Diffuser 2D SKYLINE City

A spatial 2D diffuser that scatters unwanted reflections without damping the room's acoustic energy. The characteristic block layout helps limit flutter echo while creating a decorative city-skyline motif.

The spatial Skyline structure

Blocks of calculated heights form a surface that diffuses in two dimensions.

scatter_plot

Diffusion up to 9052 Hz

The 15 cm variant works from 548 Hz, and the 10 cm version from 823 Hz.

graphic_eq

No damping of the acoustic energy

The panel organizes reflections, helping keep the sound spacious and lively.

architecture

Wall or ceiling mounting

The plugs are included, and the ceiling kit is available on special request.

Acoustic data

More spaciousness, fewer harsh reflections

Skyline City uses a quadratic residue sequence and blocks of varying heights to scatter sound waves instead of absorbing them. It helps reduce flutter echo and unwanted reflections while preserving the room's acoustic energy.

823-9052 Hzrange of the 10 cm variant

2D Skylinediffusion in two dimensions

Flutter echo between parallel surfaces becomes less bothersome.
Reflections are spread more widely instead of returning in one direction.
The room can keep a lively sound without relying on absorption alone.
The 15 cm variant extends the declared operating range toward lower frequencies.

How it works and the diffusion band

A flat wall - a directional reflectionThe wave returns in a single direction; flutter echo arises between parallel walls. Illustrative diagram.

Skyline diffuser - scatteringBlocks of calculated heights reflect the wave with different delays - the reflection spreads across many directions. Illustrative diagram.

Operating band

15 cm

548 Hz 9052 Hz

10 cm

823 Hz 9052 Hz

The ranges result from the panel's geometry (the quadratic residue sequence and block heights) - these are design values, not measurements. For the 548-9052 Hz band this corresponds to wavelengths of approx. 63-4 cm. We will publish the scattering coefficient chart once measurements are made.

Construction

Three-dimensional geometry calculated for diffusion

Each element of the surface is part of a deliberate sequence that gives the panel both an acoustic function and a decorative rhythm.

Blocks of varying heights
The three-dimensional structure resembling a city skyline scatters waves in two dimensions.
A quadratic residue sequence
The element heights are calculated by an acoustic algorithm, and their arrangement is not random.
A furniture-board construction
The panel is made of precisely machined wood-based board in black.

Dimensions and prices

The same format, two operating ranges

Both variants measure 44 × 44 cm (±5 mm), and the price depends solely on the thickness.

Both variants share the same 44 × 44 cm front (±5 mm) - they differ in the blocks' depth: the 15 cm version reaches lower with its diffusion band (from 548 Hz), the 10 cm version is shallower and lighter (from 823 Hz).

Assembly

Installation in three simple steps

01design_services

Mark the position

Plan the panel's spot on the wall or ceiling where you want to scatter troublesome reflections.

02construction

Install the fixings

Use the included wall plugs; if you're planning a ceiling installation, order the dedicated kit on special request.

03check_circle

Hang and check the panel

Place the Skyline City on the fixings, level it and make sure the structure is stable.

The soundstage got noticeably wider and the flutter echo is gone. The skyline look is a nice bonus in my room.

Działa świetnie, mniej trzepoczących odbić i głębsza scena. Trochę droższy niż się spodziewałem, ale wygląd 'miasta' bezkonkurencyjny.

Die Bühne wirkt jetzt richtig dreidimensional und das Flatterecho ist weg. Das Skyline-Muster sieht dazu einfach stark aus.

La scène a vraiment gagné en profondeur, j'étais bluffé, et le flutter echo a quasiment disparu en plus le motif façon ville est superbe.

FAQ

Frequently asked questions

A diffuser scatters reflections and doesn’t damp the room’s acoustic energy. An absorber soaks up part of the wave’s energy, so the two treatment types serve different, complementary purposes.

The 10 cm variant has a declared range of 823-9052 Hz, and the 15 cm one 548-9052 Hz. The thicker panel extends the performance toward lower frequencies; you’ll find the prices of both versions in the Dimensions and prices section.

Yes. The three-dimensional structure scatters the waves and reduces flutter echo and unwanted reflections between parallel surfaces.

Yes, the product is meant for the wall and ceiling. Wall plugs are included, and a ceiling kit is available on special request.

The panel comes in one color – black. The configuration covers the thickness choice with a fixed 44 × 44 cm (±5 mm) format.

We’re preparing the scattering coefficient chart based on measurements. For now we state the declared operating ranges: 823-9052 Hz for the 10 cm version and 548-9052 Hz for the 15 cm one.

There’s no simple per-square-meter formula. The choice and placement are best based on the room’s geometry, the reflection points and an acoustic consultation – we’re happy to help in a free consultation.
