Sound projector loudspeakers are designed to deliver focused, long throw audio in environments where clear, directed sound is essential. Their slim, cylindrical or rectangular form allows audio to be projected accurately towards specific areas, reducing unwanted reflections and ensuring excellent speech intelligibility in acoustically challenging spaces.
These characteristics make sound projectors particularly well suited to corridors, tunnels, passageways and long enclosed spaces, where controlled dispersion helps maintain consistent volume and clarity from start to finish.
They are widely used in transport hubs, railway platforms, airports, underpasses, car parks, warehouses and industrial buildings, as well as large public buildings with high ceilings or reflective surfaces.
Many sound projector loudspeakers are suitable for voice alarm and public address systems, with selected models meeting EN54-24 requirements for use in life safety applications. This makes them an ideal choice for emergency announcements and evacuation systems, where intelligibility and reliability are critical. Most designs support 100V line operation, allowing efficient connection of multiple speakers over long cable runs.
Weather resistant and IP rated sound projectors are available for outdoor or semi exposed locations, offering dependable performance in harsh conditions.
With their combination of durability, clarity and directional control, sound projector loudspeakers provide a professional solution wherever targeted audio coverage is required.
Sound projectors fire a focused beam of speech along a path — corridors, tunnels, platforms, underpasses, car parks and warehouses — so announcements stay clear without flooding every reflective surface. They are a staple of public address and voice-alarm systems in transport hubs and industrial buildings.
A horn is a flared, high-efficiency pager for noisy yards and open air. A projector is usually a slim cylinder or rectangle that throws speech along a corridor or platform with tighter control and a more compact look. Use horns for wide industrial spaces; use projectors for long enclosed routes.
Specify a projector when the audience sits in a line (platform, passageway, high walkway) and a wall cabinet would bounce off hard surfaces. Cabinets are better for rooms where you want wider, more musical coverage.
A bi-directional projector fires both ways from one housing, so one unit can cover both directions of a corridor or platform. A uni-directional projector covers one way only. Choose bi-directional to cut speaker count on straight routes; choose uni-directional when you only need sound in one direction.
Yes. Most models are 100V line so you can daisy-chain long runs of projectors from one amplifier. Some also offer a low-impedance tap. Add up the selected wattage taps and leave headroom on the amplifier.
If the circuit is part of a life-safety or evacuation system, specify EN54-24 certified projectors. Standard paging projectors are fine for staff announcements but are not a substitute for certified voice-alarm loudspeakers.
IP-rated projectors (typically IP54–IP66 in this range) suit platforms, car parks and semi-exposed walkways. Keep cable glands tight and the cabinet aimed so water sheds off. Check the Tech Hub IP guide if you are unsure which rating you need.
Fix them along the run at a consistent height, aimed along the path of travel rather than straight at the opposite wall. Ceiling mount versions are available for use where a wall fix is not possible. Even spacing matters more than packing extra units close together.
They are built for speech intelligibility first. They can carry simple music on a mixed PA, but they will not sound like a two-way cabinet or performance speaker. For quality BGM in a concourse, pair projectors for paging with separate music speakers.
Commercial Audio Solutions can match uni- or bi-directional coverage, EN54-24, IP rating and 100V load. Call 01663 767888 or email sales@commercialaudiosolutions.com with the length of the route, indoor or outdoor, and whether the system is paging only or voice alarm.
