HSM exclusive 18 foot Power Horn Tower portable tripod stand.
portable Paging/Announcement Power Horns for wide area coverage. These types of horns (speakers) can be seen at racetracks,
ballparks, car dealerships, large factories, etc.
Power horns are specifically designed to project the human voice
great distances by only reproducing a narrow band of frequencies at approximately 500 to 4,000 Hz (Hertz or cycles/per/second).
This range is where the bulk of the "understandable intelligence" is carried in normal conversation, and in general,
everyone at all ages can hear within this band.
Their design also allows the voice to pierce or cut-thru
sounds or noise and be heard over greater distances than conventional music speakers.
Faithful reproduction of music
on the other hand, requires a much wider audio band of 40 thru 15,000Hz.
Powerhorns cannot reproduce this wide frequency
Playing music continuously thru powerhorns will eventually result in listener ear fatigue, and people will tend
to migrate away from the horns.
Powerhorns are best suited for short, occasional announcements, ballplayer introductions,
parade narratives, door prize raffles, lost and found, etc. when you have to "cut-thru" the crowd noise.
HSM exclusive 3-Power Horn Portable Cluster provides 360 degrees of coverage
and sits atop our 18 foot tripod stand. Whenever possible, the announcers microphone is located in the rear area without coverage
to reduce or eliminate feedback. (270 degree coverage area shown in the above picture.)
Placing the 18 foot tripod
stand at the edge of the event will leave a 20 foot safety zone beneath the horns.
If the tripod stand must be placed
within the area of the event, the base of the tripod must be held down with anchors in the earth or pavement.
horn can be added for full 360 degree coverage if the situation arises where the Power Horn Tower must be placed in the center
of the activities, in lieu of the preferred location at the edge of the activities.
The horns can be positioned vertically
or horizontally. (Vertical position shown in the picture above.)
The can also rotate from pointing down approximately
20 degrees to pointing up approximately 160 degrees.
