Hello:

Can anyone point me to an article that discribes the procedure and test equipment needed to tune the port of a speaker/box.

Thank you,

Bill

Here's some quick and easy stuff -

Impedance Analyzer (http://www.danmarx.org/audioinnovation/impanalyzer.html)

Elliott Sound Products (http://sound.westhost.com/tsp.htm)

Look for a new version of the "Woofer Tester" from Parts Express sometime in the future. The old version does pretty much "everything" found on Rod Elliott's site automagically and dumps the data to flat files.

Oh, and then there is this - JBL Enclosure Information Manual (http://lansingheritage.org/html/jbl/plans/1979-manual.htm) - the last few pages tell the tale.
