Hello! I'm from Russia.
I designed own basshorn 2х15" on EighteenSound 15lw1401 drivers.
I conceived to perfect 40hz basshorn WSX with more compact size and bigger length of horn to get more SPL in 40Hz with smaller displacement of diaphragm.
I think i got it... Wink

My plans and graphs:

While this construction is not made.
I have not so much time yet to build it. And i'd want to see your comments or your built.
Wink

Good work! the plans and models look good.

but i agree with the above comments..

1) you should always model in 2pi
2) Your box is shape isn't practical. One of the dimensions needs to be <70cm.

How practical is a small throat on something like that? Will the compression ratio be too high?

Not many 15" drivers have the Xmax, BL, or Cone properties to handle 2.8m horn, from 40-80, at > 500W input.
 
What did you intend to use ?
