ContinueColumn Speakers — Directional Audio Systems in Tbilisi
Column Speakers (Line Array Speakers / Acoustic Columns) are professional audio systems designed for acoustically challenging spaces and provide directional sound delivery over long distances, ideal for churches, train stations, airports, conference halls, and public buildings in Tbilisi and throughout Georgia. These speakers provide high speech intelligibility (90%+, critical for voice announcements), directional sound coverage (vertical angle 10°-30°, horizontal 120°-180°, sound directed forward, not toward ceiling), long-range coverage (20-50m distance, ideal for long halls), reverberation reduction (less reflection from walls and ceiling, important for churches, stations), aesthetic design (vertical column 50cm-150cm height, white/black aluminum housing), and easy installation (wall or ceiling mounting bracket), making them ideal for churches (high ceiling, reverberation), train stations and airports (voice announcements), conference halls (speech intelligibility), museums and galleries (aesthetic design), courts and councils (speech clarity). LAGI offers a complete range of column speakers: 20W-40W columns (medium size 60-80cm, 4-6 drivers, churches, conference halls), 60W-100W columns (large size 100-150cm, 8-12 drivers, stations, airports), 2-way columns (woofer array + tweeter array, better quality), full-range columns (single driver type, economical), IP54/IP65 weatherproof models (outdoor spaces, stadiums). All speakers are compatible with 100V/70V PA systems.
Main Types of Column Speakers
- 20W-40W columns — medium power, 60-80cm height, 4-6 drivers (3"-4"), 15-25m coverage, ideal for churches, conference halls, museums, most common type.
- 60W-100W columns — high power, 100-150cm height, 8-12 drivers (4"-5"), 30-50m coverage, ideal for train stations, airports, large conference halls, stadiums.
- 2-way columns — woofer array (low frequencies, 4-8 drivers) + tweeter array (high frequencies, 2-4 drivers), better sound quality, wide frequency range 80Hz-18kHz, ideal for music, conference halls.
- Full-range columns — single driver type (4-12 units, 3"-4"), economical, good speech intelligibility, ideal for voice announcements, stations, churches.
- IP54/IP65 weatherproof columns — aluminum housing, waterproof drivers, -20°C to +60°C, ideal for outdoor spaces, stadiums, parks, open conference halls.
- Compact columns — small size 40-60cm, 3-4 drivers, 10W-20W, ideal for small churches, conference rooms, museums where space is limited.
Frequently Asked Questions
Column speakers are ideal for churches for several reasons: 1) reverberation reduction — churches have high ceilings (5-15m) and hard surfaces (stone, marble), causing strong reverberation (echo). Column speakers have narrow vertical angle (10°-30°), meaning sound is directed forward (toward listeners), not toward ceiling or floor, reducing reflections and reverberation by 50-70%. 2) long-range coverage — churches are often long (20-50m), column speakers provide focused sound over long distances (line array effect), one column covers 20-40m. 3) speech intelligibility — for understanding sermons, speech intelligibility must be >85%, column speakers achieve 90-95% thanks to reverberation reduction. 4) aesthetics — vertical design is harmonious with church architecture (columns, arches). Recommendation: for churches use 2-4 column speakers (30W-40W) instead of 10-20 ceiling speakers.
Column speakers — vertical array (4-12 drivers vertically), narrow vertical angle (10°-30°), wide horizontal angle (120°-180°), long-range coverage (20-50m), high speech intelligibility (90%+), reduces reverberation, ideal for acoustically challenging spaces (churches, stations, high ceiling), more expensive. Wall speakers — 1-2 drivers, wide angle (90°-120° vertically and horizontally), short coverage (10-20m), good quality but not ideal for challenging acoustics, ideal for regular spaces (restaurants, cafes, stores), economical. Recommendation: column speakers — acoustically challenging spaces, speech clarity critical. Wall speakers — regular spaces, background music.
Installing column speakers requires precise positioning. Steps: 1) planning — determine speaker positions (typically on front wall or columns, 3-4m height, aim toward rear listeners), calculate quantity (one 40W column per 20-30m² or 25-40m length). 2) mounting bracket installation — column speakers have special mounting bracket (wall or ceiling), install bracket securely (4-6 screws, strong dowel, speaker weighs 5-15kg). 3) angle adjustment — bracket has tilt adjustment (0°-30° down), set angle so sound aims toward rear listeners (not ceiling). 4) cable routing — run speaker cable (2-core, 2.5mm² or 4mm² for high power) from amplifier to each column. 5) connection — connect cable (+ and -), on 100V columns select power (tap selector: 20W/30W/40W). 6) testing — turn on system, check speech intelligibility from different positions, adjust angle if needed.
