Dayton Ultimax UM15-22 Winisd Help

I am a complete noon when it comes to modeling software. I have tried entering the parameters many times following various guides online. Either the program comes up with calculated values that are way off or it returns an error saying that the entire values do not match. Please help. I'd someone has already used this sub in Winisd and could provide me with the values you used that would be amazing. Thanks so much!

Hi Matt,

T/S parameter programs, like WinISD will give you free space (anechoic) various simulated frequency responses, for whatever data you enter...and desired box size, port tuning>F3, etc.
The PE site lists for that driver:
Quote:
Vented 6.0 cubic ft. (net internal, not including driver or port volume) with 6 lbs. of Acousta-Stuf tuned to 18 Hz with two 4" diameter by 26" long flared ports for an f3 of 22 Hz. Larger cabinets and lower tuning frequencies are possible.
So the question is, before any sim is run, what do you desire in terms of box size, anechoic extension (F3), etc. etc? Power input and handling are factors also. As are what size room, music and/or HT, how loud, etc.

cheers

AJ

You will find in WinISD that if you leave some of the values blank they will autofill and 99% of the time are identical to the T/S parameters. I had trouble getting it to accept the drivers I was entering but if I went back and deleted a few of the specs I manually entered and let it autofill then WinISD would accept it. Good luck!

Use the guide here to enter the T/S parameters in the right order:

And use this version of WinISD:

http://www.linearteam.org/download/winisd-07x.exe

Since the code base is dead, I started a project to re-create it with jRuby/Swing. But then it got hard and I got tired and that was that . But I did mock up a pretty sweet GUI before I quit though. Ah well...

Greets!

Where is this documented? I've seen several folks over the years state this, but it doesn't jive with what I know about the different boundary loadings.

TIA,

Hi Greg,
I think you might have misread what I said above, which is the sim shows various free space (un bounded) responses, with different box sizes, tuning, etc.
I don't use boundary sims (with the possible exception of xlbaffle), I simply measure in room.

cheers
