Generated Square Wave vs Forced Square Wave

[shizzzon 461]

I like to keep tweakin test tones and have a question about something-

When analyzing the test tones i generate, using a pure sine wave, i get a 30db amplitude reading.

Now, if i generate a square wave, i get 32db amplitude.

So... in theory, the generated square wave will produce higher levels of spl at a lower power level...

But.. does a generated square wave have the same effect as a forced square wave?

meaning... will the sub(s) heat up quicker even with a non-clipped signal compared to a generated sine wave?

I'm assuming a generated square wave will clip sooner than a sine wave due to the increase in amplitude...

I'm speculating on whether it would be worth my time testing square vs sine on the mic to see if one can meter a higher number.

The other fear i have is will a clipped generated square wave have the potential to cause sub failure many times quicker than a clipped generated sine wave?

Not sure I understand exactly what you are asking.

Perhaps I can state something that will clear it up for you. Average power on a pure sine wave is .707 * peak (ie RMS), obviously on a square wave this isn't the case as your meter showed you.

A signal is a signal. the sub won't know the difference, other than the increased amplitude.

For a sine wave, RMS Voltage is;

Vrms = 0.707*Vpeak

For a square wave, RMS Voltage is;

Vrms = Vpeak

And Average Power (also known as RMS power, even though that term technically doesn't exist)

Pavg = (Vrms)^2/R

As you can see, for a square wave RMS voltage is equal to peak voltage, so compared to a sine wave average power will double.
