    Titanium tweeter heresy.

    I have a pair of JBL 4412A's for my office speakers which I really like. I had an Adcom GFA-555, then a pair of GFA-565's. I have been wanting to try Bryston so when a 4B came along I got it. The...

    To continue this thought, if you turned up the system gain the resulting SPL would increase more in the upper frequency range which happens to be where the CD's are.

    Hey Mitchco.

    Not that one, but thanks.

    I did find it. Might be my favorite Clapton song.

    Nice!

    The place that I am working at now has a spectrum analyzer that does an FFT to Freq domain conversion and starts at 3 Hz. :) It has me thinking about things.

    Where used list for 052Ti

    I am looking for a list of where the 052Ti tweeter was used. I have searched here but have not been able to find a list. I know the 4412a and 4408a and assume there are others.

    Thanks!!!!

    Adding a cap as you have done would work as a high pass filter which would certainly do the trick.

    Soldering would make a difference but perhaps not a discernible difference. I do intend to make more changes so the convenience of push on lugs would be appreciated. I can solder a...

    4408a placement observations

    What is/are the recommended placement(s) for 4408a's?

    Vertical rather than horizontal? Seems as though a horizontal orientation would obviate the separation inherent in the tweeters being located...

    Yes, and this is part of my inspiration for pursuing this. There must be 'as good as' if not 'better than' diaphragms that, if not presently available, can be developed.

    It looks as though the 052Ti version, D8R052Ti, is not available, only the 035Ti version.

    Other than the 4 tabs that must be clipped to fit the 052 in the 035 speaker, are they identical?

    Other than the 4408a, are there any two way JBLs that uses the 052Ti?
