For the last time, PLEASE: clipping does NOT blow speakers/subwoofers

As am I; few non-EE's would know the majority of that.

When you get more advanced you'll wish every signal was clipped; makes for easier calculations //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

so basically you are stating that the only way that "clipping" affects the sub is if it overpowers the sub causing it to over heat?

Yes, overheat, or exceed the limits of the suspension. Both of with are as likely as over powering the speaker with an unclipped signal. For example, if I clipped the shit out of my receiver so that it went into protection mode and sent that to my new towers, they'd laugh in its face and keep working. If I turned my Kenwood amp to moderate to high levels (unclipped), I could easily blow them.

cool and thanks... Good info if your not fvcking around with me(its about 3 15 here and brain isnt working as fast)

Lol, EE sucks. Just know that when you graduate you'll only use a small fraction of the stuff you learned in school. Alot of it is just experience (I.E. knowing the right thing to do and where/how to implement it).

I go to Texas Tech, in Lubbock. I'll be starting grad school this August.

My moofer puts out 2000 watts MAX power, though.

//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif That's a hard school. Purdue isn't being nice either, but we have a few nice looking women here, so that's all that matters. Plus, it's odd to find an athletic engineer who enjoys going 12 rounds as much as doing signal analysis. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Oh fo' real? My cuz's JLs put out like fo THOUSAND watts son, MAX too. I mean that shit be like BLAM BLAM BLAM like a ****in hurricane in the trunk, know what 'm sayin?

Probably should have put that in the first post. All that clipping is is the transformation of the signal's waveform from sinusoidal to rectangular. What that means is that if you picture the sine function from 0 to 2pi, instead of a curve, make it 2 right angled boxes with dimensions of pi x 1. The integral of the function aka, the amount under the curve is the amount of power being transferred. As you can imagine, a square wave has more power underneath the curve than a sinusoidal curve does. As a result, a clipped signal CAN send more power to a speaker than normal, but clipping is not the cause of blowing the speaker.
There are only two ways to blow a driver: mechanical failure or thermal failure. The former is due to over excursion of some form from some cause (usually improper enclosure), and the latter is usually from overpowering the speaker. If you feed a Type-R a fully clipped signal from a 300 watt amp, it will not reach thermal failure in the least. It might sound like shit, but it won't cause the speaker to fail. The driver doesn't know what it's being sent, all it does is get fed power and turn that into sound. Whether or not the signal is distorted is irrelevant.

I'm having a hard time understanding this. You are saying, comparing 2 sine waves, one that resembles a clipped signal and one that does not, that the integral of the clipped signal will have more area (or power, however you want to think of it) underneath the curve than the other? That doesn't make sense to me.

Haha, I hear you there. Half of my classes have 0 girls in them, the rest 1 or 2. I believe there were maybe 10 in the college of EE; it was pathetic. On top of that, halfof the guys are fucking WEIRD, 3/8ths are cool guys but you wouldn't wanna hang out with em outside of classes, and the last 8th are athletic/cool/all-round guys.
