How Loud is it if you put the L1s in front of you

The L1 systems offer extremely wide horizontal coverage (approximately 180 degrees), however, we rarely consider loudness behind them.

Major Concepts

How Directional are the L1s

Up to about 1000 Hz, the L1s are almost omnidirectional. They become increasingly directional, with more sound in the 180-degree range facing forward as the frequencies rise beyond 1000 Hz.

Most of what we hear in the human vocal range and instruments is below 2000 Hz. See the colored chart below for more details.

If you find the L1s too loud when placed behind you, putting them beside or ahead of you will make very little difference for frequencies up to 1000 Hz.
