Dear friends: This cap tests evaluation for my speaker crossover is really complicated due that Vishay, Wima, Kemet and Epcos has each one " hundreds " of models for multiple/several applications and inside each application model exist " dozens " of options to as a choice.
Of course no one of that applications says: speaker crossovers, so I'm buying diferent models of the same values and testing it. Not really an easy task but quite learning one.
Now, things are that sometime inside same manufacturer models and sometimes caps from diferent manufacturers caps performs almost at the same quality performance levels and all signatureless.
The issue down there is: which is the best choice?, very hard to say and what I'm doing is to have in different days using same recordings ( analog/digital. ) listen for a while at high SPL ( always same SPL. ) and I decided that the choice will be and is the cap that after eachh listen session let my ears/brain more " calm " and with the less/lower sensation of that time listening to high SPL's.
I decided that because I had not ( yet ) other better alternative. Advises are welcomed.
All those made it that today my crossovers are a blend of manufacturer caps where no one of them works as a tone control. That's why the blend: colorless.
