn't make cabs, so I will be contributing a review to FrugalGuitarist (I want to keep doing that so long as there aren't conflicts of interest). I get the itch to review still, I just can't write about pedals now even though I still spend too much money on various things
If you have any other cool info you'd like to share, Uncle E, I am all ears and will give you a nod on my blog as having been really helpful in better understanding the product. Fawning only takes up a few paragraphs, you've already given me a lot to think about in writing a cool article that explains what is so nice about the thing. Thanks, man.If anyone has tried the compact version, I'd love to hear their input too.
Thanks for confirming it is a 12" and rough esitmate of the euro damage...i may just make it the one my friend 
I have not got a social life so this is like a 
everything about it, just have to wait and see what it sounds like for myself now and oh yes speaker subject to change/swapping out like a hot swap disk drive 
I will find something)
