It's been about ten days now since I drove home with a minty, original owner, mirror-imaged pair of 4430s. Except for refoamed woofers, they are bone-stock and perfectly original. Now, being me, I must have read 25+ threads on these speakers, and no one seems to agree on the best approach to the crossovers. I have seen recommended everything from leaving them alone, to biamping or charge-coupling them.
I am probably not inclined to do anything as drastic as reconfiguring the crossovers, biamping them or constructing charge-coupled crossovers. I would, however, consider upgrading the capacitors, and so I have pored over various vendor sites for hours looking at film caps of various types, thinking about whether to mess with the stock caps and the bypass caps.
I found one thread where Zilch basically said that the only thing worth doing was to replace the bypass caps with Audiocap Thetas. I like that advice because it's so cheap and easy. But that would leave the factory Mylar main caps in place, and I know they're relatively low grade.
Does anyone have a firm opinion about replacing the caps (as compared to building new crossovers, etc.)? At this point, I'm torn between (1) doing nothing; (2) upgrading the main Mylar caps to polypropylene film caps and omitting bypass caps as superfluous; and (3) just replacing the bypass caps with Thetas.
I'm curious to hear from someone who's tried one or more of the second two options. Thanks.
