[QUOTE="FatDoug, post: 7949033, member: 646352"] Thanks for all of the messages guys. I was not able to find non-polar capacitors over 500 uF on the web sites for Parts Express, Fryes, Radio Shack or even Mouser Electronics - who seem to have 459,169 different capacitors! I have found many caps at over 500 uF but they all see to be polar. It is difficult to filter/search these sites for non-polar so I have called their customer support lines and the humans that I talked to could not help me find the 1500 - 2000 uF non-polar caps that I want to use as bass blockers for my 1 ohm speakers. So I have decided to serially wire three 500 uF caps and one 330 uF caps for each speaker. Per my calculations, this should block out the frequencies below 86.89 Hertz based on an impedance of 1 ohm. Of course using a single capacitor would be much more elegant, but I have been told that serially wiring four caps like this will not cause any serious loss of fidelity. Any thoughts? [/QUOTE]
