Linea Focus. Precision you can hear, hardware you barely see.
An 80 mm aluminium column housing individually amplified drivers, each under its own DSP. The sound field is shaped electronically — so the loudspeaker can be placed where the architecture allows, not where the aiming demands.
Explore the engineering behind the steered column — beam control, on-board DSP, and architectural integration.
Six reasons specifiers choose Fohhn.
Designed, developed and manufactured in Nürtingen, Germany — every driver, DSP board and enclosure held to a single tolerance standard.
Electronically steered line sources aim sound with degree-level precision — no mechanical tilt, no compromise on architecture.
Ultra-slim column profiles, custom RAL finishes and flush mounting details that disappear into stone, timber and glass.
Energy lands on the audience, not the ceiling — STI figures that hold up in marble halls and long reverberant spaces.
Fohhn-Net, Dante and AES67 with per-channel processing, presets and remote monitoring across the whole estate.
Neutral, uncoloured reproduction for speech and music alike — engineered rather than voiced for effect.
The Fohhn range, engineered as one system.

Where Fohhn systems are specified.
Every environment has a full application page — acoustic challenge, engineering approach, recommended stack, visual references and a pre-loaded coverage simulator.
The same room. Two entirely different acoustic outcomes.
Move the listener, change the room, and watch what happens to intelligibility when the sound field is shaped by DSP instead of by a bracket.
Stage position, seating slope and balcony geometry drive the design. Separate beams normally serve stalls and balcony.
Click any listening position to move the virtual listener · drag the array to change mounting height · every value is a design estimate until site measurement.
Showing the parameters that matter most for a auditorium. Switch to “Build my room” for the full geometry set.
Fixed vertical dispersion sprays energy at ceilings and rear walls. Reflections smear consonants.
Drag the array to set mounting height, drag the handle to steer, drag anywhere to move the listener.
Steered energy holds level across the seating plane instead of falling away behind the first rows — indicative design estimate, not a measurement.
Real programme material — a recorded announcement, a music bed or a pink-noise test signal — played through the current room, beam and noise settings.
Beam on the listener at 15 m — direct sound stays forward of the room tail, articulation holds at STI 0.88. Indicative sound design simulation, not a measurement or a Fohhn recording.
Dolby surround test
Channel-by-channel identification for a 5.1 / Atmos room. Tap any speaker to fire that channel, or run the full sweep.
Output routing is detected on first playback.
Beam locked on the listener — approx. +32 points of speech-intelligibility improvement versus a conventional system in the same room.
Drag inside the steered room to move the listener. Indicative simulation — not a measurement of a specific project.

Design simulation — estimated performance until site measurement
Run a full acoustic study — before a single speaker is specified.
Our own acoustic engine. Model the room, analyse project documents, calculate reverberation and intelligibility, configure the system and export a complete engineering study — all inside CaesarTechs.
Describe the room. We'll outline the system.
A first-pass concept from our engineering team's own rules of thumb — refined into a full design once we receive your drawings.
Indicative concept only — not a measured or engineered result.
Fohhn audio control architecture
Every Fohhn loudspeaker is an addressable, DSP-controlled device. Beam angles, levels, filters and presets live on the network — so a system can be re-tuned, re-zoned or extended without touching the ceiling.
Windows configuration and control software: beam design, FIR/IIR filtering, delay, limiter and preset management for every device on the network.
Fohhn's own control bus. One cable carries addressing, beam control and live monitoring for hundreds of devices — independent of the audio transport.
DSP amplifiers (DI-2.250 / DI-4.1000 / DI-8.1000) with onboard beam steering, matrix routing, EQ and protection per channel.
Standards-based audio transport so Fohhn zones sit inside the wider AV, paging and conferencing infrastructure without gateways.
Crestron, Extron and BMS drivers expose sources, levels, presets and mute groups on the panels operators already use.
Continuous device supervision with fault logging — CaesarTechs can review system health remotely under an SLA.
One signal chain, fully networked.

Fohhn Designer.
Every project is simulated before a single bracket is drilled. Import the room, place the systems, model the acoustics, optimise the beams, then push the DSP configuration straight to the amplifiers.
Manufacturer, distributor, integrator — clearly separated.
Designs, develops and manufactures the loudspeaker, DSP and amplification technology in Nürtingen, Germany. All product names and specifications belong to Fohhn.
Holds regional distribution for Fohhn, providing supply, technical enablement and manufacturer-backed support across the region.
Designs, integrates, commissions and supports Fohhn systems for projects in the Kingdom. CaesarTechs does not manufacture or re-brand Fohhn products.
