Capacitor question?

Then I opened up all the speakers to find that the Dali's were the only ones using quality gauge air core inductors, and polycaps.

All the others were using either very thin gauge inductors, iron core inductors, and electrolytic caps, and some with ferrous parts in the signal path.
Of course thick gauge air core conductors and polypropylene capacitors are superior.

However, that is down to sound scientific reasons which far outweigh your perceived problem of distortion introduced by component leads and binding posts etc.
 
Thanks G.
Although this wasn't scientifically conclusive.
It may have been the Dali Drivers which made the difference, but the other speakers which I recapped and altered, all improved significantly.

You just did a guess. And there is a bunch of other options defining the outcome of some loudspeaker box.

One of my favourites in the seventies was the JBL Aquarius box. Sometime I had to repair the overloaded x-over and was very disappointed at the tiny coil with laminated iron core that had melted down. But the sound of these babies was outstanding!🙂

I hope I haven't succumbed to a bad case of belief.


It's pretty difficult to change once conditioned to think in a certain way.


The source was so authoritative and cemented over a couple of years.



I now don't feel comfortable with ferrous in the signal path.


Fortunately it's an inexpensive exercise.


Rather than improving the sound, it seems to be an exercise in making me feel better!
