Wall-mounted line arrays for clear speech in public spaces
A family of wall-mounted line array loudspeakers designed for public address and voice announcement applications in transportation facilities, commercial buildings and other public environments. Combining controlled directivity, wide horizontal coverage and a discreet architectural design, the range delivers excellent speech intelligibility.
For both indoor and outdoor installations, Wall Line features integrated 70V / 100V transformers for easy deployment in distributed audio systems. Available in three different lengths, the family allows consultants and system integrators to optimize coverage according to listening distance and installation requirements.
Pure Array Technology (PAT)
By combining multiple closely spaced transducers into a coherent acoustic source, PAT provides uniform coverage, controlled directivity and reduced unwanted reflections, helping maintain consistent performance and speech intelligibility throughout the listening area.
Slim Array Technology (SAT)
SAT provides controlled sound dispersion over long distances. Its slim array configuration delivers narrow vertical coverage and a more linear, consistent sound distribution, while allowing multiple modules to be combined into scalable arrays of different sizes and lengths.
WALL42T
The most compact model, ideal for short listening distances and smaller public spaces requiring discreet installation and controlled coverage
Transducers: 4 × 2" ferrite full-range transducers
Frequency response: 160 Hz – 20 kHz (-6 dB)
Maximum SPL: 102 dB (peak)
Coverage: 25° V | 90° H
WALL82T
For medium-sized installations, it offers increased output and tighter vertical beam control while maintaining wide horizontal coverage for uniform speech distribution
Transducers: 8 × 2" ferrite full-range transducers
Frequency response: 150 Hz – 20 kHz (-6 dB)
Maximum SPL: 109 dB (peak)
Coverage: 15° V | 90° H
WALL822T
Dipole/bidirectional asymmetrical loudspeaker system featuring two fixed-angle loudspeakers and an integrated wall-mounting bracket
Transducers: (8+8) x2” ferrite magnet woofers - dipole line array emission
Frequency Response: 160Hz - 20kHz (-10dB)
Max SPL: 114dB (peak)
Coverage: Dipole V.10° | H.90°
WALL162T
The largest model, engineered for applications requiring longer throw distances, higher output and the narrowest vertical coverage for maximum acoustic control
Transducers: 16 × 2" ferrite full-range transducers
Frequency response: 135 Hz – 20 kHz (-6 dB)
Maximum SPL: 115 dB (peak)
Coverage: 7° V | 90° H
