Help building sub vent
I am trying to build the correct size retangular vent in my sub box. The specs per the sub manufactuer are listed below (in metric units)
Reflex Box
Vb= 28 Lit
Fb= 35 Hz
Reflex Tube
Ø= AR 65V
L= 155 mm
Does this mean the port needs to be 6 3/16" long with a 3" surface area (1.5" x 1.5")?

Not sure why you multiplied by 6.... the length has nothing to do with port face area.... only time you need that is to calculate how much space the port is taking up in the enclosure or tuning frequency.

[QUOTE=DeadlySones;635496] IMHO that is a pretty small port, even for a box that is barely 1cuft.
This was the reason for my OP. It seems like a very small port, but the info in the OP is copied directly from the box specification from Hertz.
