What a strange situation. The aluminum faceplate is 6 mm thick and
frankly I don't see how it could happen something like that. If it were
a thin plastic, positioned in an inadequately large rebate, then yes.
You've got it wrong.
The obvious impact of ferrofluid on tweeter performance shows
the Qms parameter which is lower in value than the ones without it
and the impedance peak is flattened to some degree, more or less.
This means that the overall response around Fs is lower in magnitude.
The typical vintage Dynaudio tweeter parameters show that the total Q
depends mostly on Qms. ( Dynaudio D28/2: Qms=0,71; Qes=0,97;
Qts=0,41)
If it had obvious restrictions in FR like the massive early roll-of or any
such FR aberations, then it could have been considered less revealling,
which was never the case.
Just do an impedance sweep of the tweeter or measure its distortion first to see if that's the problem.
I've worked with that tweeter before, that filter alone will not sound right with that tweeter.
How did you come to the conclusion that this filter would be adequate?
Measurements?

already done, all right.
p.s.
someone has compared it with SB Acoustics :: SATORI TW29R-B
how perform ?
yes measurements.....of response and impedance and distortion are ok
so please suggest me which filter is adeguate in general and why mine is not
thank you
No one can make guesses about what is wrong with your filter unless you show us your measurements and tell us more about the design. The filter is far more about the design as a whole than just the tweeter in isolation. We've asked for more information a number of times and yet you do not provide us with anything.
I use these Satoris, they are awesome. Very detailed, low distortion, sweet, easy to listen a long time. HP LR2 is all you need. There is also a new high efficiency neo 96dB Satori tweeter.
thank you, do you compared them to d6600 ?I use these Satoris, they are awesome. Very detailed, low distortion, sweet, easy to listen a long time. HP LR2 is all you need. There is also a new high efficiency neo 96dB Satori tweeter.
i tried an amplifier better than mine, but not excellent and now the tw has lowered its harshness about around 80%
so what do you think about ?
so what do you think about ?
That you're amplifier is faulty but trying to attach numbers to harshness is a bit meaningless. What's your amplifier?
No, I never compared them. I only heard 6600 when it was broken.
The SB dimple is supposed to reduce distortion by steadying the center of the dome. Maybe this is why it doesn't need any EQ.
Buying a different tweeter to sort out problems elsewhere is not a good idea.
With your crossover you are bringing in the 6600 to cover basically from 10kHz to 20kHz only. There is virtually nothing up that high other than a bit of 'sparkle' or 'air' you are not going to get harshness simply from stuff in that frequency range.
With the 6600 alone and your xover you are going to hit a rather low impedance minimum of around 2 ohms at 10kHz and with the midrange driver in parallel with it things could look even worse. This is not going to be easy for your amp to drive and could be giving it problems.
When I said before that the amplifier is 'faulty' I did not really mean that it was broken, simply that it is inadequate for the job that you want it to perform.
If the amplifier does have a problem being connected to loads as low as that, then this could easily cause harshness, as the signal being fed to the midrange driver (where harshness would actually originate in your design) would also be affected by the amps inability to cope with such a low impedance.

ok, thank you for clarify.
yes my speakers have imp load very low...so onkyo that has only two transistors for each channel became faulty.....the yamaha has four transistor for each channel
