Highest output resolving tweeter capacitor

Rewards can be gurenteed , How are u going run it...is it A hand built crossover..do you have the ground coil..1st order yeilds most results with expensive caps...tops is audyn pure copper....and not really needed in 2nd and 3rd order arrangements.
 
I would say that any non-magnetic lead PP film foil capacitor would sound better compared to the other cheaper metalized foil types. Audyn caps are good, but so are many of the other similarly built caps. Personally I like PIO in series with a high efficiency tweeter, but its more of a matter of the combination of parts that contribute to the outcome as to how well they complement each other, so there isn't just one "best" capacitor for tweeter crossover duty.
 
Try and get some Mica film and polystyrene film cap .
They r as exotic as unicorn nowdays. But let me tell you this go get some real cheep capacitor and compare with some audiophile cap. First check the cap value is correct with a cheap multimeter with capacitance measuring capability n just test it using only tweeter with all the different the cap . Maybe I am tone deaf but I cannot even tell the difference between them....of course I used new reasonable quality caps . Lastly U can use them in parallel to reach whatever value u need..and enjoy the incredible improvement in sound as describe by some .
