One more question: shall I use solid silver (40 years old) wire in teflon insulation for the tweeter? I would connect the tweeter part directly with the crossover.
Thanks,

I really don't know - give it a try, and if you like it, keep it!

A quick suggestion... seeing as you have the backs off the speakers why not earth the driver? I've been thinking of doing this myself but it's only something I've heard about.. some say it has sonic improvements and some don't.

I'd stick with copper mate...

What do you mean by earthing the drivers?
I've never seen and heard about it. Could you maybe describe it in more details?

Thanks for the suggestion. I will stick to copper with the HF unit as well.
I know that for the bass thick copper wire is suggested, but should it be solid core, multistrand or litze? What diameter (solid, multistrand or litze) is suggested for the HF unit?

For the bass finally I did not order the AN-D but I bought UPOCC Neotech 1,2mm diameter solid core copper wire. I got today the 1,5 and 3,3uF Bennic capacitors. They are much smaller than the ClarityCaps so the fit nicely in the original crossover. This way all capacitors are replaced in the crossover but the resistors are the old ones.
I hope this upgrade will improve the sound. I still have to resolder all solder points and to clean all connections (especially in the rotary switches).

mine is the same thickness for the HF and sounds superb.

Earthing speakers is very much something that is a 'try it and see'. It's (apparently) best if the whole system is earthed via a 'star' terminal and that goes straight to a copper rod buried in the ground. Russ Andrews sell the terminals but I don't like having my leg lifted as the prices there are still back in 2006... stooopidly expensive.

Here is a photo of the upgraded crossover :-)

Combination of ClarityCaps and Bennics. If I would only use Bennic capacitors the whole thing would fit more nicely but I ordered the ClarityCaps before I realized that I can buy Bennic caps locally.
I am not sure which one is better: ClarityCap or Bennic.
This is only one crossover, I still have to do the other and I have to install the new wire as well.

Hi László,

Any chance of uploading that image through Photobucket or Imageshack, where it can then be viewed instantly and resized properly for message boards?

Marco.

Sure, here it is. Thanks for the suggestion, I've never used imageshack before and was wondering how could I attach a larger photo :-)
