Manufacturer's Specs: Boston Acoustics G5

[SV.Gato 10+ year member]

I could use your help, yesterday I received my Boston Acoustics G512 DVC 4OHM sub. I am ready to start building the box but a bit confused by the manufacturer's recommended sealed box specs as follows:

Model: G512" G10"

H = Height: 10.5" (26.7cm)

W = Width: 13.0" (33.1cm)

D = Depth: 13.0" (33.1cm)

Gross Volume: 1.0 Ft3 (28.3L)

Q-Tune™†: (HP & Q) 28Hz@0.707

-Enclosure dimensions are internal and include basket displacement

-This enclosure shape is an example and these dimensions can be modified provided that the exact internal volume is retained.

-3⁄4-inch thick M.D.F. is recommended as a minimum

-†Q-Tune™ is a feature found on Boston GT Amplifiers

I am confused because when I load the dimensions into the12volt.com volume calculator, I get a total volume of .86 Ft3. This is completely without thinking about basket displacement. If I read correctly, the first bullet says that enclosure dimensions are internal and include basket displacement. Would someone please double check these figures and see what they come up with? Thanks!

Those are internal dimensions, not external.

The internal volume before sub displacement is just over 1 cube. After sub displacement it will probably be close to .85 cubes.

If you make that box, make sure to add on 1.5" to the height, width, and depth.
