That's more or less like a small area horn mouth (with an abrupt flare).

In general, a smaller mouth give you lower cutoff, also a lower SPL.

By the proportion of the diagram, it'd be a midbass horn, not a sub. Also, tapped horns have severe resonant peaks in their higher range, which should be filtered-out, thus narrow usable bandwidth.

In the POV of the whole system, a narrow range midbass unit might not be a good idea. A plain straight midbass front horn with simliar cutoff, wider range, better directivity, smoother response... etc. won't be terribly larger than this.

You have several big round wooden tractric horns, don't you?

The design has similiaries with the decware wicked one , but the idea is to sum
the advantages of a tapped horn, with the advantages of a slot loaded sub, and use it up to max. 150hz.
If the horn is too small for the intended frequency range, i might modify it. Maibe someone can help with
better suited dimensions.

Have a look at the Cubo Designs Hosted on Freespeakerplans.
Plans
The cubo has been built sucessfully as a dual speaker, simlar to what you propose.
Have a look at this quick sketch based on the Cubo sub to show you where your proposed design differs in the horn path proportions.
The panel between the speakers could probably be shortened, or removed.

interesting. i would like to understand what distance one woofer would need to have to the other , to get a Heil-style loading effect. I guess the closer each woofer to the other, the better ?
