Hello for you, what capacators is better for the tweeter super 3"
I just happened to be viewing my email when this post arrived.
Metallized polypropylene capacitors are quite satisfactory and can be purchased for as little as a few dollars apiece. Film and foil types will cost about $20 to $40 apiece if one is "into" esoteric components. Parts Express has quite an inventory. https://www.parts-express.com/cat/crossover-capacitors/292
Another type is the oil filled "bathtub" variety used as motor start/run capacitors. They usually come in an aluminum shell, can, casing. However, these are not readily found at audio dealers. They're called "bathtub" because initially they had that shape but now they come in cylindrical form also. If your preference leans in their use, they can be found at motor repair shops and heating & air conditioning parts/repair places.
Electrolytics should be avoided.
For a Super 3, typically 11 to 15 ohms, capacitor values of 2uF, 3uF and 4uF will filter at about 5000hz, 4000hz and 3000hz, respectively, at a slope of 6 dB per octave. If you are replacing such a capacitor in an existing vintage system, use the original capacitance value.
