Just got the 2x10, ran it as an extension cab for my Eden Metro..cranked it up pretty loud, I believe that with the 8 ohm cab, the head is running a 4 ohms, with the internal speakers engaged. With both cabs (internal and Bugera) running, sounds pretty damn good..when turning off the internal speakers on the Metro, sounds...pretty good, loses some "thump", and some low mid. Also ran it as an extension cab for a 90's version SWR Working Man's 10, sounds really good..when run together with the Eden, definitely works great...for $250, I'm keeping it, and I will most likely add the 1x15 later, as the Eden can run all three. Build quality is excellent, a little heavy, but not ungainly..if you are looking for a pretty good cab that you want to pair with a lightweight head ( I have a TC BG250 combo, 2x10, wish it had an extension cab output, may add one myself) I would recommend this cab..say what you want about the company, and how they advertise, but this is a really good deal..of course, I reserve the right to change my mind after spending a couple weeks with it...
