Feedback (high-pitched feedback) is typically at frequencies above 2000 Hz, so there may be some benefit to position the L1s outside the polar pattern of microphones if you have exhausted other approaches for dealing with feedback. You can do this by putting the L1s in line with or ahead of the microphones.

The average difference measuring in front of an L1 and directly behind it (180 degrees off-axis) is +3 dB SPL dBA and dBC. | |||
The average difference measuring in front of an L1 and beside it (90 degrees off-axis) is +3 dB SPL dBA and dBC. | |||
Conditions: | |||
*L1 Pro16 | |||
*In a free field (outside, no walls) | |||
*Using white noise | |||
*Testing with a Sound Pressure Level (SPL) meter | |||
*A-weighted and C-weighted (dBA and dBC) | |||
