Upon advice I've received, I will source/use some polypropylene capacitors for use with my latest center channel speaker project.

What I was wondering is: are poly caps "polarized" where I would have to pay attention to which side is "+" or "-"? Or do I just hook them up like I would non-polar electrolytic caps?

I think I've decided to buy them through Madisound's Solen caps listings (I'll need to get a 2.2uF from their Bennico cap listing).

Patrick,

Polypropylene capacitors are non-polarised so you don't have to worry about which way round to connect them. All capacitors used in speaker crossover networks should be non-polarised as the signal fed into them is an alternating current. One tip. Ensure the capacitors have a high enough voltage rating, especially if the speakers are high power units.

Alan, thanks for the clarification and the additional consideration for me to check when I order my caps. Posted Image
