    Hi everyone,

    Would like to know what is the ideal enclosure sizes for the TD12M 8ohm? Both ported and sealed.

    Thanks much!

    It depends on your application.

    There is no specific set size. It is more what is best for your application. For a vented enclosure though I typically go with about 1.75 cubic foot tuned around 57hz. For sealed enclosures I typically go about .75-1 cubic foot.

    Thanks for the input guys. I am looking to build a pair of mains to cross over with my sealed subs at around 80hz.

    I will plug those numbers in WinISD and see what it comes up with.

    I tried .71cf and that gives me a QTCvalue of 0.702 and f3 at about 110hz. Would you say this is ideal?

    This looks pretty good and should blend pretty well to the subwoofers. If you want to get lower than vented is the best option. I like to tune lower than the crossover frequency by about 1/2 octave to keep the rise in group delay out of the intended bandwidth were it will be used.
