    Is there any difference in capacitors that say 250VDC and 400VDC assuming they are the same uf? For example a 4.3uF 250VDC and a 4.3uF 400VDC. Thanks in advance. Off topic, but has anyone built the Pop or Grandpop speakers off of Adire's site?

    They are the same except for their power handling , 250 Volts Direct Current vs 400 volts DC. Either voltage would be fine for a crossover.

    Just to set the record straight at the expense of pedantics. Capacitors come in varying different types for different applications. How they behave in different applications will influence the performance of both the component itself and what the sound in the case of audio. I can only assume that what is asked here is possibly in relation to a crossover network. Two possible capacitor types will work here but they may very well influence the sound dramatically. A common type used usually in less expensive designs is a bi-polar electrolytic. Small, compact and non-polarity sensitive this is an inexpensive solution to crossover network design. However if space and cost is not a limiting factor, then the metalised polypropylene or polycarbonate capacitor is possibly more suitable. This type of capacitor has good dielectric properties and will maintain a constant cpacitance over a wide range of frequencies. In short, there are capacitors and there are capacitors. Choosing the right type for the application will influence the sound.
