    It might be a bit old but I've just come across this article:
    http://hometheatermag.com/subwoofers/3/

    Which covers the fundamental priniciples of subwoofer design and placement in nice simple terms with helpful diagrams. The last page also outlines the differences between sealed and ported subs.

    Hopefully it will enlighten someone. :)

    It is a basic rundown not bad for beginers but still quiet generalised in each area.

    There bit on Hoffman's iron law is a bit thin they could have explaned the relationship between.

    Enclosure Size.
    Power Efficency.
    Depth (Frequnecy response).

    You can pick 2 but have to trade one, there is not a way round it.

    IMO a better guide would have as well:

    PR - Passive Radaitor designs.
    IB - Infinate Baffle installs.
    Isobaric loading.
    Added EQ/boost advantages/disadvantages.
    Subsonic/Rumble low highpass sub/infrsonic filters.
    Reference levels.
    Power Compression and the effect on frequnecy response and reduced dynamics.
    Driver power handling themal and mechanical.
    Bass Management.

    I think it was intended to be a rudimentary rather than exhaustive guide.
