155 dB
Delivers up to 155 decibels at 1 metre, ensuring maximum power for long-range communication or deterrence.
Halo Long-Range Acoustic Device: HLAD 950
When you need the power to communicate, warn or deter across extreme distances, the Halo Long-Range Acoustic Device (HLAD) delivers. This next-generation sound cannon combines directional clarity with unmatched range, enabling long-range acoustic communication, crowd control, and non-lethal threat deterrence up to 3 kilometres away. Whether securing a superyacht, private estate, or high-risk perimeter, HLAD gives your team control before a threat gets close.
Why Choose Halo’s HLAD 950 System?
Full Force Acoustic Coverage
HLAD 950 delivers a peak acoustic output of ~155 dB and a continuous output of ~151 dB at 1 m, with a beamwidth of ±15° at 1 kHz. This enables pinpoint voice and alert projection up to 3,000 metres in a wide range of operational environments.
Precision Sound Cannon Technology
A focused sound cannon, HLAD uses patented XL driver technology to achieve unmatched audio clarity and range while minimising sound spill to surrounding areas.
Intelligent, Integrated Design
The HLAD 950 features TCP/IP remote control, an integrated HD camera with pan and tilt capabilities, and compatibility with radar, motion sensors, and automated threat detection systems for seamless escalation.

HLAD 950 FAQS
What is a long-range acoustic device (LRAD)?
A long-range acoustic device, or LRAD, is a directional sound system that emits powerful voice commands or deterrent tones across vast distances. It is used for communication, perimeter defence, and crowd control, providing clear audio over extreme ranges.
Is HLAD the same as an LRAD weapon?
HLAD is Halo’s advanced version of the LRAD system. While often referred to as a “sound cannon” or “acoustic weapon,” its primary purpose is non-lethal deterrence and long-distance communication. It gives security teams time, control, and flexible response options.
How far can HLAD be heard?
HLAD’s range extends beyond 3,000 metres in optimal conditions. It maintains clarity even in high wind, over engine noise, and within urban environments, making it ideal for maritime, remote, or high-risk locations.
Does HLAD cause permanent damage?
HLAD is a non-lethal system designed for safe escalation. When used correctly, it delivers strong deterrence without lasting harm. Output levels can be adjusted to suit operational needs, including close-range or crowd-safe scenarios.
Can HLAD be integrated with other security systems?
Yes. HLAD is built for modular deployment. It connects with surveillance platforms, AI-based detection systems, and remote control units. It works especially well when combined with Halo’s aerial, onboard, underwater defence, and HEMP technologies.
