    Subwoofer Box specs

    Is there anyone out ther that would be willing to figure out the box volume I should have and port size and length for 3 - 8" kicker subs as I am not very good at designing ported enclosures.
    Thanks for any help or advice

    -fs = 44.3 hz

    -qms = 9.36

    -qes = .912

    -vas = .495 ft3

    -qts = .831

    Those subs will need a huge amount of volume in order to sound good in a ported box. If you already have them and can't return them, consider a sealed or 4th order enclosure. If you haven't bought them and space is an issue, consider the SA-8 from Sundown or some other 8 that has an EBP above 60.

    The specs you list indicate an EBP of 48, while the SA-8 has an EBP of 83, iirc. To calculate EBP, divide Fs by Qes.

    O.k. I already have the subs so I think I will just run them sealed, what size box would be best for sealed?
    Kicker suggest .4 all the way up to 1.8 , do you think they would be good in .75-.85 per sub?

    That should be fine. I'd go as large as possible if you're interested in them playing low.
