What are my ported midbass pods tuned to?

[BassAddictJ 5,000+ posts]

Each pod is 2 Liters (0.070629 ft³) before displacement, with a downward firing circular port. Port diameter is exactly 2in, and the port length (thickness of the fiberglass it's cut in) is exactly 1/4in.

I used this online calculator:

Subwoofer Vent Minimum Port Diameter Calculators - Maximum Air Volume, Number of Ports, Tuning Frequency

and did not get the answer I was looking for....

somone enlighten me

pics of aforementioned pod (which could use a lint roller cleaning)

blue stuff in the port is leftover foam that was glued into place making these pods sealed previously. i plan on cleaning that area off and possibly resealing the port depending on what info i get here.

Does not look like a port to me. Looks like a whole cut for some other reason and never fixed.

that is a hole, not a port. you need some length to that.

i'd just close it up unless you intend that to be a vent to outside of the vehicle.

According to BassBox Pro 6...with ur ^ft and hole diameter, its 236.5hz....looks like a hole to me though if its firing into the floor....

Before you seal them up ever consider venting them into the a pillar cavity or some sort of cavity behind the kick panel metal? I have made pods alot like yours except mine at .2 cubic feet according to packing peanuts. I have hybrid imagines in them and they sound great, but when I had tried them in a cubic foot box with just a hole in the back for a vent they sounded 10x better. So ide consider venting them into the kick to give them more of an infinite baffle if thats what your speakers work best in.
