Interesting idea Rutger!Rutger wrote: ↑2019-08-23 20:25 Some tweeters can sound more musical when they are driven from a high impedance amplifier in active mode.
That means, putting a resistor about 3,3 ohms in series with the + connection of the tweeter can bring musical benefits.
The proof is in the listening. Ofcourse you have to compensate the gain so the tweeter sounds exactly as loud.
The reason that some loudspeakers, driven passive can sound a bit more musical in some cases is that they almost always have a resistor mounted before the tweeter.
If you like to experiment- try it. In this way, you can combine the benefits of passive and active mode.
With the resistor, the small voicecoil in the tweeter is sharing the upbuilding heat with the resistor.
I do however have problems understanding the theory behind it. Given that the tweeter plays as loud with and without the resistor, surely there can't be any difference in the heat it generates? The resistor simply lowers the level, but in addition also changes the frequency response, in relation to how the tweeter impedance curve looks. So it's certain to sound different.
My own very limited practical experience is that series resistors lowers the dynamic range of tweeters. I've always thought it was best with as little series resistance as possible. But I'm not (yet) a manufacturer of loudspeakers, so I really don't know what I'm talking about.
