Default (2) W18E-001 Cabinet w/Port

Hey everyone - sorry to post something so simple but there is so much information I can't seem to locate an answer...

I need to calculate a cabinet volume and port with the referenced woofers. Seas website has (1) W18E-001 in a 25 liter with a port that is 5cm X 15.5cm or 6cm X 23.2cm...-35Hz at -3db.

I'm open to a 3" port because I plan to make these floor standing but I always assumed the port would be longer but when I calculate it I'm getting something like 3" X 6.6125" (sorry for changing units)...is this correct?

Anyway, can someone who is a little more experienced suggest a volume and port size that will have a low cut-off frequency that the speakers and port can handle.

Thanks for any help!

Using Hornresp to vet the specs, plot a sim and this box calculator, a 28.45 L net tuned to ~34.4 Hz requires a 13.843" long x 3" i.d. dia. pipe: Subwoofer Box Enclosure Design Calculator - Sealed Ported Bandpass Closed Vented

Using the published Fs, Vas, Qts calcs a larger 33.1 L / 32.9 Hz / 12.82" long x 3" i.d. dia. pipe, so the one to use when there's no measured specs and even then may prove to be too small, though Seas specs tend to be pretty accurate.

Loud is Beautiful if it's Clean! As always though, the usual disclaimers apply to this post's contents.
