A resistor-tip: to make a good free-flowing resistor you can use lets say 4x32ohm in paralell to gert 8ohm aso. This reduces filter-resistance, the main reason for dynamic loss in passiove filters. Allmost any cheap resistor will do. Components in paralell are the worst dynanic-killers, but this trick lifts the filters power-capasity a lot.

You can do the same with caps in the lower section; only that here the values are added. Like 3x33uF makes a faster 100uf.

For top-caps I`ve used Intertechnic SCR tinfoil. Needs a few months to open up but then they dissapear totally. Not too overpriced ;)

Sleepy head, here I`m doing a tragic mixup. My long time favorit top-end cap is the Intertechnic KP-SN tinnfoil.Just invisible, perfect and just a little pricy.

But a warning; the worst polypropylene caps I`ve ever heard are called SCR; black w. orange ends. Even if someone give them to you, don't use them.

For lower freqences I`ve used the 600V version of Solen MKP. To improve the flow-capasity I run three of them in paralell, like 3x33uf to get 100uf. Combined with thick solid-core wiring this gives a horsekicking free sound.
