Hey Cliff...welcome...
I have the as-b1/b2's sitting in my basement they were my very first speakers...
. I also own some Axioms and had the Sierras 1's(but now I have the towers) and comparing them(Axioms) to the Monitors would be a very good comparison...imho.
I might be in the minority here but I don't find my 22's as "bright" as often claimed by others but rather forward(I don't consider bright as being a bad thing...
) in nautre. They lack the required resolution or dynamics in the midrange and the detail up top to be a revealing speaker. Comparing the sound of Ascend vs. Axiom...I'd say the Ascend have the upper hand in all those areas as they're the more telling speaker. Throughout my listening sessions they never once sounded congested or compressed..always sounding crystal clear...keeping their composure no matter what voulmes I was listening at.
Enjoy your new cbm170's(duh...not Sierras) and I hope this gives you some idea on what you should come to expect with your Ascends..
Regards, Bill..
