I bought this cabinet to go with MB450H head, because it's the same series that is supposed to be designed to go with.
I'm used to play in my apartment, in rehearsal, in concert, to all sorts of possible volumes.
The frequency curve is far from neutral, even with the tweeter is very round, soft and very cozy, almost wet, it gave me the impression that HP was wet (as if I had my hands full tallow and it stuck to the bottom, yuck).
Otherwise dynamic level is the only point on which he did the job.
I used it for 2 years.
I have not tried other model before buying.
I did not really like much with the baffle in the heavier it is.
For value for money, in a kilo Ferailleur, it must do so, basically, it's not a bomb and it does not really is very expensive, so it was worth the money.
With experience, I would take anything else, I played the head of a 4x12 guitar of the same brand, the result is clear that 4x10 crashed! Definitely not something else!
