Hybrid Acoustic Diffuser

This unique hybrid acoustic diffuser improves room acoustics. It evenly disperses sound reflections and its pattern is adapted to natural room properties. It improves elocution clarity and instrument separation, the perception of the space becomes brighter, the contours of the instruments are more detailed and clearer.

Even with the best audio system, you will not achieve good results in poor acoustic conditions. Improve your room acoustics materially.

Product description

Hybrid Acoustic Diffuser

Audio and Acoustics

Your hearing does not perceive sound only in a direct line in the axis of the speaker, what we hear is also a lot of reflections from the walls of the listening space. Room acoustics has a fundamental influence on the perception of music. That is why quality audio and acoustics are inseparable and a diffuser plays a very important role in the relationship. Even relatively good acoustic conditions deserve to be improved by acoustic treatment. Sound reflections from large flat surfaces like walls worsen sound clarity and intelligibility. The diffuser evenly disperses unwanted sound reflections. Thanks to this, elocution becomes clearer, the recording gain more spatiality and clarity. Details previously hidden come forward.

Improve Acoustics in Modern Interiors

Modern living frequently omits dealing with acoustics, unfortunately so, as acoustics have a fundamental effect on our psychological well-being. Long duration of reverberation interferes with clarity and intelligibility of speech and worsens spatial localisation of our hearing. Living spaces usually lack in acoustically absorptive materials. With modern minimalist interiors without carpets, their absence is virtually woeful.

The duration of reverberation is the main acoustic parameter of closed space. It is quite easily measurable and it should fall within the range of 0.2 to 0.5 seconds. A space that is overly damped feels oppressive. Conversely, in a space with no damping at all, one can hear considerable echo, for example the unpleasant reverberation sound of a teaspoon clink. Reverberation time can be regulated by changing the amount of acoustically absorptive materials, such as thick curtains, carpets, fabric upholstered sofas, etc.

Hybrid Diffuser in a Room

Compared to other acoustic solutions, a hybrid diffuser diffuses sound waves in one plane and absorbs them in the other. The patterns are optimised in such a way that enough acoustic energy is always kept in the room. Also, the ratio of absorption to diffusion can be to some extent controlled using variations of the basic pattern. On top of that, the diffuser is adapted to natural properties of a room: it suppresses unwanted standing waves thanks to differences in the density of the pattern. A well chosen hybrid diffuser can therefore substitute for a combination of different acoustic solutions that one would otherwise have to combine.

Custom Diffusers for Demanding Audiophiles

The size and volume of the listening space is directly related to the optimal size of the diffuser. In larger spaces, an appropriately sized diffuser will contribute significantly to the improvement of acoustic conditions. Contact us and we will produce a custom-sized diffuser especially for your room! The diffuser can also be stained in any shade desired as long as it is darker than the default natural treatment shade. In lighter versions (for example white), the oak wood segments layer is replaced by a quality plastic layer (the frame stays oak wood).



Acoustic Diffuser QRD67
€ 11 154

Acoustic diffuser prevents unwanted sound wave reflections in the listening space. Intended for demanding hifi listeners, it improves the overall acoustics of the listening space. Instead of absorbing the sound waves, as usual isolation does, they are evenly diffused.

Unique acoustic solution – make your room sound better

High End Speakers Evolution
€ 21 175

Our high end speakers Evolution were created with the intent of redefining what “faithful stereo sound” means. Their sound is characterized by full details, precise instrument localization and spatiality. They contain only one high sensitivity driver, complemented by a unique horn cabinet.

Inspired by the past, formed by the present.

High End Speakers Euphoria
€ 16 618

An original solution. A baffle optimised without any construction compromises and a range of empirical tests both contributed to the creation of these high end audiophile stereo speakers which deliver very detailed sound with a powerful bass component. They take advantage of the ideal properties of a full-range driver. The detailed elocution is complemented by excellent spatiality and instrument localisation.

Taste the littlest of details.

What you may want to know


How should the diffuser be placed?

We recommend placing the diffuser on the front wall of the listening room between the speakers, or on the back wall behind the listening spot, or symmetrically on the side walls of the room. Even the largest version is mounted simply by hanging on the wall (hooks are prepared on the back side). The strength of the wall fixing has to correspond to the weight of the diffuser. You will receive the diffuser either in one piece, or, in case of the larger sizes, in two pieces which you easily click together and fix with an enclosed screw.

Further, the diffuser can be placed horizontally or vertically. This depends on the resonant frequencies of the given room that we want to suppress (see our article on acoustics). If you need help choosing, we will be happy to advise you. Placed horizontally (the acoustic segments are placed horizontally), the diffusers dampens acoustic waves reflected from the ceiling and floor. With vertical placement (acoustic segments placed vertically), it primarily dampens waves reflected from walls.

How do I find out what effect the diffuser will have in my room?

While the diffuser pattern itself is mathematically defined and countable, predicting an actual direct and precise effect of a diffuser that is as complex as this one is, compared to simple-shaped diffusers that do not adapt to room properties, effectively impossible. Its effect is of course measurable to a certain degree once in place, but mainly, it will always be hearable. In practice, the choice of the diffuser ex-ante is governed by the most important room parameters: in this case the ratio of acoustically absorptive and reflective materials that are/will be present there, the size of the room and its modal frequencies. You can learn more about these parameters in several Audio Blog articles that cover acoustics, or we can advise you.

What is the diffuser made of?

The front exposed side of the diffuser is made up of acoustic segments, which together create a 17 cm deep diffusion pattern. The pattern is set in a solid oak wood frame. On their front side, the segments (made of acoustic foam) are completed by a thin layer of oak wood, treated and conserved with natural oil and wax.
