Hi,
I can show you a list of 6+ websites (a ring, because they are all connected) distributors in Europe and World with parts made in China (and others) as an example. The graphics they show are "can't read" frequency response graphics that were originaly furnished by Motorola (or just copied). You are losing time. I give you an example to buy 15.000 of that such items from.Buy Obsolete Products here
(http://www.freescale.com/webapp/sps/site/overview.jsp?nodeId=010984007869597059286926661)
another (one) example of this service in Europe
(http://www.vdmais.kiev.ua/about_E.asp) I prefer to stay with an old style cone tweeter from West Germany, that you can find the curves for (some don't).
RTO cone tweeter here (http://www.elfa.se/elfa-bin/setpage.pl?http://www.elfa.se/elfa-bin/dyndok.pl?lang=en&vat=0&dok=9752.htm)
Best Regards

Check out these measurements I made of some different piezo a while back. The MPT-100 is a KSN-1038 clone, and as you can see, it isn´t as smooth. BTW, the KSN-1177 is still my overall favorite, I think it sound more natural than the KSN-1038.

Hi,
Maybe the parts, materials and engineering are better. (or just copies are not so bad if a clone)
Regards.

No, the KSN-1177 is not a copy, it´s a genuine CTS part.
The copy of that would be MPT-177, and I haven´t tried that one. There is some obvious differences between the KSN-1038 and the copy MPT-100 frame (see picture) The copy doesn´t have the same quality to the material, and the horn is a bit longer. Regards
Kim

Ive just had a further email from CPC (Farnell group - quality component supplier If I remember rightly)to say ,I must paraphrase here as Corporate lawyers forbid me to post what they actually sent!!, that
Motorola no longer manufacture Piezos but that CTS do and use the factories and plant -ex motorola. Their catalogue will be amended in the next addition (august 2006) to reflect this change but the product will
be manufactured to the same specification as the original KSN1038.I must have done some good then !!! Hah Ha seen any pigs aloft lately?
