I have been trying a few tweaks and changes on my crossovers, one thing I have read about is using bypass caps on the main crossover caps. So, as I had to buy 50 22nf poly caps for my gainclone PSU diodes, I have loads left over so I thought I would try them on my crossovers.
I'm quite frankly stunned at the difference adding these things has made. The improvement in imaging and the extension of the soundstage is astonishing. The character of the sound has changed slightly – it’s like when I added the zobel to the gainclone –the sound is slightly smoother or maybe more refined (?) without being less detailed or smeared.
I'm sitting with my back to the speakers typing this and it's as if the entire wall behind me is reproducing the music.
I was listening to a piece of music the other day, there was a solo trumpet playing and then 2 others joined in, I could "see" where the other two musicians were sitting!!!
The main caps I'm using are SCR and Mcaps - not the best in the world but reasonably good as I understand it.
What do bypass caps on crossover caps do? Have I made some sort of mistake with the crossovers that’s corrected by the bypass caps?

AndrewT said:Hi,
it's more to do with facing away from the sound source.
We have all been listening in the wrong direction all these decades.
That's not quite what I meant - that was just an illustration of the difference.
It's the same if I turn round

bypass caps on xover caps??
hw u do that.ie have u connected 22nf cap in parallel with each xover cap or is it like u used two 22nf for each xover cap,one leg to gnd and other with xover cap.
please depict it graphically
They are connected in parallel, they just piggyback the main caps.
I have also just added some 100nf polys as an experiment but they haven't made any further difference.
I read about it on a site that reviewed various crossover caps - I'm afraid the bookmark is on a PC at work.
Oh yeah - I did listening tests with caps on one speaker at a time, then both, then took the caps off and put them on again. The difference is really very obvious.

!! That's the site I was reading
I really can't believe the difference about £1 worth of additional caps has made.

I thought the "sarcastic" and "little devil in me" smilies would show that it was a (not very humerous) joke.
Sorry, I did not intend to wind you up.
You didn't wind me up at all That's why I popped the on the end.
I just reckoned I was describing what I heard badly... again...
33nf or 33uf?
My caps are... 33uf, 4.7uf and 3.3uf - 2nd order from various bits of the12volt.com.
I haven't tried 10nf - I had the 22's left over and don't have anything else close.
The change in value is something like 0.1% so it doesn't really affect the crossover points.

I have active xovers in the car running 3 amps that cheers up 2 x 6"x9" 2 x 3 way 5", 2 x 2 way 4", 2 x 8" and 1 x 10" - I keep adjusting it all I have been known to pull over 5 or 6 times on a journey to change the xover points and levels
I would be like that with active xovers in the house too if I had them. At least with passive I can't keep messing about...
Maybe if I ever build a really special set of speakers I'll go active.

variable active xovers
did u make them yourself.if yes could u plz help me realise them bec i hadnt been able to realise varible active xovers.
if they are readymade then leave the issue.
where do u sit in the car with so many 'drivers'
