    Any tips for testing that a sealed subwoofer is

    airtight?

    I have the exact same question. I read somewhere that you should run a 10 Hz test tone at moderate levels. Then move your fingers along all the eges to feal for any air moving out. I did this but I don't know how well it really works.

    One I read was to hold the edge of a tissue and move it along the seams.

    Probably NOT a good idea to use 10Hz test tones unless the woofer is VERY stout one. Try 30-40Hz instead.

    Push the cone in and see if you can hear any hissing.
    A 2-5hz tone will do the same thing though... just be careful when you do it [​IMG]
