Best caps for speaker crossover?

Rauliguegas, the V-caps now come in two flavors, Teflon and Oil-film(?). Which would be better for speaker applications? By the way, I've always thought about using Alpha-Core inductors. Any thoughts on what type of wire to use inside the speaker and speaker terminals?

Thanks guys for all your input. I figured the V-caps would come out on top for most applications. Too bad they cost so much. I'm not willing to put in more than $300 tops for caps. I'm going to have to take a look at the X-over in the future and figure out how much it's going to cost me.

What are the cap values?

Jeffreybehr, I have not had a chance to look at the caps yet. I will post the values in the future.

If you can afford Jensens, I can't imagine it getting much better. As has been stated already, caps bring their own sonic signature, but who could argue against a cap that sounds lush, dynamic, detailed and as musical as the Jensens?

Has anyone bypassed the motor run caps with the relatively cheap russian Teflon .1uf or.057uf caps? If so what were the results? In a speaker XO application primarily,although feel free to chime in with your power supply results.
