TB W3-665SC T/S par. (Logitech drivers)

[Chris8sirhC]

After seraching far and wide, i have not been able to find the T/S paramaters for the TangBand W3-665SC driver that Logitech uses in its computer speaker system. Does anybody have any clue what the param's are? Has anybody tried a project using these drivers? Here is a link to a thread about these drivers

My guess is that they are just custom drivers logitech specified from TB for their specific application.

If nobody knows, what equipment would i need to find out for myself?

Hmm you should be able to get T/S parameters using loudspeaker workshop and the wallin jig. I have not done this yet as I have had no nead to, but it can be done. The help file outlines a few ways that the program can calculate them from measurements.

If you build the jig and a mic preamp you will also be able to measure the frequency response of the drivers.

Also praxis, I think its praxis??, can measure T/S parameters, I have heard that it can do this with the demo version available for free d/l but I cant figure out how to do this. Prax is certainly not user friendly.

If you don't plan on doing a ton of testing, or just want to build something so complicated as the wallen jig, or just don't wanta spend the money.
There are instructions on making some dedicated cables here,

and nice detailed instructions on setting up and using speaker workshop.

I know this is a super old thread, but I have contacted TB for the spec sheet for the W3-665SC used in the Z560 speakers. I wanted to see if I could use the 4 drivers from my broke unit to make something worthwhile. TB was glad to provide the spec sheet, and was very quick with thier response.

The file is too large to attach, so I will post the specs, and you will miss out on the FR graph. The graph looks quite nice, btw.

DcibeL,

Is there anyway I can get the datasheet from you? I have quite a few of these drivers laying around and would like to do something with them. Please PM me.
