The traffic in subwoofer related posts seems to be increasing, short of exponentially but impressively none the less. Perhaps a topic who's time has come. It does not fit neatly into Bo's wonderful "Lansing Related Gear" section, as much of the posting is about JBL drivers, but what the heck.
It is not just DIY, but also usage, theory, market price and tweaking inquiries and FYI's that seem to be on the rise.
