How much does rear horn loading add to full range driver?

Found a tower speaker using a single 3" full range Tang Band titanium driver. The rear wave is horn loaded via the 43" tall tower. The speaker had some pretty good reviews.

I listen at lower volumes in a smaller room.and actually have some Norh 3 drum speakers using a 3" Tang Band driver. The enclosure is roughly LS/35A size and ported. For vocals they are loud enough. Norh claims they play down to 75hz. 

How much volume is gained by horn loading the rear wave? Would a horn enclosure 43 x 9 x 6" inches be likely to play lower than a ported shoebox size speaker? These wouldn't be my main speakers, just an interesting addition.

Thanks,

I'm enjoying my Closer Acoustics Ogy immensely. They're the smallest back-loaded horn fullrange driver speakers. Bass is surprisingly good. Midrange is blissful. Vocals are... wow! Highs are a bit on the brighter side. The drivers are EMS LB5. 

It's common ASR wisdom that "fullrange drivers are hot flaming garbage and you should be deeply embarassed to evoke them in any conversation". 

Do what you will with that knowledge.
