I have enough problems building regular ported boxes. I dont need some einstien coming up with a louder alternative and making me have f!ck up even more trying to build his space station for a subwoofer.

From my understanding of enclosures, there is no real "horn" there. A spiral would just allow you to have a long port in less space. All of his speakers look like ported enclosures to me.....

thats crazy, but seems like a great idea if your short on space and have a lot of time on your hands

/me cues the redneck explanation.

The spirals make the sound go faster.

The technique to make it a 'horn' is that with the spiral port, the mouth's spiral is more apart than the throat and the length of the spiral makes up for the massive displacement of say, a folded horn.

I'd say it's a mix of a transmission line and a flared port. I don't even remember how I came across it. If you could find a spiral like that you didn't have to make out of 100 or so cut pieces of MDF, it'd be quite easy to make. Just do a PVC normal ported enclosure and glue the spiral in it.

There's a lot of math in dem dere spirals.... Actually, if you look at all of his enclosures, they use some kind of ribbed mat for spirals, not wood. That way you wouldn't have to cut anything.

Making the spiral wouldn't be the pain - sealing around the outside would.

DUH! look at the spiral... the distance from one "thread" of the spiral to the next "thread" is constantly getting larger. GGPWNDKTHX

Actually they made the spirals several different ways - the site is really worth a good read.
