Ideally we wish to keep the unavoidable contribution of the room sound over the direct sound below the

threshold where the room influenced sound overwhelms the direct sound.

The modular nature of the LS-77 OptiArray® system allows AMR’s setup to be scaled to almost any size

listening room. As the numbers of speaker pairs are increased in the Opti-Array configuration, the power

handling and SPL capability increase ever more dramatically over a single pair of LS-77s.

AMR recommends the following OptiArray Setups:

Room Size <35m

25m

–70m

-140m

100m
