Vehicle sound systems, megaphones and loudspeakers

The choice of power mainly depends on the required range and your usage environment. Our range of professional megaphones extends from 20W to 65W, offering ranges from 60 meters to 1500 meters depending on the models.

For indoor use or over short distances, a 20W to 25W megaphone will be sufficient. For medium-sized outdoor events, favor a 40W to 50W model with a range of up to 1200 meters. For very large events and major gatherings, opt for a powerful megaphone of over 60W such as the MKS-65BAT.

It is important to note that the range does not only depend on the wattage, but also on the technology of the horn and the speaker used. Take into account disruptive elements such as ambient noise, wind, or obstacles that reduce the effective range.

On a noisy construction site or during a large demonstration, a minimum power of 50W guarantees optimal audibility even in difficult conditions. Portable voice amplifiers, with powers from 10W to 20W, are more suitable for teachers, guides, or trainers addressing groups of 20 to 50 people over a distance of approximately 60 meters.

Although often used as synonyms, these terms originally refer to distinct equipment. The traditional speaking trumpet is a passive, cone-shaped acoustic device that naturally amplifies the voice without electricity by increasing acoustic impedance.

The megaphone is the electric version of the speaking trumpet, equipped with a microphone, an amplifier, and a speaker to project the voice over long distances.

The voice amplifier, although based on the same amplification technology, is distinguished by its compact and portable format. It is worn on the belt and generally features a headset microphone, making it ergonomic for prolonged use.

Teachers, tour guides, and trainers prefer it because it allows them to speak without straining their voice while keeping their hands free. Today, in professional language, "megaphone" and "bullhorn" have become interchangeable to designate electric horn models.

A professional megaphone is essential in many contexts where vocal communication must carry far or cut through a noisy environment. During demonstrations, gatherings, or large-scale public events, a megaphone-type speaker of 50W to 65W allows organizers to transmit clear instructions to a large crowd over more than 1000 meters.

Security services, police, and prevention agents favor models of at least 40W for emergency evacuations, flow management, or interventions on public roads.

On construction sites and industrial sites, a 40W to 50W megaphone is essential to coordinate teams despite the noise of machines and ensure safety by communicating alerts over large areas. For medium-sized outdoor sports or cultural events, a 25W to 40W model is usually sufficient. Guides during tours of large heritage sites prefer compact 20W voice amplifiers like the WAP-20 for their ergonomics.

The battery life of a professional megaphone varies depending on the power supply type and usage intensity. Battery-operated models generally offer between 6 and 10 hours of continuous use at a moderate volume. Megaphones with a rechargeable lithium battery, like our 65W MKS65BAT model, offer a battery life of around 10 hours, which covers a full day of events or demonstrations.

This duration can fluctuate depending on several factors: the volume level (maximum volume consumes more energy), the use of additional features like the siren or audio playback via USB/SD, and conditions. For intensive use or long-lasting events.

Portable voice amplifiers from 10W to 20W offer similar battery life, sufficient for a full day of classes or guiding without interruption. Always keep spare batteries or a fully charged battery for critical uses in security or on construction sites.
