[QUOTE="Art Welter, post: 25325, member: 52"] Re: Loudspeaker Aspect Ratio's A speaker’s nominal coverage angle is generally regarded as the point where response is 6 dB down in level. One may view different coverage patterns as having different forward aspect ratios, a 30 x 30 has a higher aspect ratio than a 60 x 60, which has a higher aspect ratio than a 90 x 90, etc. To design a speaker array, knowing the coverage angles at various frequencies of the various components used, and how they will interact in the array is necessary. Whether one thinks of the polar response of a narrow dispersion speaker as having a “high aspect ratio” or “more beamy” or “higher Q” won’t change the measurement of the speaker, which is done in decibels at “X” angle and distance. Designs use measurements, regardless of what they are called. Good array design results require properly designed speakers, the language used to describe them is immaterial, though language is interesting. If the use of the term “aspect ratio” allowed you view speaker dispersion in a new light, that is good. [/QUOTE]
