@MrPeabody, I have the speakers. I've made a very strong effort to recreate the sound any way I can. I know at least one other person in this thread has as well, because I responded to them, but I believe there were others. So I'm not talking out my ass. I believe Amir heard what he heard, but its not worth turning your back on the speakers because one guy got an anomaly. I am, however, in that camp of thought that Amir acted very unprofessionally in the way he reviewed these speakers.
For the record, in case it can be argued that I'm biased in some way because I own the speakers, I'll share that I'm likely going to return them, but not because of any weird peaks or anything; I'm testing them side by with some KEFs, so I can very clearly hear the different between good separation(ELAC) and good clarity (KEF) and I've decided I likely want to invest a little more money into something that balances those really well.
In order for your take on the matter to be reasonable, you would need to have very good reason to be confident that your setup recreates all the conditions that are necessary in order for the anomaly that Amir experienced to occur. You could not possibly be certain of this. You most likely do not even know whether you wired the speaker using the same polarity that Amir used. This is inarguably part of the necessary conditions, given that Amir reported that the anomalous behavior occurred in conjunction with the woofer's coil+diaphragm assembly having been driven far to the rear and held there. I discussed this, but you ignored it and responded by effectively asserting that if it were possible under any circumstances for what Amir experienced to occur similarly with your speaker, it would have happened and you would have heard it. This is what you are asserting, in essence, and you have no justification for this. There is no possible way that you could be certain that you have duplicated all the circumstances that are required for the anomalous behavior to occur. As such, there is no possible way for you to know whether your speaker would behave the same as the one Amir measured, if he were to measure your speaker the same as he did the other one. This is simply the truth, and all you are doing is ignoring the truth, the reasons for which are of little relevance.
I did not suggest that anyone should turn their back on the speakers. In fact, my sense is presently that it is likely a very good speaker so long as it isn't expected to play very loudly.
The plausible explanation that I discussed is sufficiently plausible such that no one should dismiss it out of hand, without having a very good reason to do so. Your having not heard what Amir heard is NOT a good reason to dismiss that plausible explanation out of hand. You would need at least to offer evidence that you and the few others had all made certain to wire your speakers with the same polarity that Amir had used. And even if you did that, this would not be a good enough reason to dismiss that plausible explanation out of hand.
Have you ever closely observed the way that a simple electromechanical buzzer works? There is a circuit that when closed energizes an electromagnet that when energized moves the moveable arm on which the switch contact is mounted, thus opening the circuit, which permits the arm to move back the other direction under the force of a spring, thereby closing the circuit and energizing the magnet ... This occurs at some specific, stable periodicity. Anyone who has studied this thing and who also has good understanding of the design of conventional loudspeaker drivers will surely be compelled to wonder not why this would occur with a loudspeaker driver, but rather why it wouldn't. When the trailing end of the coil begins to leave the gap, the electromotive force rapidly declines, while at about that same amount of excursion, the restoring force provided by the suspension sharply increases. When you think about this, the question you find yourself asking isn't why this kind of buzzing would occur, but is rather why it wouldn't occur. If the coil is too short in relation to the mechanical excursion limit, the trailing end of the coil will leave the gap partly at least, and when this happens, the electrical contribution of damping will diminish, because it depends on the integral of magnetic flux in the gap and on the total length of wire in the gap. All of the ingredients for buzzer-like behavior are in place. As such, why would it be surprising for any speaker driver to behave this way if the coil/diaphragm assembly is driven to extreme excursion by a strong DC component and stimulated by frequency modulating the strong DC, with this stimulating periodicity a very close match to the natural periodicity of the buzzing? Why would it be the least bit surprising for this to occur?
