Amplivox Indoor/Outdoor 100W Power Horn Speaker
Introduction
For use in public address or paging applications, the AmpliVox S1270 Indoor/Outdoor 100 Watt Paging Power Horn Speaker is a very audible, lightweight horn speaker. It is perfect for workplaces including schools, factories, offices, conference centers, and sports arenas. This PA speaker is built to last. A durable 1.5 in. dia. voice coil and ceramic magnet structure are used in the double re-entrant horn with a compression driver for extended life and dependability under difficult working conditions. In challenging applications, an ideal coverage pattern of 60° horizontal by 40° vertical (horizontal mount) is available. Additionally, the positive lock and extremely durable metal swivel base offer the greatest mounting versatility and simplicity of installation. With its single locking pin, it is movable in both horizontal and vertical planes (90° tilt, 360° rotation).

INSTALLATION INSTRUCTIONS
- Adjustment: The S1270 is constructed with a pivoting, cast iron base. Loosen the wing nut connecting the base to the horn and remove the base. With a screwdriver, loosen the screw on the back of the speaker if you wish to rotate the horn between vertical and horizontal positions. Tighten the screw securely when the desired position is reached.
- BASE: The base contains 3 holes for screws (not included). Use screws with greater than 1/4” diameter head to ensure safe installation. Screw the base to the mounting surface where you wish to install the horn. Reattach the horn to the base, rotate the horn to your de- sired angle and tighten the wing nut securely.
- Wiring: To aid weatherproofing, the wire connections are sealed internally, and accessible through a 20” lead. Connect the Brown (positive) and Black (negative/ground) wires to the corresponding 8-ohm outputs on your amplifier.
- If you wish to use the tamper loop functionality, connect the Red and Green wires to the appropriate circuit in your alarm system. If the circuit is broken, an alarm can be triggered. This is normally a closed (NC) circuit

Frequently Asked Questions
The horn assists to increase the coupling effectiveness between the air and the speaker driver. When it comes to impedance matching between the relatively thick diaphragm material and the less dense air, the horn can be compared to an “acoustic transformer.” Greater acoustic output power from a given driver is the end consequence.
In contrast to, say, a cone diaphragm, a horn speaker’s diaphragm doesn’t need to oscillate as often to produce a loud sound, making horn speakers a very efficient design. Horns are still employed in PA speakers for making announcements and sending out warning signals due to their high efficiency.
Hearing horns amplify sounds when waves are reflected into a gradually smaller region, increasing the sound pressure that reaches the ear [21,22], whereas speaking horns do so by matching the acoustic impedance of outgoing sounds to the surrounding air [20].
Horn loudspeakers are utilized either as a self-contained unit or as a component of a loudspeaker system in sound systems for streets, squares, motion picture theatres, and other big locations due to their high efficiency (up to 20%).
There is some correlation between speaker size and speaker loudness. The louder a speaker can get, especially with older sound systems, the bigger the speaker’s circumference. The maximum volume of sound that can be pushed out of speakers grows along with the physical diameter of the speakers.
The speaker’s transducer components, or speaker drivers, are ultimately in charge of transforming the audio signal (electrical energy) into sound (mechanical wave energy).
The number of decibels (dB) of sound pressure level (SPL) per watt of amplifier power, measured at one meter from the speaker, is used to describe speaker sensitivity. Manufacturers typically omit the SPL/W/M and merely use dB to simplify.
The computation is simple if the impedance of each parallel speaker is the same. Divide the impedance by the quantity of parallel speakers. Example 1: Parallel placement of four 8 ohm speakers 8/4 Equals 2 ohms, or eight to four. Example 2: Two parallel 4 ohm speakers: 4 divided by 2 equals 2 ohms.
If you don’t have a manual, look on the speaker box’s back. If you don’t have your instruction book, your speaker should have a plate or sticker with the wattage, voltage, and amperage listed on it. You may find this information by turning the speaker box around. Under wattage, there will typically be a range of figures listed.
Scream into a cone-shaped piece of paper to make it seem louder. This is a simple illustration of a real-world horn. The trumpet or the trombone are additional, more logical examples.
