Transmission line behavior

Jan 28, 2011 82 Replies

I use cheap figure of 8 lamp cable for speakers, but it's only a short run. For long run cable, you need to keep the cable impedance low, otherwise you can get base end cone flapping distortion. The output z of modern solid sate amps can be only a few milliohms and that's easily wrecked by hi z cables, especially on 4 ohm systems.

My ears are stuffed - around 10Khz last time I checked with an oscillator. Too much sound level while working in music in the 70's...

Regards,

Chris

In my neighborhood, base end cone flapping distortion occurs far after the neighbors have called the cops to complain about the stereo noise so large speaker cables are just a waste of money. 18" B-52 prosound monsters are WAY TOO LOUD on #18 lampcord or shielded mic cable. Even

10A of audio to them calls the cops!

Jeff Foxworthy at a frat party - "Hi again, Officer Murphy! I thought you said you didn't want to have to come back out here because of another noise complaint tonight?!"

Oddly, if I setup the 1400 watt DJ system in the backyard of some mansion for a kid's birthday party, no cops are called....probably because the neighbors are dancing in front of the big speakers....(c;]

None of the commercial manufacturers make anything much good for him and people like him. They are all trapped in making what the mediocrities = can setup. Fix him up with a real (TM) electronic engineer and deck of cards size box to work with.
