CRX Take 3

The clipped will heat up slightly faster...I'm not argueing that. IT IS A 3 SECOND BURP.
lilmac, you need to realized that because you have put a number or two up on the TL that no one else can know something about getting loud. If you would discuss these sorts of subjects with people outside of your little clique instead of immedately assumeing they are wrong you may learn even more. I'm not saying I'm always right but you arent either.

I still tell you to put that $20 cheapo amp on your type R...honestly with no BS to try and prove a point to yourself. You wont blow it.

Last time I checked...I didnt burp with 40 watts...

where as a 4kw clipped...WILL DO DAMAGE. A 4kw square wave...will DESTROY A SPEAKER.

Go back to high school man, come back when take physics 2...then we can pwn you again.

Since you are all about siecne...do this for me..
Take two Cheap-o 5.5 drivers...send on its RMS with clean power...send one its RMS with clipped power...tell me which one gets hotter faster..

You are correct that the speaker getting the clipped signal will heat up faster! You fail to acknowledge why this is true though. A clipped signal causes a rise in heat because there is more power introduced. You will find that a pure square wave will produce about 2 times the power that it's sine counterpart produces. Take your rms power and now double it with clean rms power and see if it heats up the same as it did with the clipped rms.

Like I have said before, I have and am currently running a sub off of an amp that is clipped to audible distortion and I can run it at full tilt until the amps goes into thermal protection. The sub is NOT damaged thermally at all. Here is a picture of the voice coil:

Does that look like a voice coil that has been stressed thermally? My sub is also only rated at 500rms.

Agian. I said to try clipping...not run the amp into a square wave. Great job on missing that.

Forget it. If you are associated with that clique and have put up a decent number on the TL Physics be ****ed they are the best SPLers in the world and no one, not even someone with a degree in electrical engineering will change their minds.

If you would like to partake in this discussion in a more mature environment I invite you to SSA. I started a thread and would really like to learn where they could be comming from.

A sub can blow if its run over its thermal capacity. So if a sub is rated at say 500w thermally and you give it 1000w it may have a melt down. If you give it 500w it should be fine, thats pretty basic.

So does it really matter if that 500w is a clean signal or a clipped signal (say 400w amp clipped to a square giving a total output closer to 500w)

Does a speaker really know whether its got a sine or a square wave? All it knows about is the power its seeing right? (watts being power). If a speaker is rated for 500w and takes a 500w square wave would it heat up more due to the fact of wave being square so the speaker spending less time closer to nuetral on wave cycles? Or maybe the way the speaker reacts (moves) getting less air movement in the gap? Or maybe power is power no matter the wave form?

Rambling yes...just curious how it all works so asking some questions.

You have the right idea and it's what I've been saying all along.

Fryfucker...they dont like you at SSA either //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Either way they are a lot more mature about subjects like this. The only ones who dont like me are thoes in your clique.

I had a habbit of annoying people a lot...but who cares. It's the internet. That doesnt change facts.

Who cares?

 

[Chevyaudio 5,000+ posts]

im in an internet clique...cool.

 

[Chevyaudio 5,000+ posts]

and its funny...how the people...in the "internet clique" you speak of, are the ones actually helping the OP get loud...

 

[CBFryman2 5,000+ posts]

Yep, you seem to think so. I know people in other places that dont like you either. That doesnt make me respect you any less. But you show no respect to a good portion of people on the internet.

Listen to this guy and check out BCAE1.com...

Scroll down to the notes just before damaging tweeters.

Remember that you claim the BTL can handle upwards of 10,000w+ RMS for burps...which is what he is doing.

In either case the cone is going to be moving close to it's mechanical limits ideally so the little bit of cooling you will loose from sending it a square wave isnt a big deal.

Now for your $20 amp and type R...Claims that Type R can handle 1000w RMS. 2 $20 amp rated at 100w putting out 50 pushed into full clipping to reach that 100w is not going to harm it.

Are you so sure about this.....I had a Rockford p3001.....which is 300 watts@2 ohms and it blew and overheated the type R because the amp was clipping....so are so sure about your statement

Tommy? Tommy isnt in your clique...if he is he handles himself better.
