RE: FWIW - plus calling Davey

That's why I ilked the chokes when I first read about them and tried shortly after. They did a lot of what the capless inductor was helping with (in terms of imaging).

Which reminds me, D, I keep wanting to bring back that inductor into the equation again for testing. During the early days, when I tried the chokes along with the inductor, I had some interesting imaging presentation. I did not tweak for it, as I was already going to line-level filtering. So, the inductor left the scene. Yet....

oh Daveyyyy...here is one I've been meaning to ask you about for a while:

a. Right now, the tweeter already gets the signal already filtered, in 1st order, directly from the amp
b. In the past, the "capless" tweak, required a resistor in series and the inductor in parallel to the tweeter, for a 1st order filter. The resistor burned tons of energy but it was required in series with the tweeter.
c. What happens if I keep the line-level (1st order) but in addition add the inductor + resistor BOTH in parallel with the tweeter.

In effect, I would get a 2nd order filter of some weird kind, I guess. More to the point of my question, would it be safe to move the resistor to that parallel position, in series with the inductor? At this spot, I suspect, it would still prevent a short without causing much of a drop.

This twisted mind of mine thinks that, perhaps, the combo could serve a good purpose. I don't know the proper values yet, but as long as it is relatively safe, I'd like to try it with the parts that I already have.

For inductor, I can use the .39mH/.20 DCR that I used for capless.

A resistor value of 8 ohm would - I think - make this kick in at just under 3300hz, slighty below were the first filter would already have done the job. (Oh, yes, for the first 1st order filter at line level, assume a similar slope of a 2nd or current design MMG.) So, much less energy is left.

The theoretical desirability of doing this kind of thing is probably well south of the sanity mark. I just need to know that I am not burning an amp by trying.

Yes, I know...I'll take my pills later, promise.
