WinISD - Sonosub Cone Excursion Graph

Can WinISD calculate the cone excursion for a ported sonosub enclosure? I have attempted do calculate this, but the excursion data seemed awfully low (i.e. .05 inches).

Yes it can. What sub are you modeling?

Re: WinISD - Sonosub Cone Excursion Graph

I am just in the learning phases about WinISD and Sonosub. At some point I would like to build a sonosub or a ported sub. I have been playing around with the Infinity Kappa Perfect 12.1 in WinISD and have also entered its specs into Sonosub.

Also, how do you calculate the optimum volume of a sonosub? Is it by the driver to box top resonance that you would like?

WinISD clalculates the optimum volume for a given application. ( music, HT, or both). After that's figured out Sonosub.exe will figure out the proper size of sonosub and porting depending on the specs you input from the WinISD modeling.

Thank you, that helps alot. I was doing things backwards. However, WinISD is setting the tuning freq. to 20.96. Is this due to the fact that the Infinity is a 12" driver? I see alot of people tuning to ~15 with 15" and 18" drivers.

Re: WinISD - Sonosub Cone Excursion Graph

WinISD calculates what it thinks is best according to the parameters of the sub. Box size and tuning can be changed according to the subs capabilities and what your needs are. Are you thinking of a HT sub?

Yes this would be for 99% HT use. The sad thing is that I have only had my BIC H100 for about 3 weeks and I already want more low end :P

I like how easy the sonosubs look to build compared to a ported box, and the reason I was modeling the Infinity Kappa Perfect 12 was because I would like to minimize how wide of a sonotube I would need to use.

Do you have a link to the Kappa Perfect 12 T/S parameters?

The last page has the specs. I am open to better 12" driver suggestions as well, or even 15" drivers if it's possible to mount those in a 20" sonotube.

Re: WinISD - Sonosub Cone Excursion Graph

How much do you want to spend on a sub? What are you going to power it with?
