How is one supposed to figure out an acceptable port speed in a rectangular port? Using collo's "flare it" program, it's easy to tell what ports are going to work, but with a slot port, it's hard to tell if a port will work or not..

I'm no expert on the subject, but you can manipulate slot port parameters in WinISD Pro (but not WinISD online).

1. Download WinISD Pro - Alpha release (kind of glitchy when you attempt to close).
2. Select a driver or input T/S values (Qts, Qes, Qms, Fs, Vas)
3. Select VENTED box type.
4. Select ALIGNMENT of your choice.
5. After the frequency response is plotted, go to the VENTS tab. Click on the circle below SHAPE. This will toggle the vent to a rectangular shape and allow you to input H x W to yield port length.
6. From there you get port velocity among other very useful modeling information.

Hope that helps.
