I suspect no one has answered yet because its hard to understand your question. Depending on the which of MJK's worksheets you are using, you normally input the driver T/S parameters, input the xover params (some worksheets), input the enclosure params, etc. and the response characteristics are generated.

MJK has a forum at yahoo.com called "quarter-wave" that you could join and ask the question there.

sorry for the confusion.

if you look at this picture, there's a blue dotted line (as with all graphs), what is the significance of this plot vs the plot for that box. is the ideal for any design to try and hold close to blue line? or is it just a handy comparison?

I believe the blue line indicates "infinite baffle" comparison with the same driver.

yes it is, but should your aim be to match that ultimately?

Most emphatically NO!

It's there as a reference so you can see how much better the TL, MLTL, horn, etc. is than the basic performance of the driver.

Cheers, Jim
