remaining box specs for Kappa 120.9
 

Hey guys.
So I have been putting together a SQ system for my daily driver 2000 mustang. I have the new Infinity Kappa 120.9w sub in the mail and I would realy like to build a nice box to get the most out of her. My current plan is to build a sealed box for now, mainly because I have only used ported boxes in the past, so I thought it would be fun to try. I have been trying to build a box on WinISD but im not sure that I understaind all of the required specs. So far I have found.

Vas: 54.43 L
Fs: 27.2 Hz
Qts: .46
Re: 2.1
Le: 1.18
Xmax: 17.5
Qms: 4.38
Qes: .51
BL: 12.87
Dia: 305mm

The specs that I have yet to fill out are
Z, SPL, Pe, and Sd

I was able to find a link to the sub manual that provided me with most of the information http://akamaipix.crutchfield.com/Manuals/108/1081009W.PDF

Also i was wondering what thickness of MDF i should build with?
Thanks!
