Very impressive guys!

What are the dimensions?
What is the knee?
What driver was used to model?

Great execution on a concept!

hi stanley
its only a model.im gona bild this next time(test box),but it should work with most modern pro 18 inches qts 30 to 40 and vas 175 to 300 ltr.

now the folow up on this design.
i finaly had time to do some measurements.
here are the results
measured with uncalibrated beringer mic.
use arta and limp sw.
indoors close mic.

as we can see the horn is in reality shorter then simmed.
i used the white line ,but i think i should measure the red line.
in the hr sim the grey line is like the white line in the model ,and the red line in hr sim is what ive measured looking /comparing the imp graph.
it sounds good but not a flat to 30 sub(more flat to 40).

btw the shopped off first imp peak is due to either the sw or the elcheapo external usb soundcart i used.

edit/ this box was not designed for the 18sound lw 1400,but i had this one close by
