Need Help, 15" Q

[Gunlex 10+ year member]

Im under space constraints..I'm making the heigh only 15.5", and going to have a chamfer on the top and bottom panel around where the sub is, thus allowing it to fit. I have figured that i can go with a depth of 22" and a width of 32". I figured out using the RE website taht the volume would be 3.788 ft^3 with a Freq of 29.68.



Dimmensions:

H - 15.5"

W - 22"

D - 32"

Vol - 3.788 (3.6 after displacement)

Freq - 29.68

Port width - 4"

Port Length - 15"

Total port lenght - 39"

Is this looking good? The site says 2.8-4cu ft and 28-33Hz. My main concern was the phase of the box...I was told the phase was going to be a little off...

If you knew that program could be off, why did you use it? WinISD is free and takes 3 seconds to download.

I can't check for you at work but I think it looks good. The dimensions are very close to my Fi Q 15 box which is 3.5 cubic feet at 33hz.

Also the inner diameter on a 15'' Fi Q is 14 1/8'' so make sure you build your box in a way that you have the full 15.5'' of height on the front panel.
