it's all the same in the end, as far as the drivers concerned.

You can keep on arguing that its the extra power that distroyes the speaker and not the clipping, but I am sure you can agree that your not getting that extra power without the amp clipping. They go hand in hand in this scenario. This is the reason why I point my figure to the clipping.

Of course I never said cliping will always damage a speaker just like overpowering wont always damage speakers.

The key is when "theboy" mentions this: underpowering(distortion)?????

I agree that only underpowering wont damage the speaker, but when adding distortion in the form of the amp cliping then that leaves the door open to my scenario where the amp can now produce more then its rated power, lower the heat dissapating capabilities of the speaker and potentially damage it.

ok let's try it this way...

you have a driver that can safely handel 500w RMS

Take an amp capable of putting out 100W RMS, and for the sake of argument, I'll use your stats that an amp can put out 50% more power when fully clipped...

are you saying that the 500w driver will suffer any damage from an amp putting out a 150W clipped signal???

Mechanical failure= clipping signal and drive the voice coil beyond its limit

Thermal failure= clipping signal and drive the voicecoil melt down, clipping causes the air not coolinn voice coil.


remember: any amp can blow any speaker, set right the gain, avoid any clipping.

correct me if ^^ is wrong.

really?

mechanical failure is merely overpowering the driver to extend past it's limits, and thermal failure is too much power, and the driver's inability to disipate the heat built up.

^^^ how do you arrive at that conclusion?

This is freakin silly....
AMP 200 watts
Subwoofer 250watts
I am sure you can come up with many other types of scenario similar to mine.

In any case, it has become quite obvious to me, Mark, that you can never be wrong. I know this now especially after correcting you in the jackhammer thread yet somehow, according to you, you are stilll right. It is obviously futile to continu this here. I have made my point, others can make of it what they will.

correction on my other post, mechanical failure = Speakers can also be damaged mechanically by driving it beyond what the suspension can handle. Mechanical damage is generally caused by driving the speaker with too much power but it can also be done when a speaker is in a ported enclosure and is driven with frequencies below the port tuning frequency. <bcae1.com

remember, ur volume control adjust ur speakrs life

you haven't offered any information other than running around in circles why you are right. if you want keep telling me you're right, then go ahead... it still doesn't change anything...

how is this 'silly'? I gave an example of an amp putting out a highly clipped signal, distorted and all, and yet it won't have any effect on the driver, as far as damage... how does that not make sense to you?

If underpowering can never damage a speaker, how does one explain people blowing up 40-60watt RMS speakers off of the 14-17watts RMS you get out of a deck?

Well I have a good website for you
