The SM Series speaker systems also work well in a down firing configuration for spaces utilizing open beam ceilings such as offices,
restaurants and warehouses. When determining speaker spacing in down-firing installations, refer to the following chart:
Note: Using the above spacing suggestions will maintain good, even high frequency coverage, which translates into excellent intelligi-
bility for voice reproduction and high fidelity music reproduction. To find out more about the formulas used to determine ceiling
speaker spacing, check out the book Sound System Engineering by Don and Carolyn Davis. To find out more about the limits of
wide dispersion loudspeakers, download the Atlas Sound white paper on the subject at
