Again Dan, I don't know why you call this the "Dunlavy type"?

Many manufacturers have utilized a M/T/M or a W/M/T/M/W vertical array. John Dunlavy did not create it. More commonly it is referred to as a D'Apolito array. That may be correct for driver placement but even then there is more to the overall design concept since I think Mr. D'Apolito specified the characteristics in the crossover as well for consistency with his design parameters.

To be a Dunlavy type a speaker would need to incorporate time/phase coherency (step-back cabinet panels for each driver and first-order crossovers) and be sealed box. I owned Duntech Princess speakers for 19 years and over that time I had personal conversations with Mr. Dunlavy and auditioned many of the Duntech and DAL models.
