No idea what those two speakers sound like. But if the choice was between Heresy IVs and Nines, it would have to be the Nines.Given the choice between The Nines and Klipschorns, I know what I'd choose.

The long-established and long-applied mathematics of Fourier analysis disagrees with you in principle.I won’t say that, but they assert they are right without saying why. It seems to me to be unlikely that a steady state set of tones can simulate the complex, almost chaotic interactions of the music in a symphony orchestra playing something like Stravinsky or Shostakovich at full throttle. Some of those tones are big in transients (percussion) and highly variable, some have more steady state tones, albeit often rapidly changing in frequency and volume level. But I guess if the expert in measurement says his few dozen steady state tones replicates that, then who am I to argue?
Broadly I agree. Multiple phemomena come under "dynamics". That always makes for interesting discussion.I think the term 'dynamics' being plural, is more likely to be an envelope term for a number of related phenomena, of which 'dynamic range is only one'. 'Fluid dynamics', for example, is a field that encompasses a number of different aspects of the behaviour and motion of fluids, such as compressibility, viscosity, differences in behaviour due to ambient pressure or temperature changes, and so-on. I don't think 'dynamics' and 'dynamic range' are interchangeable terms, one is a subset of the other.
I think the "Dynamic Range (Instantaneous Compression Test)" tests from Erin's Audio Corner (some were posted earlier) are potentially very useful in weeding out performers that don't reach a desired standard. These tests show that as audio level goes up not only does a loudspeaker "run out of steam" at some point but the frequency response changes. Sometimes a lot. It should not do this but if it does, an instrument playing loud will have a different timbre compared to when it is played softly. And, IMHO worse, an instrument playing loud will change the timbre of any accompanying instrument.
Thank you and yes, I do understand the Fourier analysis argument but, as you surmise, my supposition here is that the number of tones deployed are insufficient to provide the summation necessary to recreate a complex, rapidly changing piece of music. I recognise that they may show up potential issues during the development stages and are undoubtedly a very useful tool, but I think it is important to keep in mind that there will be a limiting point at which issues remain but won't be picked up by the test, for the reason above. We're then into the usual arguments about thresholds for negligibility. I'd liken it, perhaps, to those show dems using girl and guitar, that don't tell you whether the system will float your boat on The Bad Plus, or Prokofiev's Second Piano Concerto. And reliance on test results in lieu of listening is analogous to that, I think.The long-established and long-applied mathematics of Fourier analysis disagrees with you in principle.
An audio signal (one channel) is a well-behaved function of amplitude (usually voltage) versus time. Fourier analysis shows that over any period you want to choose such a function (audio signal) can be re-created by summing steady state sine waves.
If the argument here is that Joseph Fourier (and those who developed his fundamental work on functions into Fourier Analysis) and Wolfgang Klippel have got it wrong it would be interesting to hear exactly how. I assume you are objecting on the basis of the limited number of tones used in the Klippel test. But actually the Klippel test does not have to re-create an arbitrary piece of music - it just has to be enough to reveal problems in a system that may need to be addressed - if they are significant enough.
The multi-tone test is a big step forward in revealing (undesirable to me - I won't speak for others) non-linear behaviour (including poor dynamics) in systems like loudspeakers, DACs and amplifiers. The idea may have emerged in a 1970s paper I have from BBC Research on audio systems. Nowadays we have the means to easily generate the test signal so the test is practical and IMHO useful.
Let's not throw the baby out with the bath water. Modern measurements including multi-tone distortion tests are excellent at showing up defects from a conventional standard of perfection. IMHO the chase for needless perfection should be avoided, but when I understand where to draw the line, to me they are excellent at showing up kit I would not spend my time on auditioning. Yes, the tests might still be improved, and yes, if someone prefers equipment that doesn't meet the conventional standard that's OK - and I do have issues with some loudspeaker evaluations. But some of us do like the conventional ideas of low distortion in audio systems. The test that doesn't seem to please someone might please others.
you are wasting your time with this guy ,how can someone be taken serious when he never listen this speakers but can say how good or bad they are? its ridiculous.What is the word ‘finally’ for in the thread title?
And what is the word ‘some’ for in the thread title?
I think you'd like the FinkTeam speakers Joe, not least because mine are named after Ensign Kim, and they have a bigger model, the Borg (which, sadly, is not cube shaped).Steve,
I thought you had made up a company name for the yuk-yuks. Ha, it's real.
Joe, owner of back-loaded horny speakers from TeamGuy or maybe GuyTeam. I'm not sure which sounds better.
Sure, but discussion may be in danger of getting into the territory of "the perfect is the enemy of the good". Yes - a non-linearity needs to be exercised by the test signal to show up. And I could probably design a non-linearity that would be difficult to find. But it would be a very un-natural non-linearity.Thank you and yes, I do understand the Fourier analysis argument but, as you surmise, my supposition here is that the number of tones deployed are insufficient to provide the summation necessary to recreate a complex, rapidly changing piece of music.

Modern multi-tone tests like the ones we are discussing for sure pick up natural non-linearities much better than older tests. I refuse to be one of the ultra-objectivists who goes down the rabbit hole chasing a DAC with a 123 dB SNR because its better than one measuring at 122 dB. So, I will happily take the information from a multi-tone test and make use of it in selecting gear to audition and be confident that the test may not be perfect but will be much better at weeding out poor performers than previously. To me, this is not about a perfect destination. It's about a good step on an continuing journey.

My post wasn't an attempt to stifle discussion. But only that discussion from totally diametrically opposed positions is fruitless and leads to nothing positive. If people disagree with nuance, then fine go ahead and have a debate about it. But there's zero to be gained by an apple lover telling an orange lover that they're wrong to dislike apples and like oranges (or a motorbike lover telling a car lover cars are crap, and all such totally pointless conversations). That's just expressing an opinion because you like the sound of your own voice (yes I'm fully aware that I've done this myself, and I'm aiming to try my best to stop), it's not driven by anything more than ego (yes I am also throwing that accusation at myself).Fair enough in its own terms, but if a thread is started which takes a position on something, I feel entirely justified in engaging with it. And if I disagree, it’s entirely right that I get to say so. Otherwise, if your position is right, the only acceptable responses to an OP would be those that say ‘yes, that’s right’. Can’t see this forum lasting long if that happens.
And you'd be entirely correct of course. I mean we only have to hear people say things like " my headphones go from 20hz to 20khz, they're better than yours because they only go down to 30hz" or similar comments that are clearly founded on a misunderstanding of measurements, or at least are being mislead by what they've been told is important when it comes to measurements. Your comments regarding speaker dynamics are completely on point, in the sense that at least you're thinking about "what are dynamics and how best can we determine them?". A lot of people (I'd go as far as to say the vast majority, if we're including the general population), just look at the frequency response and that's their limit as far as their understanding of measurements is concerned, and as you've stated they are very likely making bad choices because of their use of measurements.Thank you, and I think we're in danger of being in violent agreement!
I suppose I might summarise my position as recognising that I don't know enough about measurements to be confident that I could or would interpret them appropriately, and I have my suspicions that some that believe they do are a little misguided. This leads to the risk that some people who set great store by such things, dismiss, or embrace, products on the basis of information they haven't fully assimilated. That's their lookout and their choice, and is up to them of course, and it's none of my business if they do, unless or until they urge others to follow their lead in which case, I think that gives me licence to have my say.
