Any one ever replace caps or modify there Xovers

Might be a dumb question..but is the schematic absolutely necessary? Couldn't you just replace the old 10 uF cap with a better 10 uF cap and not have any issues?

I am with Magfan and Fishboat. It is worth trying if you really like your speakers, they'll never be Nautilus though.

In two Focal threads, member "johnsonwu" comments about the benefits of replacing original equipment x-over caps with higher quality caps… but some members said that wasn’t such a good idea … which I think "4est" is saying in his comment “they'll never be Nautilus though".

Are you guys saying higher quality caps will only change the sound of the speakers for the better?

There are many options before replacing caps. Dampening materials, coating drivers with dope to make them stifffer, using dynamat (spelling) on the driver baskets and x-overs inside the cabs, and polyfil inside the cabs. Very inexpensive and worth while. Caps are caps, each has a benefit and each has a negative. 10uf caps can get up there in price and the sizes vary significantly. Mundorf oils are cha-ching $$$$$. The benefits to me are slight when compared to other options. Finding a better componemt that mates with your speakers is much more beneficial. For instance, try a preamp that is designed as direct heated or transformer coupled. I would be that the improvement realized with this would be five to ten times better then replacing caps. You should also take a listen to different speakers. Go hear the Nola Metros for example.

Happy Listening.

Yes, by all means replace the caps, resistors or any parts that are of low quality. Would a $10,000 - $15,000 speaker use a $15 cap and other lower quality parts? Yes is the answer.

Simply read the value and replace! I did so on my Sound Lab speakers with amazing results. I purchased high quality paper in oil caps and some Ohmite planar resistors for $800 and absolutely transformed this speaker. Replaced original parts that cost $50 perhaps in total.

I have done the same with other speakers and greatly improved the sound.

Simply read the reviews on the sound quality and personality of the caps before purchasing. Purchase the ones that will get you what you want in terms of system sound.

You cannot go wrong with caps and resistors made by the top quality companies like Mundorf and others.
