triangle properties
The ideal speakers are wider and longer
than the venue…but only by a little
There’s no point in paying extra so that people outside the
venue can hear the show, but you need to be sure that everybody
inside can hear.
Too wide and short Too narrow and long Just wide and long enough

Use what you know about your venue to quickly reduce your
speaker options to just two. (Cross out ones you’re rejecting.)
The venue length is 75m.
Spread Angle 60m 100m 200m
60º $1500 $2000 $3000
90º $2500 $3000 $4000
Both these speakers are going to reach the back.
Q:
Is this for real? Are speakers really sold by angles?
A:Yup. Common sizes are 60º, 90º, and 120º. Bass
speakers tend to be broad, and tweeters (for higher
frequencies) are narrower, but all vary. Apparently for
perfect sound quality you need to sit so that you and
your two stereo speakers (left and right) make a perfect
equilateral triangle. But that’s only for really hardcore
music geeks.
Q:
And don’t we need more than one speaker?
A:What you’re really ordering is a speaker system, which
would probably have more than one unit.
