So, I was experimenting with adding part of a cotton ball to the backside of my titaniums and find increased resolution and they now present a whole different quality to the sound. The resolution is still very clear but they just present a difference thats hard to put words to. Of course its the enjoyment of taking them apart and exploring things to make the drivers work better, i guess. Anyone else experiment with titaniums and materials used to dampen them? I also tried the foam used to dampen a set of vifa tweets but found the sound almost worse, thus the cotton ball idea. They aren't super packed within the backside of the dome itself but softly packed gently of course. Thoughts friends?

Best part, when rerunning my Advanced MCACC it needed less EQ'n to be flat, awesome! Not that it needed a bunch of correction but the objective here would be improved correction.

Adding it behind the diaphragm so it's not touching will affect any potential cavity resonance, but do nothing for any diaphragm breakup itself. If it's touching the back of the diaphragm, then it could easily be having an audible effect, any maybe not for the better (allowing for a response that's a subset of Beranek's Law)

Measurements with a calibrated mic and REW would add to seeing what you actually did. MCACC and their mic paint with a fairly broad brush.
