| Sloped baffle My goodness, I just glanced through the XO paper by Dr. Brüggemann. With all due respect, he is not right in many ways about how crossovers work! The technical details are far too lengthy for here, but I will point out that, in Fig. 8 on his page ... | |
| Sloped baffle Good questions.I do agree with what Bombaywalla just posted- knowledge and experience in many different areas is required. I know of no way out of that, to simplify a home-designer's life.Driver selection is by far the most important factor. If al... | |
| Sloped baffle Here are my answers to important questions posed earlier, and some clarifications.To the OP: Psag, you originally asked if a sloped baffle is important. Speaker designs that avoid this are instead using the phase shifts of their crossovers to make... | |
| Sloped baffle That's how I was presented this subject. A good link, thank you. Made me flash back to all the horrible homework involved. And then, as the math of physics became ever more advanced during grad school, one wound up using this math daily...Best,Roy | |
| Sloped baffle Ngjockey,I have looked at this site for very many years. The Soundwest site has enough errors to mislead someone relying upon it for 'basic information' and a bit of the math.Specifically:In its Section one, the author does not understand a tweete... | |
| Sloped baffle Certainly, but a lot of other problems would be fixed. | |
| Sloped baffle Sounds Real,For an eyeball estimate, the acoustic center is approximately where the voice coil former meets a cone or dome- the glue joint. But this is true only in the upper-middle range of any driver, whether tweeter, mid or woofer, where each o... | |
| Sloped baffle Hi Unsound,Thank you for your thoughts. The use of multiple subs does smooth out standing-wave issues. The math used for the theory behind that is formed from adding together the simple sinewave/wavelength equations for standing waves you have see... | |
| Sloped baffle Sounds Real- You are indeed right about 'just tilting back the front face'. That can be enough to line up the acoustic centers of woofer/mid and tweeter, so that the drivers are possibly in their best positions to combine properly at your ears, no... | |
| Sloped baffle I forgot to mention a couple of things:When a driver is being run full-range with no crossover or Zobel, its changing impedance curve has no effect on its tone balance when using solid-state amps, but only on tube amps via interaction with their m... | |
| Sloped baffle Hi to all,Bombaywalla, you ask-"So the question then becomes: Doesn't the presence of that inductive component of the driver impedance (especially in the case of the tweeter) cause a deviation from first order 6 db/octave behavior? And if so, to a... | |
| Sloped baffle Again, I look forward to people coming to understand the concepts behind my waveform illustrations. This understanding is necessary to our discussion here, because we then have agreed on the nature of these concepts at hand and also on some vocabu... | |
| Sloped baffle Hello to all,I am happy to answer some questions on design. Before that, I need everyone to truly understand the simple difference between the definitions of phase and time coherence.Please open that earlier link to my illustration, and study the ... | |
| Sloped baffle 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 lette... | |
| Sloped baffle Thank you! |
