ALK x-over--- inductors

[Shock-Late]

Al, two more questions about your x-overs )

1) I don't find 0.20 and o.30 mHy litz wire inductors here in Belgium; only 0.22 and 0.33.... should I cut some wire off them to make them correct values or may I keep them as they are?

2)could I use some QED Qudos speaker cable for the x-over wiring?

thanks! ;o)

Frans,

Do NOT use the inductor values you mentioned without removing turns. The squawker / tweeter crossover will be lower and the impedance will no longer be 8 Ohms if you do. You can remove wire, but you must remove the EXACT amout to get down to .2 and .3 mHy. To do that you will need precision instruments. If you just pull some off you chances of getting to the correct values is very slim. Inother words, you best look for the right values someplace!

As to the wire, use simple AWG 14 stranded wire if you need to buy it. It is NOT critical at all. USe whatever you have on hand.

Okay...

the guy who sells the inductor has the needed precision instruments you mentioned... he use to build x-overs and speakers himself (he owns a terrific black pair of JMLab Utopia copies he made himself). He'll cut the wire off the inductors for me, he told me.

I have some unused QED speaker cable at home; I will use it then.

thanks ;o)

Frans,

OK! Try to get him to shoot for +-1% accuracy. That's what Solen specks them at. My instruments pretty much agree.
