Introducing the Artcoustic SL C-4-1 Soundbar
Engineered for crystal-clear speech and effortless headrooM - A new centre solution that sounds bigger than it looks.
Although compact, the C-4-1 has the headroom and control that professional installers expect for premium projects.
At the heart of the C-4-1 Soundbar is a sophisticated five-driver array: four 3" long-throw midrange units flank a 2" high-definition ring-radiator tweeter. This layout delivers excellent speech intelligibility with pinpoint vocal accuracy and minimal distortion, even at elevated listening levels. High-frequency performance is notably extended, with response up to 40 kHz and a sensitivity around 98 dB (1W/1m, ±2 dB), giving you clean output and effortless dynamics from a slim enclosure.
While conceived as a compact centre for home cinema, the C-4-1 is equally comfortable beyond the theatre. Rotate it vertically and it becomes a refined on-wall loudspeaker for media rooms and living spaces—ideal wherever the brief demands both performance and a discreet footprint.
“When I set out to design the C-4-1, I had one clear ambition: to create a compact speaker that could disappear into a room visually, yet remain absolutely uncompromising sonically. In cinema, dialogue is everything — it carries the story, the emotion, the connection. I wanted every word to be reproduced with exceptional clarity and presence, even in spaces where size and placement are limited.
The C-4-1 was engineered from the ground up to achieve this balance. By combining a high-definition ring radiator tweeter with four precision long-throw midrange drivers, we’ve created a system capable of remarkable accuracy, wide dispersion, and dynamic output — performance that belies its discreet form factor.
For me, this product reflects what Artcoustic has always stood for: the harmony of engineering precision, aesthetic integration, and real-world usability. The C-4-1 is not just another compact loudspeaker — it is proof that when design and technology work together, you don’t have to choose between form and performance.

MULTIPLE OPTIONS
Thanks to Artcoustic’s modular baffle system, the soundbar aligns neatly with displays and architectural elements for a tailored, built-in look. The shallow profile supports multiple installation paths, including on-wall, in-wall, and free-standing, so you can specify the same acoustic signature across diverse room concepts.
Aesthetics are as flexible as the acoustics. Choose standard black or white, or specify any NCS 1950/2050 or RAL Classic colour to match the interior. This level of finish control lets you maintain a consistent design language throughout the project, preserving the clean Scandinavian lines that define Artcoustic.
