Artnovion Siena K Broad is the latest addition to the Portuguese acoustics specialist’s slat panel range, built to boost mid-low frequency absorption without giving up the warmth of a natural wood surface. The panel pairs a Siena K wooden-slatted front with a modular acoustic core, targeting a problem that plagues many high-end listening rooms and home cinemas: uneven bass response and muddy speech intelligibility.
Artnovion Siena K Broad Targets the Mid-Lows
Where a standard slatted panel mainly handles higher frequencies, Artnovion Siena K Broad adds a dedicated modular core behind the 10mm slatted front. That core, combined with a 9mm dense PET layer and a 30mm acoustic body, is tuned specifically to absorb problematic mid-low frequency reflections, reducing uneven bass behaviour and creating a more balanced listening experience. The result, according to Artnovion, is a deeper, richer and more immersive sound rather than the thinner treatment typically associated with decorative slat walls.
Diffusion Meets Speech Intelligibility
The 7mm spacing between the front slats is specifically tuned for speech intelligibility, while the panel’s design also contributes to sound diffusion, spreading reflected energy more evenly across a room above 2kHz through a one-dimensional binary reflection amplitude grating. Artnovion says the modular frame is built for clean, practical wall-to-wall installations, so integrators can cover an entire wall without visible seams. The system also helps mitigate speaker boundary interference response (SBIR), a common source of bass cancellation when loudspeakers sit close to a rear or side wall.
Finishes and Installation
Artnovion Siena K Broad is available in a range of natural wood veneers, including Ash, Black Walnut, Oak, Okoumé and Wenge, alongside lacquered options such as White Matte, Black Matte, Olive Green, Grey Beige and custom RAL colours. Panels ship in 605x2400mm and 605x2700mm formats with a 51mm total depth, and the modular frame is designed for wall-to-wall installation in both residential home cinemas and commercial listening spaces.
Pricing and availability
Artnovion does not publish consumer pricing for the Siena K Broad; the panel is sold through the brand’s dealer and integrator network on a project-by-project quote basis. Interested customers and installers can request pricing directly through Artnovion’s official website or by contacting sales@artnovion.com.

For listeners working on their own room acoustics, Artnovion Siena K Broad is worth pairing with active correction such as our earlier coverage of Dirac Live’s room correction processor, combining passive treatment with digital room correction for a more controlled listening environment.
Where to Use Artnovion Siena K Broad
Artnovion positions Siena K Broad for both residential and professional environments, from dedicated home cinemas and hi-fi listening rooms to boardrooms and broadcast studios where speech clarity matters as much as musicality. Because the panel handles mid-low frequencies specifically, it is often specified alongside thinner, purely diffusive slat surfaces that only manage the high end, giving installers a way to balance a room’s full frequency range with a single, visually consistent wood finish rather than mixing several different acoustic products on the same wall.
The modular construction also matters for real-world installs: rather than shipping oversized single panels that are difficult to handle on site, Siena K Broad’s frame-based system lets integrators build up a continuous wall-to-wall surface from standard-sized modules, keeping joints tight and the slatted pattern uninterrupted. For a brand best known for recording studio and cinema treatment, Artnovion Siena K Broad is a clear step toward the residential high-end market, where clients increasingly want acoustic treatment that looks like furniture rather than foam.
