[JimPA]

The more expensivegrs-phenolic-ring-tweeter-replacement-for-ar-4x-cts-marantz-and-more-8-ohm--270-252
version has a lower Fs.
This can be crossed over a little lower then the rt-6-2-phenolic-ring-tweeter-with-grill-8-ohm--279-462.

Hi Jim! Wow...first of all, let me say what a sweet doggy I can see in your picture!
I love her.
Regarding to our thread, thank to your precious help I understood that there're two versions of these tweeters (at least I think so): the best one can reach about 20.000hZ...and perhaps the cheap one can reach a frequency of 15.000 hZ.
Do you agree, Jim?
Thank you very much and congratulations for the doggy!
Regards from Italy

The rt-6-2-phenolic-ring-tweeter-with-grill-8-ohm--279-462 less expensive tweeter seems to go flat to 20,000 hz.
Unfortunately the response graph isn't included.

The more expensive grs-phenolic-ring-tweeter-replacement-for-ar-4x-cts-marantz-and-more-8-ohm--270-252 is only flat to 15,000 hz.
