Subject: Exponential Ports


How do I model a 4th order BP with an exponential port? I would like to turn the attatched box into a 6th order BP by porting the sealed chamber. The lines are labeled with their lengths and the chambers' areas. The height can be anywhere from 17-19 inches.

I want the port placed at the very end of the horn-looking flare.

What size port should I put in the sealed chamber so that the front and rear waves sum together completely?

What programs can I model this type of enclosure in?

Or how do I use a program suck as winISD to model it?

If anyone could suggest a heighth and tuning frequency along with port dimensions I would be very thankful.
