New Speaker Design Excel Spreadsheet

...only it's not one of mine. It was made by Scanspeak to include their new speaker parameters in a more complete box model. It's kinda interesting. It can be downloaded at this link:

But Scan-Speak's T/S parameters are grossly off from the spec sheets (though consistent from unit-to-unit).

Yes. And isn't that frustrating? SEAS isn't much better sometimes. I had a pair of Excel W18 woofers that measured an Fs of 54Hz instead of the advertized 40. That's pretty far off for $400 worth of drivers. Both these guys could learn a lesson from SB Acoustics, whose drivers have all meausred almost exactly on spec for me.

Still, the spreadsheet is interesting for anyone who likes that sort of thing. ;)

... or HiVi, for that matter. Theirs have been pretty much spot-on for me.

I took a quick look, but no thanks. I'll stick with Frequency Response Modeler and PCD.

However Jeff, I don't think you have Danish versions of your spreadsheet tools...:p

Uhh...This is a box modeling spreadsheet, nothing in common the two that you mention. You would stick with Unibox and WBCD then? ;)

This looks very interesting. I like the description of how it is more accurate at simulating suspension and damping, so perhaps the simulation below the port tuning frequency will be closer to reality. I will have to play with it a bit and see. Too bad it cannot simulate passive radiators.
