Goldwood GW-408D 8" Poly DVC Woofer
What are the optimal port dimensions to achieve the stated 32 Hz in 1.83 cu. ft.? Thanks in advance.
I would recommend a port that is 3" in diameter and 4" long for that F3.

I saw this answer down below: recommended sealed box volume for this woofer is 1.24 cubic feet or 13"x13"x13" measured internally. This provides an F3 of 63 Hz. ......Does that mean it starts dropping volume below 63 hz? But above that it's fine?
Theoretically yes. The F3 is the 3 dB down point where the driver starts to lose volume on the low end, but this number is based on models. In room (realistic) output will be lower than this depending on room placement.

Has anyone tried to use this as a 16 Ohm speaker by running the voice coils in series?
I have a subwoofer in my Lexus SC430 that is 16 Ohms......I am hoping to use this speaker with the 2 voice coils run in series to present a 16 Ohm load to the amp. Unless anyone knows where I can find an 8" subwoofer that is 16 Ohms....
You will be hard pressed to find a 16 ohm subwoofer without going to the dealer for it. This will work well for that application with the coils in series.

What's the optimal size for a sealed enclosure?
I want to build a sealed enclosure for this speaker? What would be the optimal size for this speaker? I've been online trying to find some calculators that would give a recommended size but i've gotten results from .60 cubuc feet to 3.5 cubic feet. I'm thinking the smaller is correct but i'm just not sure. Thanks.
The recommended sealed box volume for this woofer is 1.24 cubic feet or 13"x13"x13" measured internally. This provides an F3 of 63 Hz.
