Sound columns and horns are sophisticated sound reinforcement devices with specially designed speakers and exacting formulas for construction, frequency response, and control of the sound distribution pattern.
Sound columns can cover a wide variety of speech applications as can horns.
In contrast, horns must be installed up high as not to cause feedback and then be aimed down towards the listening area. Although most churches have high ceilings, columns are often preferred over horns and hanging speaker clusters for aesthetic reasons. Conventional loudspeakers are recommended mostly for music applications and PA in smaller auditoriums where reverberation is not a significant factor. The Sound Columns are available in three different sizes, LS 4, LS 6 and LS 8, each with four - six and eight loudspeaker units respectively. The pie shaped sound column pattern focuses on the listener with little or no reverberation and echo.
