Best caps for speaker crossover?


Hi, I'm looking to upgrade my speaker with better caps in the future. I've looked into several options and I have heard that Auricaps, DynamiCaps, V-caps, and Sonic Caps Platinum are very good. Anyone made comparisons? Thanks.

Mundorf supreme /silver line. BUT, they are expensive and one MUST finalise the value required before purchasing. It's too expensive and not worth experimenting with.

Also, the differences between say Mundorf and dynamicaps and some of the (v. good) Axons, etc, ARE there... BUT: IME, the cap won't magically transform a Tangbang, excellent though it may be, into a Lowther PM4 or a Supravox 215 field coil.

I think good quality, "honest" caps make the difference; going (financially) overboard is not always necessary!
Dear Dracule 1: The Teflon caps are not for speaker XO: are too expensives and build to small values.

The standard V-caps is the one for the XO. About the internal speaker wire you can use Kimber Kable: cooper or silver, I'm using the silver type. Kimber is a hard to beat wire for this aplication.

Regards and enjoy the music.

Hi Dracule 1: Jeffreybehr ask for the caps values, this issue is very important: not only because their prices but because maybe you can't find all the values you need from the same source and you have to combine two or more caps to meet what the XO needs.

I thought that the best sounding "afordable" cap is Cresecendo from North Creek Music. Very musical and makes an instant and audible upgrade in any speaker.
