I was gifted two Eminence 12 inch OEM subwoofers. The subwoofers were manufactured as a proprietary custom OEM design for an Eminence customer. Eminence does not offer cabinet support for OEM product.

I would appreciate any help deciphering the attached spec sheet and any advice thoughts given on a sealed or ported subwoofer cabinet design. I tried running the numbers in various calculators but it seems the needed values do not concur with the values provided on the spec sheet.

What i need is Qts, Qtc

I would like to build a cabinet that fits both subwoofers with the emphasis on sound quality for a home theater 7.1 setup.

Thank you for any and all input.

It might look like a Lab12, but the specs are a bit different. Looks to have higher inductance, a stronger motor, and a stiffer suspension. You can plug this data into WinISD and model away. I've attached the wdr file from entering this into WinISD.
