going by Bill's figuring of depth = 18.7 and height = 28.5 with 3/4" material, what might be dims at question marks on this figure? - drawing is a bit off-square - doesn't appear to much taper on the first board

just maintain area expansion of vent.

How will this geometry perform for this driver as compared to a typical front loaded horn with compression chamber around driver?
It is really a compromise between a bass reflex and backload horn, both of which will not perform as well as a compression horn.
Of course the compression horn is 3 times the size if done correctly.

did Sieler achieve useful lowpass cleanup with the non-tapered section? how might his d130 box model on AJ?
thanks - will get that done - drawing in question was Sieler -- looks like very little if any real expansion on the first section - why did he pick that? (assuming drawing good)will 2220 have too much kick in your horn to work 2-way? (you know my bad balance tastes)
