I think they are built by Axiom, to Bryston specs that are also based on Axiom's but improved with money.
Yes, it is well known that the Mini T and T are built by Axiom as the OEM.
I note that these look similar to the Axiom, but not identical.
My bro-in-law has a set of Axiom speakers, I can't remember if he bought the M60 or the M80 models, paired with a Rythmik FV15HP sub. It actually sounds very good, despite most of the dislike for Axiom that I see on AH.
What I do really like about his Axioms, is that the center channel is a beast! It is the same size as the towers, but a horizontal configuration.
