Antone,
I've been pondering the problem of stronger low mid too but then I back up and ask myself...are you certain that more midbass is what you need? While toms and guitars can benefit from midbass, vocals can get boomy real quick if they are abundant in the 250Hz region.
I've heard a few PA's out there that needed some slight cuts to the low mid because they had some bad resonant frequency or something. Maybe it was due to using cheap speakers.
Oh well, just food for thought. Carry on. Gordon

My experience in hearing the improvement of midbass through a good straight horn is quite like the improvement in hearing sub bass from a well designed folded horn (aka LAB sub). In either case, more "loudness" wouldn't be the point so much as reduced distortion, better intelligibility and nicer sound.
My experience has been that the problems of boominess or loudness go away when using a proper midbass horn to cover that range.
Larger systems with multiple full-range cabinets present a possibility or two to work around this.
Installs sometimes use dedicated midbass horns as a direct way to address this need.
Otherwise, integrating an effective sized midbass horn into a full range cabinet would either impose limitations on the horn (and therefore require multiple cabinets coupled) or else would produce a rather large speaker.
In this case the poster is trying to bridge the gap between tops he already has, to subs similar to the LAB subs in perforance.
