Here are some rough sketches for discussion purposes. I believe that these are extremely conservative, and that your real-life performance will exceed what is suggested here. I just wanted to look at the relative performance between one L1™, and two.

The view is from behind the wall behind the L1™s.


Single L1® mono

Two L1®s twenty feet apart — dual-mono

The darker blue area represents the area where the two sound fields overlap. L1Dispersion02.jpg

This also suggests that if you were running stereo instead of dual-mono the stereo "sweet-spot" is going to be extremely wide. You don't have to be between the loudspeakers to hear both Left and Right channels.


Two L1™s with the original single L1™ field superimposed

The dark blue area shows the sound field of the original L1™. The lighter area shows the extra coverage you get by having two L1™s 20 feet apart as compared to a single L1™

The extra coverage you get with two L1™s spaced 20 feet apart, is about 10 feet on either side of the sound field of a single L1™.


The view from the other side[/b]

(Still very conservative projections)

Blue is the coverage with one L1™. Purple and Orange is the extra coverage that you might get with two L1™s 20 feet apart.

Note: The sound field will does not stop abruptly as might be interpreted by the diagrams above. It should continue, fading off gradually, well beyond what is shown here . The purpose of these diagrams is to consider the relative advantages of having two L1™s in dual mono mode compared to a single L1™.
