Need help tuning a box.

carshateme · 11:49 PM

Well I like to "create" boxes on my 3d modeling program before I build it so I know the exact measurements of each side...

SO here's what I'll be working with

*3/4" MDF board, learned 1" MDF is way too much.

Here's the specs for the subs I'll be getting in a few weeks:

RE: 7.09 Ohms
Fs: 28.4 Hz Hz
Qes: 0.511 0.519
Qms: 5.75 7.25
Qts: 0.469 0.484
Vas: 40.3 L
BL: 25.04 NA
Le: 7.7 mH
Mms: 252 g
BL^2 / RE: 88
600 watts RMS
XMAX: 19mm one way

Mounting Depth = 6.5"
Cut-Out = 10 15/16"
Displacement = 0.14 ft^3
Overall OD with Gasket = 12.5"
Enclosure Suggestions:

1.75 ft^3 ported tuned to 30 Hz -- F3 of 26 Hz
* Tune higher and use a smaller box for more SPL oriented setup (Use 1 - 1.5 cubes)
* Enclosure can be as big as 2.25 ft^3 with lower power levels

1.00 ft^3 sealed -- F3 of 44 Hz
* For SQ and space limited applications

*I'll be using the subs for everyday bass/SPL sometimes.

IT WILL BE PORTED.

I would rather have slot ports instead of circle ports, but if circle ports are better...I'll go with them. Will appreciate any opinions.

Just need the port length...for I have no clue how to do it...I'm just good at dimensions and such...

Max dimensions are 33"w x 13.5-14"h x 15-26"d

Will probably want 1.5cu volume for each sub....whatever produces more dB

*I'm new to this. I only won one SPL competition in the summer, got lucky.

The box I designed you previously will work fine for these too, I just modeled it and all works out ok.
