does anyone sell or can i make some sort of high pass filter that goes between an amp and speaker? i am wanting to high pass my bookshelves at 80hz.

they are cambridge audio s30's. i would like to try both 6db and 12db rolloffs. i have taken the speakers apart and i'm assuming that i could probably just put a cap on the midrange's + terminal to the lead feeding into the crossover?? i metered the midrange and it is showing 3.8ohms. would i use that reading to find what cap size i need?
