ContinueProjection Speakers — For Long Corridors in Tbilisi
Projection Speakers (Sound Projectors) are special directional audio devices designed for sound transmission over long distance in narrow spaces — corridors, tunnels, station platforms, stadium galleries in Tbilisi and throughout Georgia. These speakers are ideal for any facility requiring sound transmission 50-150 meters in narrow space — metro stations (platforms, corridors), railway stations (platforms, tunnels), airports (long corridors), stadiums (galleries, stairs), warehouses (long corridors), tunnels (vehicle, pedestrian). LAGI offers projection speakers with full functionality: 10W-50W power, 100V Line technology, Horn design (directional sound), frequency range 200Hz-15kHz, 95-105dB sound level, 50-150m distance, IP65 protection (dust, water), aluminum/stainless steel housing, wall/ceiling mounting bracket, adjustable angle (0°-90°). All models comply with CE standard.
Main Advantages of Projection Speakers
- Directional sound — Horn design focuses sound in one direction, sound transmitted 50-150m distance.
- Long distance — ideal for long corridors, tunnels, platforms.
- Less reverberation — directional sound reduces echo and reverberation in narrow spaces.
- High sound level — 95-105dB, audible in noisy environment (train, transport).
- IP65 protection — dust, water, humidity, ideal for outdoor conditions.
- 100V Line — low losses over long distance, can connect several hundred speakers.
FAQ — Frequently Asked Questions
Regular speaker (ceiling, wall) — sound disperses 360° or 180° (all directions), short distance (5-15m), ideal for regular rooms. Projection speaker (Sound Projector) — sound focused in one direction (30°-60° angle), long distance (50-150m), ideal for long corridors, tunnels. How it works: projection speaker uses Horn design (horn conductor), Horn focuses sound waves in one direction (like light projector), sound transmitted long distance with low losses. Advantages: long distance (50-150m), less reverberation (sound doesn't reflect from walls), high sound level (focused energy), economical (fewer speakers required). Application: long corridors (50m+), tunnels, station platforms, stadium galleries.
Projection speaker placement in long corridor — 1) Calculate speaker quantity: each projection speaker covers 50-150m distance (depends on power and acoustics), example: 200m corridor → 2-4 projection speakers (each 50-100m). 2) Placement: place speakers at one end of corridor or both ends, direct speakers along corridor (not across), install speakers on ceiling or wall (2.5-3m height), set angle with adjustable bracket (0°-15° down). 3) Zone division: long corridors (200m+) divide into zones (zone 1: 0-100m, zone 2: 100-200m), each zone has own speakers, can broadcast to specific zone. 4) Testing: check sound level at all points (start, middle, end), adjust power and angle. Tip: use IP65 speakers (for outdoor conditions), add 20% reserve power.
Yes, projection speakers are ideal for stadium galleries — stadium galleries: long narrow spaces (50-200m), high noise (fans, sirens), complex acoustics (echo, reverberation). Problem with regular speakers: regular speakers (ceiling, wall) don't cover long distance, sound lost after 20-30m, requires very many speakers (expensive, complex installation), strong reverberation (sound blurred). Solution with projection speakers: place projection speakers at one end of gallery, direct along gallery, sound transmitted 50-150m distance, fewer speakers required (economical), less reverberation (directional sound). Placement: install speakers on gallery ceiling (3-4m height), set angle with adjustable bracket (10°-15° down), use IP65 speakers (outdoor conditions). This allows providing clear announcements throughout gallery — evacuation instructions, announcements, music.
