Phase Plug, how does it works?

Antonio · 17th June 2009, 08:21 AM

Hi all!

does any of you know how a phase plug works? I'm tolking about phase plug on a conventional cone driver, not the one mounted in the compression drivers.

Could you suggest some interesting reading about?

Thanks,

Antonio

I use Henricksen’s AES reprint #1328 as a guideline for my own radial phasing plugs. Both radial and circumferential phasing plugs get the job done, but I find the radial to be a better choice for me. If you use a ridiculous complicated passive crossover that swamps the tone of the cone driver, then you can use either. However, if you use line level crossover or a minimalist’s crossover and want to retain the tone of the cone driver, then the radial phasing plug is far superior.

You should also look at Bob Smith’s AES reprint #1384. Another thing to look at is JBL’s Tech Note Vol. 1, Number 30. It covers their cone midrange compression drivers (CMCD). It doesn’t matter if you use a dome or a cone, the principles involved are the same.

Hi JLH,

thanks for your replay. I was looking on internet for Henricksen’s AES reprint #1328 and for Bob Smith’s AES reprint #1384 but I was not able to find it. Do you have it? Could you please send me with an e-mail?
Thanks again for your help.

The only on-line link to the Henricksen paper is below.

There are also more related things to read in the Beyond the Ariel thread. See post #3389

I don’t have an electronic copy of Bob Smith’s paper. I just have a printed copy of it. You can find the JBL Tech Note on the JBL Pro web site under their library.
