Getting ready to order caps for my crossover networks. I noticed the 450v are quite a bit higher than the 250v caps. System is a Yamaha A/V with 70w/channel. Speakers are 2-4" 4 ohm Eminence wired in series for my center channel. Do I really need to think about the 450v? I just can't imagine that much of a voltage drop inside a crossover. Thanks in advance.
Crossover capacitors are high ripple current rated types with large conductive surfaces.
28.3V into 8 Ohms is 100W, so I wouldn’t worry about the voltage rating difference between 250V and 450V.

100v caps are sufficient in your case, they theoretically give you about 4x the needed voltage capacity and I have found that to be true in practice, I have managed to blow up 100v caps but it took using a large pro amplifier capable of generating more than 250w/ch.
WHAT 250V and 450V caps are you talking about?
Your "higher" comment makes me think unipolar electrolytics.
Can you give the full rating, including capacitance?
Sorry, JM. I meant 200v vs 400v. As far as "higher", I was referring to the price tag. I'll be using all poly-caps.
Ok, I was worried about exploding crossovers and cabinets filled with smoke (steam?) and aluminum paper bits shorting everything 😄
