Resistor types?

[goraman]

Do resisters make a huge difference in a speaker xover for example'

Some like Mills some like Mundorf,I have only ever had sand cast so I don't really know if it makes any difference?

[Z-A]

Getting into this stuff aren't you?
Basic answer is yes, anything in the signal path will affect the sonic output, the types you mention are all good, til you use the Duelund cast, which seem to have no audible effect on the signal. They are £££, but worth it.

Once again it depends on what it's doing. If it's shunting to ground then it won't have as much effect as a resistor that carries signal to a driver.

In the case of some resistor feeding a tweeter look for low inductance (though you have to be careful as this might have been taken into account on the original design)

Further to above, I would not describe the difference as 'huge' though, it is more of a final clean up after high quality caps.

Maybe the Deulunds sound so good because they are made out of pencils? Maybe they just 'draw' the music out.... ;-)

I got Mills resisters ordered today'
6 in total and yes I got some for shunting the tweeters,but I couldn't get the same 50 ohm so I got a couple 47 ohm instead.
I wonder if it will make much difference.

I will never spend $25.00 each for the Duelund resisters $150.00 plus tax and shipping! for 6 resisters!
And they look like doobies,badly rolled doobies with 2 built in wire roach clips.
LOOK! IT EVEN GETS CRAZIER! http://www.partsconnexion.com/resist...lund_cast.html OVER $300.00+ tax and shipping!!!

50 ohm to 47 ohm, let me think


I'd be amazed if you could tell the difference, it'll be less than half a decibel & at a frequency where human ears are not so sensitive

So not really - no.

Some very fine and expensive passive speakers in past decades were wired with standard resistors and fed from the amp with garden grade mains cable at a notable audio show - I'm thinking of the Quad 57's, which really don't need all this bullsh*t to sound great

You asked wether resistors made a huge difference, perhaps you meant to ask 'what should I buy?'. In your case I'm sure mills are fine. It's all relevant to where you use them of course. What they remind you of when you see a photo of one is a poor indicator of how they will sound in a crossover..
Ps, things have moved on a bit since the 57's.
