In Reply to: What's the obsession with dispersion? posted by Dominic on January 26, 2007 at 17:52:47:
A relatively small reduction of bass energy radiated to the sides, above, and below, by the use of a dipole configuration, makes a modest difference in the measured bass frequency response at any seat (versus monopole bass) ... but often makes a significant improvement in the subjective sound quality of bass instruments in most rooms.If the walls, floor and ceiling of a room are stiff and are good sound reflectors, speaker dispersion can be a very important attribute, especially in smaller rooms where the speakers HAVE to be close to one or more room surfaces.
There are many speakers that measure well on-axis in an anechoic chamber, or measure well in a room using gated quasi-anechoic measurements, but they don't sound very good in real rooms. The attribute that affects their very different subjective sound quality evaluations is most likely sound dispersion (and the resulting room interactions).
