Bought two days ago in time (pure business elsewhere ...), I have not tested much.
That said, after a quick test with a guitar, a head that was not mine, I can tell you it blows ...
PRS (model Tremonty I think, not a true sum) ENGL savage 60 ... Fucking is the lower is ProRes, defined, no wheezing, the low and high medium, it takes a sharp ... In short, a terrible performance.

Equipped with Vintage 30, impedance 16 ohms.
The cabinet is extremely heavy, but next, it's light Engl ... but really.
The right speaker is a huge grid that exudes strength (like I go into the amp with my rangeos and I break my foot ...)

I think I fell in love. I can not wait to try it with my guitar (Jackson SLSMG 81/60) and my 5150 (for repair ...)

I will try to take a picture because we do not find any on the web ...
