    DIY Subwoofers - General Discussion
    For a while I've been trying to wrap my head around stuffing vs lining. My understanding is that typically a ported sub should be lined and a sealed sub stuffed. I have seen some recommend stuffing a ported sub (perhaps taking quality over spl?) -- using less than 100% fill (Kevin Haskins...
