Wil Kelchner's Experimental
Sim of a Linked 3-way Series Cross-Over
(email from Wil)
Hi Andy,
I spent a while tracing
in the graphs from the Vifa site, and then simulating the series
circuits using Speaker Workshop. It seems to model ok, computer
didn't smoke at all, lol. I do not think this is a very accurate
way to design, it ignore too many things to be accurate. Still,
its interesting to see trends.
Data used were the
published frequency and impedance graphs posted on the Vifa site.
Data was 'traced' using SPL Trace. Traces were imported and .frd
and .zma files into Speaker Workshop. Circuits were modelled. Screen
captures were converted into .jpeg files.
Please remember what
kind of data we are dealing with here. Vifa measures there drivers
on an 'infinite baffle' so there are no room effects, cabinet effects...
Also, this simulation ignore the driver placement and offset...
You can begin to see why this only gives a glimpse of what is happening.
Wil....
(Andy G says) This
is the final version of the cross-over after "tweaking" at the "chat"
site and through email. The values correlate very closely with values
as calculated by the spreadsheet.
THANKS HEAPS WIL
