You need the T/S parameters to get the driver modeled.

If you post the T/S parameters, someone on here will get you set up with exactly what you are wanting to know.

Parts Express already did the calculations for that driver. Scroll down to see this:
Optimum Cabinet Size (determined using BassBox 6 Pro High Fidelity suggestion)

• Sealed Volume 0.1 ft.³
• Sealed F3 = 122 Hz
• Vented Volume 0.2 ft.³
• Vented F3 = 72 Hz (fixed that typo)

It seems to work best in a sealed cabinet with 0.1 ft³ internal volume.

Edit: My earlier typo (vented F3 = 372 Hz) clearly makes a big difference. Sorry about that.

and you're not going to get much bass out of it. Vented F3 for optimal size cab is 72hz
It's a tiny driver. Physics is a b1tch

Sorry about my earlier typo. It's now corrected.

You plan on using one driver in a 0.2 ft³ (5.66 liter, 345.6 in³) ported cabinet, right?

I played with the calculator here http://sbp.softica.dk/2.0/en/ and came up with a port 4.76 cm diameter × 14.68 cm long. In inches, that's 1.87" diameter × 5.78" long.

Buy a pair of these from Parts Express (part 260-476), use them without trimming, and you should be close enough.

Don't take my numbers as gospel. Because you bought the drivers at Parts Express, you can contact Technical Support to ask what they recommend.
