Horizontal Right - Tannoy Proto-J Reference Manual

In the diagrams below we have a graphical representation of the speaker systems operating at the
crossover point where both high and low frequency drivers produce the same output level. The first
one shows a pair of two-way loudspeakers lying on their side. Note that each driver is producing
sound, and because there is a physical distance separating them on the baffle, there is also a time
difference separating the drivers, and the result is what you see here. Around the crossover point,
the speaker will produce numerous lobes, producing changes in midrange sound character as you
move across the horizontal listening plane.
With the monitors laying horizontally, you will move through the largest number of variations caused by the
physical/time offsets between the drivers, if you think this is hard to look at, imagine listening to it!
Stereo occurs from left to right, so that is the listening plane in which we try to minimise the changes
in physical/time offset between the woofers and tweeters. And we have to be honest, it's not perfect,
the driver offset is still there, but by stacking the woofer and tweeter vertically on the baffle we can
give the mix engineer the widest range of movement in the horizontal plane. You can roll your chair
across the length of your mixing console and not change the relationship between the woofer and
tweeter (just don't bob your head up and down while you do it).
With the woofer and tweeter stacked vertically, you experience the least variation as you move across the
horizontal plane of the console work surface.
