    ...and can it only be done to SVS subs?

    I have a Velodyne CHT-12 and I wouldn't mind tuning it a bit lower, and getting this extra 5 hz [​IMG]

    What is it and can it be done?

    Tuning is based on the size of the enclosure as well as the diameter and length of the port. Every ported enclosure is tuned to some specific frequency based on the above conditions.

    The only way you could lower the tuning of your sub would be to lengthen the port.

    It could be done to other subs but would require you to physically change the enclosure. As far as I know SVS are the only subs designed with port blocking in mind so it's easy to do.

    You can tune some of the SVS subs by putting in a port blocker and changing a setting on the built in amp!
    but nothing is for free you will loose some output!!

    I don't know if Velodyne Subs have this option!

    The Hsu VTF series subs allow you to change the tune of the sub by plugging one of the ports and switching the filter setting on the amp.
