Question 500uF 100V Capacitor for Aurasound NS3 cube. Any other source besides Parts-Express?

I've taken the next week off to make my parents a set of the Aurasound NS3 cube speakers.

Click the image to open in full size.

I was told it needs a 500uF 100V Electrolytic Non-Polarized Capacitor which it seems like only Part-Express carries Link


How would I go about finding an alternative? Is a non-polarized capacitor necessary in this situation?

Thanks for the help,
Alfa

Are the NS3's so precious that you don't want to risk damaging them? I use them without any components, and they will distort very badly before there is enough power to damage them.

I've never built these speakers before but a friend told me he prefers how they sound with that capacitor. From some quick research it looks like the capacitor acts as a High Pass Filter which I'm guessing makes it sound less scratchy.

The capacitor will smear the sound. I personally don't like such a sound. I did not use one in mine.

I guess I should order one capacitor and test it out myself. Did you go with the 4" cube?

I used a 4x4x4 plastic cube from Home Depot. It works very well. You can try the capacitor but it doesn't serve any purpose. You also don't need 100V, as the driver could only handle a few volts anyway. It distorts already with 1W of power.

I felt like that was overkill. Did you stuff your cube? I've only seen one post doing so.

I did stuff it, but it probably makes little difference either way. The sound quality is very good at low volumes.
