I was able to listen to the M80ow initially, as it was the first speaker to arrive. It's not a ported speaker and I was able to set it next to the M50 and compare. The M50 had significantly more imaging and of course better bass, which was expected. I was expecting the M80ow to have better imaging. That is what lead me to swapping drivers. The M5ows sound similar to the M80ows.

Lots of speakers from many
manufactures...mostly Axiom
