Measuring dipoles

Raka · 2nd September 2007, 09:29 PM

There is a way to measure the dipole frequency response, which consists of measuring nearfield in the front and back, apply a delay to the rear wave in accordance to the baffle efective size, and then add both. This works very well I have to say. And the error on the shelving is not high.
But, how you can be sure that the delay is the correct one? Is there any way to measure it?

It is easy to calculate empirically, but wouldn't the delay show up on a simple impulse response measurement?

Hello Raka,

John K has a nice simple write up for measuring dipole speakers on his site.

http://www.musicanddesign.com/measure_dipole.html

He has a lot of other good articles on dipoles which you might find useful.

Hope that helps,
