Midbass tapped horns?

[Rik_bS]

smaller sized bandpass-horns are a better option in my opinion for low-mid range horns.

yep, BPH for low mid "kick" - when playing with sims, keep an eye on impulse response

Is there any 10" BPH?
May be this will fit?
It's a modification of Cowan 10TH which I very like.
Double version should work up to 300hz.
Or ... may be not.
