Default Space Saver Horn

Taking inspiration from Bill Fitzmaurice and the V-Plate, I wondered how far can you take this concept in the battle against Hoffman Iron law. Good horn subwoofers require a big mouth and you can't cheat by just rapid flaring in the last few inches of cab. I'd expect this design to have poor low frequency loading as a standalone, but pair two cabs with piano hinge and a top plate and you have yourself a big horn subwoofer that packs down in the van.

Anyone else experimented with designs that use the outside of the cab as the final flare of the horn?

Pretty far if setting/sealing on flat ground.

I also have thought of this. Apparently most agree it works but no one seems interested enough to build some. I learned how to sim and got some pretty good results. Horn Extender/Wave-guide for TH

The idea has been tried...

J Bell designed a "bass stick" that was designed to be used in a "V" configuration and top-plated.

See here:

Dual MCM FLH

I built 4 of them, and used them side-by-side without v-plating. The floor and their fronts made two sides of an extended horn. Worked very well.
