kenjit Its apparent that there is something you don't understand.
It has to do with the human ear/brain system.
When the ear hears a sound, a copy of the sound is made and the ear/brain system looks for other examples in near-time. If it finds an example that is delayed by about 10 mS or so, it can use that for echo-location.
That sounds a bit like a Helmholz radiator?
Let’s see here — on the dipole side we have Nola, Vandersteen, Spatial, Magnepan, Martin Logan, SoundLabs, etc, and on the other side we have…kenjit. Hmmm. I for one would love to see kenjit debate the great minds behind all these very successful speaker designs. That’d be a real hoot.
I doubt it would be a hoot.
A debate is not just about being impassioned about the topic.
One actually needs to provide some compelling argument.
Yes I do believe that the back wave needs to be in correct polarity as front. As you know, aboslute polarity is inaudible but with an open baffle, you have both waves occuring simultaneously. It is difficult to avoid the consequent cancellations unless you physically separate the two waves. That is the whole point of having a box
You kinda cannot have it both ways… where you:
- Argue that the polarity out the front is inaudible and doesn’t matter.
- Argue that the polarity out of the back is suddenly of utmost importance… and more important that the polarity out of the front.
I mean you can argue that, it is just hard to abide it as a rational argument that is anything more than “Like your opinion dude.”
