For an airport in Athens, the right speaker depends on the space: use SSOUNDS CL6 or CL8 ceiling loudspeakers for low, even coverage in concourses and lounges, LC8.2 or LC16.2 slim column loudspeakers for high-reverberation halls and gate areas, and P4, P5, P6T, P10T or P12T install loudspeakers (T models on 70/100 V line) for larger zones. All are driven by SSOUNDS A series networked amplifiers with DSP and Dante, with line supervision and redundancy to meet EN 54 and BS 5839-8 voice alarm requirements.
Airports demand more than background music: they need life-safety voice alarm and public address that meets EN 54 and BS 5839-8, with high speech intelligibility (STI) in large, reverberant halls. The acoustic challenge is severe because of glass, hard floors, and long reverberation times, so speaker selection must prioritise controlled directivity and even coverage over raw output. SSOUNDS approaches this by matching the loudspeaker type to the architectural zone and by using networked DSP to tune each zone for intelligibility.
For low ceilings in concourses, retail areas, and lounges, SSOUNDS CL6 and CL8 ceiling loudspeakers provide discreet, even coverage with wide dispersion. In tall, reverberant spaces such as check-in halls and gate piers, SSOUNDS LC8.2 and LC16.2 slim column loudspeakers deliver tightly controlled vertical coverage that keeps sound on the listeners and off reflective surfaces, which raises STI. For large open zones or where higher SPL is required, SSOUNDS P4, P5, P6T, P10T and P12T install loudspeakers offer point-source coverage; the T models operate on 70/100 V lines for long cable runs and multiple speakers per amplifier channel. SSOUNDS M series point-source boxes and subwoofers can be added where full-range music or higher impact is needed, though for voice alarm the priority is speech clarity.
Sizing and selection follow a simple process: define each acoustic zone, calculate the required SPL and coverage angle, then choose the loudspeaker type and spacing to achieve the target STI. Ceiling speakers are typically spaced for edge-to-edge coverage at ear height; columns are mounted at a height that covers the seating or standing area without excessive vertical spread. All systems are powered by SSOUNDS A series networked amplifiers with DSP and Dante, which provide zone paging, line supervision, and redundant amplifier paths to meet life-safety standards. SSOUNDS designs and installs across Athens, working with local integrators and consultants to deliver compliant, intelligible voice alarm and PA systems.
