Box Calculation Help
ok, so i just ordered my new subs, i ordered the new Fusion NV Series 15's, Got one now and the others gonna be a month or so...anyways, i need to build a box, or have one built in the GTA(any takers pm me with a price, Id Rather this done right)...i will be running just one 15 for a while untill i gte the other one, and a freind of mine built the box for the 2-15's already but hes away for the next 3 weeks...and as u can imagine im anxious to gte this running....Anyways, Here are the Specs:
Subwoofer Parameters NV-SW15
MAX Power Rating (Watts) 2500
RMS Power Rating (Watts) 1100
Coil Height (Hvc) (mm) 40
Compliance (Cms) (uM/N) 146.18
Cone Area (Sd) 77.93
D.C.Coil Resistance (Re) 0.88
Electrical Q (Qes) 0.552
Force Factor (BL) 8.4
Free Air Resonance (Fs) 23.62
Frequency Response (Hz) 19Hz – 500Hz
Gap Height (Hag) (mm) 10
Impedance (Nominal) 1
Inductance (Le) (mH) 0.51
Linear Excursion (X-Max Total) 40
Mechanical Excursion 15
Mechanical Q (Qms) 6.17
Moving Mass (Mms) 285.85
Sensitivity (dB) 87
Total Loudspeaker Q (Qts) 0.506
VAS (Litres) 126.07
VAS (CuFt) 4.45
Magnet Structure (Oz) 308
Total Loudspeaker Displacement (Litres) 12
OPTIMUM ENCLOSURES (All enclosures include port and subwoofer displacement. All ports are circle aero ports unless otherwise stated.)
PORTED NV-SW15
Volume (litres) 106.4
Volume (cu.ft) 3.759
Port diameter (mm / in) 101mm / 4"
Port length (mm / in) 289mm / 11-3/8"
Tuned frequency (Hz) 26.2
my problem is if i have to build this myself, how do i figure out the port(i would be making a slot port if possible)...For Anyone That wants to tackle this My only limits as far as The Max Box Size is:
18" Tall (max outside hight)
38"Wide (mabey a little extra)
24" Deep (little extra)
This is for a daily driver as well....Sorry about the long post,Any advice or ideas is greatly apreciated, Thnx in Advance

not sure what your question is.
Your post clearly gives the box and port dimensions.
What additional information are you looking for?
Will the box fit in the car? Will 2 boxes fit in the car?
Will you be able to get the box in and out of the car?
to calculate dimensions
inside hxwxl in inches is = total cubic inches
1 foot = 12 inches 1 cubic foot = 12x12x12 cubic inches
So you need a box = 3.75cubic feet= 6480 cubic inches
Why do you want a slot port instead of a round port?
