Ok I've been playing around with WinISD pro (free and awesome program - I like it better than bassbox pro 6) and I'm modeling a fullrange $10 HiVi B3S in a 5L vented enclosure tuned to 70hz. Here’s what I came up with.
Raw modeled response:
After highpass @ 55hz and EQ work at 150hz:
Here’s the excursion at 15watts:
So, according to WinISD this speaker would have flat response down to around 65hz while staying within its capabilities of 3mm xmax at 15 watts. I know it won't be that loud (WinISP says 93 [email protected]), but could be good for computer speakers.
I have a few questions.
Will the SQ suffer when you model something with peaks and eq it down vs. true flat response?
How accurate is this software? can I expect the real speaker to be anything like this modeled response?
Anyone see any flaws in this design?
Thanks,
Jeff
