I don't know of any free folded horn designs for 21's..... Scoops- yes, reflex- yes, bandpass- yes.

If possible I would like to examine the bandpass and scoops plans. Also would like to know your opinion comparative being 18 vs 21 inch for PA in open place.
I'm sorry for my bad english.
Thanks in advance.

21's are nice on sub base, but the cone's are too big and slow on anything above 80hz in my view.....
