Post Subject: Thinking further about the ‘compression’ of my tweeter.Posted by Romy the Cat on: 6/18/2009

I kind if cycle my attention on the notion of compression and it is not accidental. When a few years ago I used the hugely dymick NT51 tweeter in my car I experienced problem to set the right volume and I run the volume control 10  times more frequently then I would usually do. When the NT51 played low it was too loud and in soft passages it was way beyond the rood noise.

Now with Wetter Drop I have in a way the same effect. What I add a DB to my reference level then I feel that it too brought but generally I feel that there is a room for more tweeter output. I described it as luck of “compression” but not the compression in normal sense but rather tweeter non-compression – or inappropriately set relation between tweeter and MF. What I think I would need to do is not to add tweeter HF output but rather to add it’s MF output that would add the relevant amount of MF relative to HF and therefore make my HF more “compressed” in relation to the rest sound.

RAAL’s Alex advised the same but for different reasons. He feels that my tweeter shall provide more leading edge to the MF driver's impulse response. I just a bit concern that a bit overlay hygienic tone of the ribbon driver might override the tonal quality of the S2’s upon knee. Well, I will try to do go too low; let sat to 10K from 13K, and will see how it goes.

If it were not enough to add harshness then I will convert the 6E5P stage that drives the Water Drop to cathode bias and will “inject” the “harshness” by use of the cathode capacitor.
