I'm going to have to ship it back to GK for an issue with the handle. (one stripped screw) That's right, ONE handle ...on the top. GK really takes care of their customers, so no worries there.
I really wish I still had my AE410 to compare it to, I think it's "in the ballpark" but it's hard to say just using one's memory. At one third the price, I wouldn't expect it to be anywhere near the quality of the Bergie. Compared to my beloved MB212, it sounds MUCH bigger and all the frequencies are well represented. It doesn't have that lump in the lows which, I believe partially comes from the MB head they use in the combos. (The MB2-500 head I owned for a week was uncontrollably boomy with ANY cab) Of course, the tweeter sucks...you want it [ON] or [OFF]?
As far as size, this is as small as a 410 cab can be. With no ports, they were able to make this a 23" by 23" square, 16" deep though.
My preference is not for super-smooth hi-fi sounding stuff OR baggy-feeling 'peg-ishness. It's somewhere in the middle and GK seems to be "my voice".
I'll try to get a pic before sending it back.
