The Homewrecker subwoofer system (how-to)

This is fantastic. I'd heard of cutting a hole in the wall for this purpose, but I'd never considered using a doorway, which is both less permanent and more attractive.

It's brilliantly simple. The best kind of brilliance.

I read an article once about a company that invented a "rotary subwoofer" (link below, if you want to see it) that actually uses your entire attic as a baffle. It seems that because they don't use a cone, they can actually get down to something like 1-3Hz...though I'd think you'd feel that more than you'd hear it.

For anyone that wants to get a real subwoofer (one that extends to 20 hertz), I would recommend http://www.hsuresearch.com/. I would also recommend his satellite speaker system, it's basically the anti-Bose.

I second this recommendation. Hsu makes great stuff with out all the flash that adds to the price.

From the site:

"I have not yet fully tested the capabilities (or potential dangers) of this system. The heating and cold air return ducts in most rooms in a house should be enough to relieve the pressure induced by large woofer excursions. However, if there are no ducts in a room for some reason and there are windows, be aware of the effect of the pressure on the window(s).

Very low frequencies travel well and are not easily absorbed, so if you are using this system at full or nearly full capacity and have immediate neighbors, they will hear it and probably call the police. Use good judgement ."

Nice.

Perhaps my age is showing, but I wonder why anyone would want such a thing in his home. The instructables site is quite annoying, btw. Lots of ads and really poor design.

I wouldn't want it in my home. However, pointing out the front door of a nearly-finished construction site/abandoned building...

Why would someone want to go and write their own compiler/text editor/OS/blog/foo? For the sheer joy of hacking :)
