Phase Cancellation and the L1
Practical Note
Only when fed the same signal, "Interference between line arrays would be more severe [than for non-line-array speakers]. In fact, the current Bose design rules for installing MA12 line arrays recommend ... a spacing between line arrays of between 6 and 15 meters! (20-50 feet)" The same applies to the L1. - Chris-at-Bose [1] (Clarifications added by the author of the quote.)
Note: During a conversation with Chris-at-Bose, he confirmed that the recommendations above are the same for the L1 Model II.
