Well - my speakers caught fire.

Yikes!

 

[pravus]

you're actually sending more power on average to the speaker...

This is the part that I think a lot of people are confused and/or uneducated about. I know I was until I did a lot of reading on the subject. The problem with all the wattage ratings is that while they are accurate, they only reflect a very, very, very tiny slice of what actually happens in the real world. This very same problem is a disease in the IT world known as "benchmarks". Dynamical systems are hard to explain so I'm not sure of a good solution.

A clipped signal is not DC.

You must be joking about the "under-powering."

It would seem that my following post was missed by everyone's rush to pile on.

Yes, I know a clipped signal isn't DC. I have seen plenty of drivers burned because someone thought a brickwall limiter = speaker protection.

So, absolutely guilty of spreading inaccurate pop wisdom which I knew to be inaccurate. Also, guilty of conflating two separate issues. Sometimes you say things without thinking.

At least everyone got another chance to be rude to somebody on the internet.

I suppose that Ampeg was smart when they designed the 810 fridge. It must keep the speakers cool.

Not gonna do it, wouldn't be prudent...

The smart part was when they skipped right over neodymium and went for freon.

But I've learned so much right on the first page. I learned that cabinets have perspective when it comes to underpowering and that Genz Benz watts are 2/1 over other watts.

This is nuts. If you follow the OPs posts, he said the cones were going anyway. He already said the amp was fine. GIven the evidence on hand, it seems the cones were ready to crap out anyway. Old, dried out, sounding like they were starting to rip..... You run an amp into a cab like that at higher volumes, its gonna blow out. In this case, it went up in flames. All this talk about pedals and underpowering will never end, y'all can go back and forth for days. Literally. In the end, none of that matters here in the OPs situation IMO. I get where you guys are talking about compression and clipping, but again, I dont think that was the main problem at all. Someone earlier said it, its like he was trying to run his engine without enough oil.

Everything else is a pissing contest or he said she said.

No doubt about it but, it's very impressive to read how famous myth resist to die. And it's also impressive to read impractical attempts to explain how real world operates. IMO the DC myth is equivalent to the popular sine to square transformation where power is doubled by just same peak value. Easy to understand simplification but impractical to describe what's really going on under the hood if it comes to the point of clipped/distorted audio signals.

IMO simplifications are a good idea to provide some access to science for average skilled people. But simplifications must not be abused to try to "precisely" describe improved complexities like clipping scenarios.

Unfortunatelly every "easy to understand" simplification is a nice dunghill for myths to grow.

The founder of "DC" simplification should be put into jail,
and If I get only $0.10 for every "clipped equals square" phrase on the web I'm pretty sure I was a very rich man.

What he said is actually wrong.

And there's no such thing as "under-powering" a loudspeaker.

so you're saying that a full spectrum square wave driven by 400 watts is fine as long as the speaker is rated for 400 watts?

Is it time again where we get to post funny memes?

What is a
full spectrum square wave ???
0 dB crest ?

square wave that's 20 Hz - 20 KHz. all 400 watts of it. just asking.

Which is the one with the 40 pedals?

the one holding the guitar.

 

[ubernator]

I started with the record for the most pedals ever crammed into the original skb pedalboard. Now I rarely use even one, tuner excluded.

And that's all I have to say about that. ..

No idea what you mean, a square is either of 20Hz or 20kHz for the fundamental, spectrum depends on fundamental respectviley.
By the way 20kHz square makes no sense cause there is no guitar on this planet available doing a 20kHz fundamental
May be you worked in with simplifications too much?

edit:
guitar loudspeakers roll off around 5kHz thus no concern with 20kHz

I use one. It's a lovely TC Polytune. I also have a FDeck HPF-3 that used to be part of my setup before I moved over to a DSP power amp.

These are your clues.

Who wants a pedal that you have to shampoo after gigs?
