Default Small Passive TL?


I was wondering what would happen if I put a small driver, say 4" up against a length of folded 4" diamiter drainpipe. If it was tuned to 20 Hz, (4.25meters long at a total guess, hidden behind each sofa?) would it help out my home stereo when 2 of them were wired into the left and right second channel? I could put a filter before the speakers. Or would it just not work at all?

You can tune the box to anything you want, but a 4" driver isn't going to produce output at 20Hz. It will probably destroy the drivers.
I was so much older then, I'm younger than that now.
