Does the"quality" of jumpers affect the sound?

Davemitchell,

I have a pair of Spendor 1/2e speakers which are a three way design. The crossover points are 3kHZ and 13kHZ. How would this affect things?

Dpac996 and Bob P., thanks for setting me straight. If it is AC then polarity should not be an issue, as the current is alternating 120 times per second. How come there is so much made of absolute polarity then? It doesn't seem to make sense.

Regards,
John

How come there is so much made of absolute polarity then? It doesn't seem to make sense.

Agreed - too much is made of absolute polarity. Relatve polarity and relative phase of signals in the frequency spectrum are much more important than anything absolute.

Clio09, check your specs again. That doesn't sound possible. The 3kHz sounds right, but I can't imagine that you'd have another crossover point up higher in the treble. I'd expect to see the second crossover point between the midrange and woofer at something like 300 hz.

John,
The "AC" that comes out of your amp is not necessarily 120Hz; it's audio band signal so it ranges from 20 Hz to 20 kHz. Maybe your thinking about wall household input frequency???

anyway, Your amp, any audio amp, in general basically modulates a DC power supply with the input waveform, to produce the amplified AC output. One could easily reverse both left and right speaker cable polarity (eg swap red/blk) and not notice a bit of difference (forget about active subs and the possible issues with phase there).

(aside-If all you heard was a 120 hz signal your power supply filter caps are probably out to lunch.)
