EdgeMax Loudspeaker Overview
Surface-mounted loudspeakers do not oer the same aesthetic advantage, but are preferred
when consistent tonal balance across the coverage area is the primary design objective. This is
due to the physical nature of how surface-mounted loudspeakers project sound.
Despite these performance benefits, in-ceiling loudspeaker designs are still heavily preferred
due to the aesthetic preference of architects and interior designers looking to minimize the
appearance of loudspeakers.

loudspeakers must be closely spaced together.
Typically, the best performing types of surface-mounted loudspeakers are two-way products
with a high-frequency section that delivers controlled coverage angles, and a ported
enclosure for low-frequency reproduction. This arrangement results delivers more consistent
high-frequency coverage and balanced frequency response to a larger area. In addition,
surface mounted loudspeakers benefit from boundary loading, further improving the low
frequency response of the system.
