It would be something like this:

Width= 24.00 inches

Height= 24.00 inches

Depth= 25.50 inches

Port Length= 36.73 inches

Driver Volume= 5.02 cu/ft

Slot Vent Width: 3.25 inches

Wood Thickness: 0.75 inches

That would be something like 5 cu/ft @ 30Hz with a slot port.

so port would be 3.25wx24h

right guys

 

[rpfuror 10+ year member]

no you have to subtract the wood so the height would be 22.50"

If you're going to be playing movies on this home setup, then 30hz is going to sound like ***.

1 x 4" port = 4.5"
