Sloped baffle

Remember, that long post is essentially a non-scientific, non-specific, biased piece of salesmanship by a guy who builds products that allegedly conform to this behavior.

I have no horse in the race. But I do like some speakers in each camp...those that conform (proven by measurements) and those that don't. I have to submit that time coherence is not the driving factor in speaker sound.

Put another way: an absolutely horrible, highly distorted speaker that is time coherent could easily be made, and great ones that are not are also made.

Again: listen with your own ears.

Kiddman, no one benefits from your insults.

If you did the math, or at least read my technical papers and relevant papers in the AES Journals, and above all hear what everyone we know hears, you would agree with me, no doubt.

You could read my letter to six moons describing the problems that measuring speakers presents, and WHY each measurement technique has particular problems. No Roy opinions there-- just scientifically-tested facts accepted by the AES.

The complete sets of measurements we post on our website for our speakers are far more detailed than any others anywhere out there.

You are wrong about being able to make a highly-distorted speaker somehow time-coherent. Its drivers themselves would not even be minimum-phase to begin with (that is, well-behaved) to be able to employ the required first-order crossover.

Best regards,
Roy

Kiddman, I'm afraid you are quite clueless & remain so. you really have no idea, do you? The more you write, the more ignorance you show in this matter...

You may feel insulted....but that does not mean I'm intending to insult you.

I can reprint papers on mixture flow in internal combuston engines, but that does not mean the heads I flow are perfect. It only means I can write theory. Self-published graphs and dyno runs done by me don't prove that they were the runs for that motor, and that the science I can read, then write papers about, ensured that my engine is the best.

I would love for your speakers to be the best, that would represent an improvement. Which upcoming show will you be playing them at? Which top electronics manufacturers are using them? Surely they must be making a splash in the industry if they are that great. I simply can't wait to hear them. Tell me where.

Bombaywalla, you've never designed anything, have you, or you would know what I said is true. A very poor speaker can be made that is still time coherent, and if you can't get that far in your brain you have little experience and education.
