In reply to your first statement, I mentioned to Chris at Jupiter caps, asking "it seems like at some point you just replace the whole xover". His reply was that it was not the best idea to do that, and I think his reasoning was that if your values (ie. 6.
are slightly off for a number of different parts, it can throw the crossover askew from what it originally was intended. Also, if you just replace a certain value (6.8uf) and something weird happens (besides better sound
) you know where the problem is.
As far as describing the sound: I believe the 6.8uf cap has to do with the higher frequencies (there, you see how ignorant I am of electronics) but I'm not sure if this is just for the horn tweeter or if that includes the upper mids. At any rate, the reason I looked to replace it in the first place is I was wanting more detail and air. It always sounded a bit dulled, and the reason, I believe is the parts in the crossover.
Well, I was and am very very pleased with the result, and now hear much more air and detail and strings, horns, whatever, are perceived vertically as well as more image depth and detail.
We spend a lot of money on cables and components and tweaks, trying (I believe) to get speakers to sound better when they are filtered via a crossover with lesser quality parts, and only replacing these parts give us a real window on what these speakers can do. As always YMMV, but I wholeheartedly recommend upgrading if you plan to keep your speakers. Of course you can always put the old part back and stuff it back in the cavity....
