It's kind of simple really. If the amp is running at a level where the peak light is coming on sporadically, that's not to bad, but if the amp is peaking non stop, meaning that the light is full and steadily on, you get what is a square wave in the signal which becomes much like the behavior of DC power. Speakers don't like DC power, nor do transformers or solenoids. They heat up and can burn up or short.
What I said was basically the way it was explained to me. When you are pushing an amp to the point where the the peak light is on steady and not flickering at all, you get what is, or is similar to a square wave. So far as the voice coil in the speaker, that's like putting a DC power source across it. Coils, whether speaker solenoid, or transformer, don't like DC current/power.
This pure sine wave will deliver 1.4x the average voltage and 2x the power as the unclipped sine wave.
Typo - I'm sure you meant square .
I have the brackets from the 80's and the stands, so that's not a problem.
They're an older design, but as most people know, speaker output is not all in the power rating/capability, but in the efficiency of the speakers. I've seen 4 of the 200's do an event for at least 300 - 500 people outdoors without a problem. Also, indoors at a mall for a radiothon and nowhere near the max of the speakers.
as for clipping , if your clipping the amps cause it needs to be louder then your rig is too small for the gig(i made ryhme). i repeat , if your clipping the amps because it aint loud enough you need more amps and speakers , or speakers with a higher max SPL and amps to drive them. i have seen many a small venue amps with the red clip light in constant on and the sound sucked.
Unless you've fired up your time machine and gone back to the 70's there's no reason to be running amps without clip limiters. With them you can push 3-6 db into their red before artifacts become blatantly audible.
And it was explained to you wrong.... or not completely. This is very old, very myth filled topic. The most pervasive myths contain an ounce of truth so I'll start there. Yes, a pure sine wave heavily clipped will distort to resemble a square wave. Square waves are still AC so NOT DC. This pure square wave will deliver 1.4x the average voltage and 2x the power as the unclipped sine wave. This is true and suitably scary (should be) but not what is going on with complex music driven into hard clipping. Also true, a clipped waveform will deliver more HF energy than the clean waveform, but again this is mainly a non-issue with professional loudspeakers (while probably responsible for the premature retirement of more than a few wimpy hifi tweeters).The real problem from clipping too much is not the clipping itself but the fact that you are clipping because you turned up the gain so high, so the average power you are sending to the speakers is higher by the amount you turned up the gain too high (for too long). You could clip the piss out of a 5W power amp and not hurt a fly (while you might irritate him). However speakers are capable of handling far higher short term peak power, than long term average power. This means any reasonable speaker amp combination that can take advantage os the speaker's short term peak power capability, can also break it with too much long term average power (turning it up too loud for too long).The cost to replace loudspeakers is natures way of teaching operators to be sensitive to this delicate relationship. Some are better learners than others. Many are not good listeners, this has been inspected here before. JR edit fixed mistake.
Unless you've fired up your time machine and gone back to the 70's there's no reason to be running amps without clip limiters. With them you can push 3-6 db into their red before artifacts become blatantly audible. Of course if this would overheat your drivers and fry them you shouldn't. I was once told my RCF ART310A's sounded nice and clear 1/2 mile away when doing this (and yes, that's measured - but straight up a river to a raised position so not "normal"). Stuff like that happens when you are expecting 100 or so at a park gig and 1000 or so show up .
