I'd say that plus having the speaker cabinets far enough away from the listener so they are no longer perceived as individual sources.I think it down to the cabinet they are in rather than the speakers themselves..
It's a silly name someone came up with, probably for advertising.What is a holographic stereo speaker?
No, it's a real thing. Actually, it's a mind game that mimics the real thing. And, as above, it has nothing to do with the speakers. The physics and psychology are very well known, and documented in both peer-reviewed scientific journals and patents.They don't, it's just a stupid advertising gimmick.
What is a holographic stereo speaker? Have you encountered speakers that even though they produce audio, they create a visual hologram in mid air?
It doesn't show visual hologram in mid air but you can feel depth(in addition to width) of instruments and their placement on y and z axises. Normal stereo is spread on x axis.What do you understand is the difference between normal stereo and 'holographic stereo'?
While he got the name it was used back farther than that. Don't remember if it was Greeks or Romans that used many different size clay jars placed in certain spots in their ampitheaters The jars made speech so it was able to be understood in the whole area.The round hole in a guitar is a version of a "Helmholtz resonator", named after a *really* smart guy in the 1850's
That's pretty much the "expanded stereo" effect that stretches the sound field beyond the width of the stereo speakers.A sound reproducing system having right and left speakers which transmit right and left stereo sounds, respectively. The right signal, in addition to driving the right speaker, is inverted and delayed to produce a compensating signal which is transmitted to the left speaker to produce a delayed...patents.google.com
eg. Dolby Pro Logic encoding, for the commonest one.Separate from this is "matrix audio",
