Default 18 inch Tapped horn

Parts express has this driver on sale.

B-52 SP-1804 18" Cast Frame Professional Subwoofer 4 Ohm

See attached Tapped horn hornresponse parameters. Anyone able to get rid of the bottom
bump? The compression ration is around 3-1, not sure how stiff the cone is on these drivers.
Anyone have any experience with this or other B-52 units?

Reduce S3 (to around 1600). Also has the advantage of making a much smaller box.
No idea if that impacts how practical the build is, or the suitability of those drivers for TH use though, sorry.

PS - not sure if you know this yet, but only model in 0.5Pi if you're sure you're going to be corner-loading it.

HTH,
David.

Either increase L23 or decrease S3.
