Full Version: midrange cable..

Ciao...


i just started to collect part`s.. to a 4-way speaker(s)..
and in the past.. i have used to make my own cables..
(bass/mid/tweat.) but this time.. i don`t bother.. (yet)
there is so much to do.. so am skipping that part.

basicly i need recommendation for a cheap midrange
cable.. this typical element is going to express freq.
from approx. 700 - 3000. works at 8 ohm..
but will be delivered 4. (paper cone)..33/100).. vented magnet.))

anyone..

Blind tests : http://www.pcavtech.com/ABX/abx_wire.htm

In long discussions about speaker cables, we reached the conclusion that, untless proven otherwise, only the gauge could have an influence on the sound, and only for long cables.

hmmz..well that conclusion is
somehow.. original.

of course.. there is difference in material.
(core.. if there is solid core.. or stranded core..
de-electric.. mass.. and the way the core is shielded..)
all this makes a cable more "tuned" for certain freq. - bands..


but what this comparison shows.. and what`s a fact..
is that theres many "hoax" products around..

sorry about posting in wrong category..

I don't have facts at hand, actually, other experts provided documentation in long previous threads. But if I'm not mistaken, solid core or standed core can have an influence on the frequency range for which the cable is tuned, but usually, frequencies below 100 kHz are considered low. Between 100 kHz and 10 MHz, they are average, and above 10 MHz, high. In other words, this factor doesn't significantly influence frequencies in the audio range.

For shielding, dielectric, capacitance etc, on the other hand, the audio range is a complete mess. The formulae are simplified for frequencies below 100 Hz, or above 100 kHz. In between, the behaviour or a coaxial cable for example, is very complex.
This issue is avoided in audio using very low impedance sources (0.1 Ohm). This way, the effects of capacitance, resistance etc are rejected far beyond audibility.

There is a pecular case : high capacitance cable frying some audiophile amplifiers. It comes from a special conception of these amplifiers : with an added capacitance at the output, they fall into "positive feedback". A very high frequency (in the MHz range ?) then resonates at full power in the cable and the ampli, possibly damaging it.
This comes from a flaw in their conception : they should not allow positive feedback under any circumstances. This is done on purpose, in order to improve the sound with low capacitance cables.

This is refreshing change from many people who drone on and on about how good a particular high end speaker cable / interconnect / power cord 'sounds'. People who buy very expensive high end speaker cables are generally misinformed about the physics involved I think. It's very important to keep cables as short as possible, but other than that and the gauge as you say, they all sound much the same.

Some exotic cable designs can worsen the sound quality (and picture quality in the case of video interconnects) though perhaps not enough for the average person to ABX it. (I recall one example* from Audio Ideas Guide where a certain video cable seriously degraded the picture by filtering certain frequencies. I don't recall any specific cases regarding speaker cables though.)

* I'll track it down and post the name of the specific cable if anyone's interested.
