The other day I replaced the foam woofer surrounds on my Urei 809's and since doing so they sound a LOT better. I have to believe the disintegrating rubber, though it looked intact, must have had thousands and tiny pinholes and thus ruined the sound.

Now that they are sounding better I think I should go for broke and replace some of the ancient parts in the crossover - yes, these are 100% original crossovers. I assume all I have to do is pull out the crossover, note the values of all the bits and pieces, purchase replacements, and replace each - one at a time.

I am quite handy with a soldering iron, so I am not worried about that.

I dont want to over simplify it nor over complicate it. My google-fu has yet to yield any useful information.

Help is much appreciated.
