Replacing factory crossover electrolytic capacitors to metallized polypropylene audio quality capacitors KZK K78-34
Electrolytic caps do not make great Xovers, but manufacturers use them because they are cheap. You may wonder why a company didn't spend another to use better grade capacitors, but that could end up meaning that the retail price would be 0 higher, and people are budget minded.
The KZK K78-34 capacitor is designed specifically for use in speaker crossovers and audio applications.
A set of film audio capacitors for the Yamaha NS-6490 speakers mod consists of:
KZK K78-34 250V 5% 1.5μf 2pcs;
KZK K78-34 250V 5% 4.7μf 2pcs;
Replacing stock crossover capacitors is very simple. Just unscrew and remove the speaker terminal, unsolder the factory capacitors and replace them with new ones, then stick them with hot-melt glue. Burn-in period is about 30-40 hours.
