Great stuff! I have found similar improvements with those types of speaker mods. Very, very rewarding for the money spent.

Congratulations.

Glad to hear you're happy with your speakers Matthieu, you've inspired me to have a play with mine!

I want to replace a 25uF cap in my crossover, but I can only find 22uF, could I use this? If so what would the difference would it make to the sound? Would it restrict bass?

Sorry for being a little o/t.

Cheers, Lee.

Don't bother and take it as a chance to mix caps!
My advice:
one ClarityCap SA 22µF and one Mundorf Supreme in // 2.7µF or 3.3µF if needed: that's a very rewarding match most of french DIY's folk said.

edit: I've had constant music today, away or sittin'n enjoy: woww! So much space! Like I'm in in a bigger room! And much more details flow with ease! This is a must be done... more than a clock in a CDP!

Ah, I didn't think of doing it with one good cap and then one uber cap. I was looking at using BG AC's 10uF + 15uF. I wonder which will be the best combination. Also, fitting them in may be a problem.

Just thought I'd attach a pic if anyone's interested. No more o/t I promise.

Regards, Lee.

Lee,

My advice is:

1) Cut your nails.
2) Parallel some caps as per Matthieu's advice.

What is that large cap doing in your speakers?

Hi there,
wanna know if I go for a 5W resistor to replace the 5W instead of a 10? Any improvment in using a 10W instead of OEM 5?

Thanks,
Matthieu

Theoretically better temperature stability (less ppm) for given dissipation. I doubt you will hear an improvement if not of better construction and material quality too (Mills etc). It will certainly not hurt.

1R65 instead of 1R5, too much excited highs, I've tried 1R8 wich killed the highs... 2x 3R3//3R3 are in. A bit less green stuff back panel and damping feet removed and cabinet held on foot with Blu-Tack instead of these round small pieces of rubber : whoowwww !
Bass are strong and well hold, medium is very detailled now!

At a glance:
Filter upgrade: better dynamics, better matter and better details in half top,
damping upgrade : better control of half bottom,
Blu-Tack and OEM rubber feet removed : strong bass

Blu Tack is good
