Need help with box real quick. Got T/S specs and $$

[528hz 10+ year member]

Ok...I need to get this figured out before tomorrow so I can build it, and I'll PP $5.30 if someone will help me with this.

I've tried to use winISD, but I can't input all the numbers because I don't know all the data yet (port displacement, and a few missing T/S numbers).

This is the deal:

I'm going to be running 2 of PSI's new 12s" in a 4-4.5 ft^3 box using one 6" aero port tunned to 30 hz (so I assume). I've got the T/S specs, but some of them are missing that winISD is asking for so....

I just need someone to plug these T/S specs in (if applicable) and tell me what would be the optimal size box and tuning for these subs.

Can anyone give me a quick hand? Here are the T/S specs:

Revc = 3.4974 ohms

Fms = 29.3385 Hz

Zmax = 38.5164 ohms

Qes = 0.5298

Qms = 5.3046

Qts = 0.4817

Le = 3.7342 mH (at 1 kHz)

Diam = 254.0000 mm ( 10.0000 in )

Sd =50670.7504 mm^2( 78.5398 in^2)

Vas = 54.1766 L ( 1.9132 ft^3)

BL = 15.5274 N/A

Mms = 198.1218 g

Cms = 148.5362 uM/N

Kms = 6732.3677 N/M

Rms = 6.8849 R mechanical

Efficiency = 0.2427 %

Sensitivity= 85.8678 dB @1W/1m

Sensitivity= 89.4613 dB @2.83Vrms/1m

 

 

The displacement of the 12" would be .17cuft

4 cubes w/ 1x6 inch port at 16.75 inches long = 30 hz good luck shared space no divider.

So are you saying "no divider"? This will be one chamber, yes.

But...my main concern is differences in tuning from 30-32 hz, and if that 4 cubes should be after or before sub & port displacement? That's why I would like someone to run the graph.
