haha - hornresp has amazing mobility. Is there a very early internet version stored somewhere on the web?
- wonder if aperiodic technique was documented before this 1935 patent? - that doesn't sound far back as I was born in 1950

Hi Fred,
Wait until you see your "sidebranch absorber chamber" option, in the next release....
Not that I am aware of, but someone may have archived a copy. I do however have the fifty-year-old deck of 80-column Hollerith punch cards containing the original Fortran IV source code.
It's even less far back for me....
I wish!.
Kind regards,
David

Hi Thawach,
If you are asking whether the complete system can be simulated as simply a bass reflex box (shown in red in Attachment 1) radiating into Ang = 0.5 x Pi because the blue-grey "back panel" portion of the cabinet serves as a corner, then the answer is no.
You would need to come up with a model for the complete system, including the back panel portion, radiating into (half?) space.
Fred has suggested one possible model using four stepped segments. I doubt that it would help in this case, but note that you can specify up to 6 segments if necessary, by including front chamber and Cyl throat adaptor components together with 4 segments (stepped), as shown in Attachment 2.
Kind regards,
David

Hi Fred,
My trusty old HP Compaq is more than powerful enough for me at this stage, thanks. I tend to only upgrade when I am forced to. Setting up a new computer with a new operating system, and getting everything to work as I want it to, particularly the Visual Basic programming application, is quite a traumatic experience for me
.I am a great believer in "letting sleeping dogs lie" and "if it ain't broke, don't fix it". Come to think of it, I also quite like the Hogwarts School of Witchcraft and Wizardry motto:
"Draco dormiens nunquam titillandus". (Never tickle a sleeping dragon).
.Kind regards,
David

Just to clarify - I am saying that having two extra segments would probably not help in this case, not that using Fred's suggested model would not help
.
As for Akabak, on a virtual machine (wine on linux or else), hornresp will run forever ^^
like so? - - - (tell me how you you sim those fabulous Karlson-ish cabinets)
Exactly!

thx u freddi i might not follow the hornresp very long time. i hv just known the hornresp can sim the difference segment. about karlson i had ever seen ur post. i saw the freq respond from u measured. i sim as the same bp. and i tried to understand the effect of the front panel. and drew them until it was finish. i have one karlson design that i still not finish. it s karlson line array if it is finish ill tell my friend measure them.
