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.
