And lets not get into the high voltage VS high current long distance transmission requirements.... especially at audio frequencies.

(for instance, for 45 amps @ 20 Khz, which is the upper end of the audio spectrum, you need 4"X1/4" solid copper buss)

 

You say for long distance.. how long of a distance is that for though?

Also, won't the capacitance of such a large buss over a long distance cause the frequency to roll off? [img]smile.gif[/img]

the capacitance of that buss is measured in picofarads, and isn't a concern, and long distances for audio means generally over 20 feet.

This little factoid came from an electrical engineer... but of course the people in here "know" sooo much better.

 

Ah yes, Interesting. Didn't think it should be an issue, but there are people who tell me my 50 and 100 foot runs of 12 guage speaker cables for PA have too much capacitance and that i'm rolling off my highs.. Been told that by a few people "Higher up" than me. I guess that explains why I can't hear a differene.. because there isnt one!

So what! [img]graemlins/boring.gif[/img] [img]graemlins/boring.gif[/img] It does not mean they know about "sound" -- I've had Electrical Engineers swear up and down about how 4 gauge does not make difference in a car audio system and other such [img]graemlins/bs.gif[/img] .

Most of the time Engineering theory is based on what is "adequate" not what is better.

Professionals should stick to their professions and not expostulate with a "higher than thou" attitude on topics which may or may not be in direct accordance with their field of knowledge.

 

I didn't think anyone was disagreeing with you sass ????

I think you nailed the reasons we don't use extremly high current amplifiers....

 

so 100watts into 4 ohms is not the same as 100watts into 8 ohms
