hello diyAudio members.
I am buliding a stereo speaker box using the PS-95 driver. before i start building I am using WINISD to simulate the box. my issue is as shown in the imeg, the impedance is off the chart when i set a 3.3L ported box and a 88 HZ resonant frequency. on the Dayton Audio and Parts express sites it is marked as a 3.3L 73hz F3 Vented box... what am i doing wrong?

You have the limits on the chart set too low, the PDF for that driver shows a 72 ohm peak at 120 Hz.

This driver is not really suited to a reflex enclosure. The 3.3 litre alignment is kinda ugly, i didn’t even try to get somethign nicer. The other curve is 5 litres sealed.
If you want bass out of this one, you might look to Frugel-Horn Lite, or develop a TL/ML-TL. Should make. reasonable midTweeter.
Note that to humans F3 is meaningless. Look at F6 and F10.
