A dipole speaker enclosure in its simplest form is constructed by mounting a loudspeaker driver on a flat panel. The panel may be folded to conserve space. The panel may be folded to conserve space. The term dipole derives from the fact that the polar response consists of two lobes , with equal radiation forwards and backwards, and none ...
A stereo dipole is a sound source in an Ambiophonic system, made by two closely spaced loudspeakers that ideally span 10 to 30 degrees. Thanks to the cross-talk cancellation method, a stereo dipole can render an acoustic stereo image nearly 180 degrees wide (single stereo dipole) or 360 degrees (dual or double stereo dipole).
For example, a typical electrodynamic speaker driver can have a moving mass of tens or hundreds of grams, whereas an electrostatic membrane only has a mass of a few milligrams, several times less than the very lightest of electrodynamic tweeters. The concomitant air load, often insignificant in dynamic speakers, is usually tens of grams because ...
Furthermore, the constant of proportionality is the same irrespective of the nature of the antenna, and so must be the same for all antennas. Analysis of a particular antenna (such as a Hertzian dipole), shows that this constant is , where is the free-space wavelength. Hence, for any antenna the gain and the effective aperture are related by
Magnepan has used several different technologies in constructing their magnetostatic speakers.All Magnepan speakers are based on flexible ferrite magnet strips (like refrigerator magnets), 0.060" (1.5 mm) thick, typically cut to either 1/4" (6 mm) wide (mid-bass) or 1/8" (3 mm) wide (tweeters) and more or less the length of the speaker.
Popular belief: Kit-Kat Reality: Kit Kat Yes, it’s true: A hyphen doesn’t separate the “kit” from “kat.” The brand even addressed the Mandela effect in a tweet from 2016, saying “the ...
By truncating this expansion (for example, retaining only the dipole terms, or only the dipole and quadrupole terms, or etc.), the results of the previous section are regained. In particular, truncating the expansion at the dipole term, the result is indistinguishable from the polarization density generated by a uniform dipole moment confined ...
Here are some Mandela effect examples that have confused me over the years — and many others too. Grab your friends and see which false memories you may share. 1.
