Older Axiom designs - like the AX3 I traded in during the last anniversary meeting many of us attended in 2011 - had large woofers in the cabinets. Unpowered, but they had them within internally separate enclosures.

I can tell you my M80's are much better. The design you propose sounds like many on the market, including the Reference 3a Suprema, which was very expensive and probably the best loudspeaker at any price that I have heard.
