Megaphone Buying Guide (UK Edition)
Whether you're leading a sports team, organising an event, managing a crowd, or coordinating safety operations, a megaphone is an essential tool for clear and powerful communication. Modern megaphones range from compact handheld models to high-powered, rechargeable systems designed for outdoor use. This guide will help you choose the right megaphone for your needs, explaining key features, specifications, and usage tips.
1. Power and Range
Output Power (Watts)
The power output, measured in watts (W), determines how loud a megaphone can be.
- 5–10 W – Suitable for small groups, classrooms, or indoor use.
- 15–25 W – Ideal for medium-sized gatherings such as sports training or community events.
- 30 W and above – Designed for large outdoor spaces, rallies, or emergency services.
Audible Range
Megaphones typically advertise a range in metres (m), which indicates how far your voice can be heard clearly.
- Up to 150 m – Compact, lightweight models for close-range communication.
- 150–400 m – Versatile mid-range models for outdoor activities.
- 400 m+ – Professional-grade megaphones for crowd control and long-distance projection.
