Note: I apologize to the nine AKer's who had already responded to my initial poll on this topic before I deleted it (all had voted YES). I had intended to make the poll anonymous, but failed to do so. This version corrects that mistake and simplifies the responses.


The question of whether or not clipping damages speakers always leads to a lot of debate and disagreement. Given current thinking by those learned in the variables and the associated science, I'm guessing that beliefs on this topic may be changing. So, I thought I would set up a simple poll to see if this is the case. Yes, I know that this kind of non-random poll is not reliable...but it will still be interesting.

The question is: Does clipping cause speaker damage?

Definition of Clipping: The situation in which an amplifier is pushed to create a signal with more amplitude than the power supply can produce. The portion of the signal which is beyond the capability of the amplifier is "cut off" (clipped). Subsequent failures of the amplifier, such as oscillation - while they may be triggered by excessive clipping - are outside the scope of this poll.

An additional note of clarification; the intent of the question is to determine beliefs regarding whether or not clipping is a primary cause of speaker damage. There may, of course, be other ways in which speaker damage occurs. And, the question is NOT "does clipping always damage speakers". In other words, one does not have to believe that clipping causes damage in all cases to believe that it creates a significant risk of damage occurring, or that it is a common/frequent cause of damage.

Choose the answer that best describes your beliefs on the subject. The four possible responses are:
  1. Yes.
  2. No, but I would have said yes if asked 1 or 2 years ago
  3. No.
  4. Undecided.


The poll will be open until the end of January, 2015. I know it may be difficult, but I sure would appreciate it if respondents can abstain from debating the question here...there are plenty of other threads where that can be done!

My amp only puts out 5.8 watts per channel at 8 Ohms. What's the chance it's gonna damage anything, with any signal, clipped or not?

Depends on your speakers? But in this case a general "no" is probably correct.


If one has a 50w amp and speakers rated for 70w, then yes. I voted yes because I've personally seen it happen at many parties.
 
May I humbly suggest you really clearly state that this thread is about clipping damaging speakers, and NOT oscillations and other bad behaviour that results from wonky amplifiers when they clip. Can we, for once, assume we're talking about quality amplifiers here that clip 'cleanly'? Thus, truly limiting the discusion to clipping causing the damage, not amplifer faults. Perhaps use a bold large font when saying clipping.

Just my thoughts.
 
If the amp clips cleanly and the output is less than the speaker's rating, if will just sounf like cr@p. If the amp misbehaves, high DC, etc, that's a horse of another color.
 
The term "clipping" means that the output of output devices has surpassed the current capabilities of its power supply. In SS amps, that would mean that the output sine wave has had the top of the wave chopped off....and that is DC voltage at that part of the wave. That means that for those micro seconds, the speakers are receiving current, but simply standing still, because all they are seeing is DC (direct current). This causes the voice coils to heat up and if the condition lasts long enough, warp the voice coil, causing it to scrape against the pole piece, which eventually will lead to the speaker's destruction. I have seen speakers that I have worked on that had a fire in the voice coil of the speaker.

So I have a little button on my amp that states (DC / Low cut 2Hz).

Its for the input (TT rumble?) I presume, but I'm not certain.

So NeonDriver and WaynerN, I guess you just can't help yourselves and feel compelled to not respect the wishes expressed by the OP? You do realize that when you opine aloud your beliefs, you are just baiting others to join the fun, right?

Really, it's simple, does clipping damage speakers, yes, no, or otherwise.

Exactly! :thmbsp:

I've experienced those results personally. Not pretty. And not a good thing to walk into your stereo listening room and smell fried electronics, and know that someone was playing your stereo. Without your knowledge. And burn out a dome mid in your AR90's! It looked like an eyeball that had popped out of it's socket!!! Yuck. :sigh:

Unless you're talking about woofer damage, it's not DC that does the damage. The crossover caps will protect everything except the woofers from DC. It's the high frequency harmonics that do the damage (if they exceed the tweeter, or mid range driver's power rating). A speaker might be rated for 100W, but the tweeter might only be good for 5-10W. You can do just as much damage by playing undistorted high frequency sine waves.
 
Maybe catagory

This needs added and expresses my opinion. It depends on how much clipping (how far over where it starts to clip), how long and what the amp and speaker ratings are.
 
Insufficient parameters given for an educated answer.... We need a defined situation to decide the correct answer.
