I bought this speaker to play with MB450H head as it is supposed to be done to go with.
I played it at home in my apartment, and repeated in concert with all kinds of volumes.
This is a 1x15 was especially severe and round to render frequency. Like its brother the 4x10 was something too round, too sweet and downright wet when you play, feel like the bass full of tallow and we will stick hands.
Dynamic level it does the job.
I used it for 2 years.
I've never tried other 1x15, so I find it hard to give me a concrete opinion on the matter.
I do not like much with this cabinet, I should never have to buy it.
With experience I will buy something else, and I especially try before!
