Home Speaker Asylum

General speaker questions for audio and home theater.

Dunno 'bout IKEA--kinda doubt it. Here's my straw technique:

The above image is a 5-inch two-way in a 10-Liter cabinet, with a Precision Sound Products double-flared port kit, and a straw-stuffed port.

I start out with a bunch of straws that is larger in diameter than the port tube. I then do a test fit and remove enough straws so that it is a comfortably tight fit.

Then I take the kind of elastic band that the supermarket uses on broccoli and put that around the near end. I then add straws from the opposite end, one at a time and test fit until it requires some effort to get the whole bunch of straws halfway into the length of the tube.

Then I take the bunch and even it out by rolling it between my hands and then pushing one end down on a table top and then the other, and then carefully push it in (using the base of a jar or a drinking glass as a pusher) until the port is stuffed, but there remains enough of a fingerhold on the elastic band, so that I can pull the straw bundle out, to show visitors what the difference is.

(NB: The above photo is different because it's my design and the rear panel is removeable, so I can adjust and straighten out the straws from both ends of the port tube.)

I actually sent a bunch of straws in an elastic band to Morel USA, and they never got back to me. "Not Invented Here Syndrome," I guess.

I'm sold on the idea, which I stole from the ProAc of 35 or so years ago.
