LOL, yes, I must say you're correct in this statement..
Because, if you are one that dictates current practices, I
feel sorry for the rest that follows your guide lines! oh
wait, that can never happen. You just simply spit out crap
and never give any useful information that can be used in real life
applications.

You just go on, boasting your fantasy story's..

is there anything you haven't done or don't know?

I know your an old fart and most likely starting to get
senile.

According to the currently accepted rules of netquette, a post that is relevant
to several groups SHOULD be cross-posted. Most certainly not multiposted.

Explain how it is off-charter in rec.audio.tech or sci.electronics.repair where
a lot of audio is discussed daily. It was a repair question after all ! And
technical.

It's not against the law to fart in an elevator- just because you CAN do
something is it a good idea?

% out of 5 of your last crossposts have started arguments.

It appears to matter not to you. one can only assume you enjoy the
arguments.

Graham, you know I don't have anything against you. But what happens when
there is a disagreement between people in two different groups is that
persons friends join in, often they don't even understand the discussion,
they are just PO'd somebody is dissing their friiend...such arguments can't
be one by anybody, and anybody who posts more than 3 times to them has way
too much time on their hands. But Usenet is full of people with too much
time on their hands. And too little knowledge.

Actually, the easiest way to overdrive a speaker is to play it at a

level


where it produces audible distortion. But as most listeners have no

idea

what distortion sounds like...


OTOH distortion does not destroy speakers, speakers are as happy to

play

distortion as clean signal
only when you exceed the heat dissipating ability of the motor do you

burn


out a speaker

clipping does not damage speakers and distortion does not damage

speakers,


its overheating and over excursion that damages speakers
distortion is one method of achieving overheating, but you can overheat

with


a spotlessly clean signal as well




Really?, I'll make sure I don't do business with you.

Btw, distortion due to amplifier saturation, even though the amp is
far belong the rating of the speaker can and does over heat the speaker
coil and thus, can terminate the life of a speaker even rated higher
than said amp.



Ahnothetr person with minimal knowledge.

George doesn't always word things the best way, but he knows a lot.

Speakers are rated for average power, over time.

Look at the area under a square wave- it is a lot larger than the area

under

a sine wave. What that means is more power for a longer time. What is
happening is the AMOUNT of power is being increased to a speaker for a
longer TIME.

Plain and simple- that is more power. It is the amout of power over time
that kills the speaker...it can only shed heat so fast, put power in

faster

than that it will burn up.

Simple..just use a bigger amp...and drive it to peak, you can blow the
speaker quickly.

Use a smaller amp, and drive it to its full power for longer, and the
speaker will blow, assuming the amp is big enough to put out that much
average power.
Either way- it is power that is the culprit. The amount of energy being

put

into the speaker...put it in faster than the speaker can sink it, you

will

have thermal failure.

It is not DC as people who skimmed one book and didn't understand it

want to

amp

all...then

conversely

all

amps

sense


What ever you do think you know as fact, must of come at a great expense
of destroying a lot of electronics.

Again showing your gross ignorance.
As a working pro I'm sure I paid more in taxes than you earned.

Welcome to the killfiles as the only total loss I've seen today.

Dont' bother replying, but your juvenile need to will make you do it anyway.

Thank you very much, and don't worry, my kill file is full of idiots
like you.

P.S.
No one person is over anyone else. Just remember, every one
can be replaced with better than what you think you are.

out of touch with current
practice .

Voltage and resistance practice too.As well as theory.

Since you insist on groaner puns....

Ghandi of cousre, was an Indian holy man. What is not know as much is he had
to walk everywhere, consequently building up heavy callouses on his feet.

Due to poor diet, he suffered constant ill health and bad breath.

He was a super calloused fragile mystic vexed by halitosis.

I hope that settles the matter.

 

[liquidator]

In the early days of DC coupled outputs, some amps still had a degree of
internal AC coupling or bypassing in the drive circuitry.

They could indeed 'drift' DC under prolonged overdrive.

You are spot on with that condition...but I assumed that we would be talking
about "current" amps.

I wouldn't be using any of those old amps on the job.

Are you familiar with the origin of the name 'IPA' ?

Curious- India Pale? No I'd be interested in where the term came from...I
knew the gin and tonic came from having to drink quinine against malaria.

 

[liquidator]

Drive an amp hard enough and that's what you effectively get, as far as
the speaker is concerned. Try taking your head out of your arse and use
that scope.

Ignorance is bliss and you are happy the way you are.

Simply, you are just plain wrong. You seem to be interested in making
yourself look worse and worse, go on about it with somebody else please.

You've sufficiently proven it to me.

Clipping isn't DC, obvious you never studied engineering. Or physics. Or
much else, it looks like.

Bye. No more time for you. Got real things to do.

Graham, you play with toys.. you work with toys.. and as usual,
all you have left is finger pointing because you've lost what ever
you had. That is, if you had anything of value to start with other
than what you find off the backs of others.

Your knowledge of electronics is most likely gained from destroying
an untold amount of components and still to this day, you have to
scratch that bold head of yours and wonder what you did with that last
puff of smoke you allowed to escape.

You boast that your an elite in audio design, from what I've seen you
point out. A mear amateur, expert you are not!.

Answer the bloody question IDIOT !

What is a "saturated amplifier" ? You can't even use the right words.

Graham, the hole your digging is getting bigger.

IGNORANT PRICK

Me neither. I wonder if that was part of the reason for the Flame Linear
monicker, or was it just inadequate heatsinking ?

Indeed. India Pale Ale. It was indeed exported from Britain to India in the
days of the Raj and to be able to wiststand the long sea voyages had to contain
a fair percentage of alcohol to prevent it going off. The length of journey
also allowed it to mature nicely.

I think you could check "all of the above"

It was designed to be light and cheap...remember, it was a home stereo
amp...it just found favor in pro use, it was never meant to be pro...

You smuck. It's time to relinquish the community

You may want to look in the hall before sneaking back

Still saw enough of them in amp racks. Usually with a pair of Boxer fans
blowing on the heatsinks.

Studiomaster's original 800B was a modified, increased power and ruggedised
version of the PL700 with the Boxer fans built in ! And before George jumps
down my throat for copying it, it was well before my time there.

You have proved NOTHING and STILL failed to answer the question posed of you several
