The Cube deep absorber is very easy to keep clean, it is enough to wipe it with a slightly damp cloth. 

Is the performance of the deep absorber measurable? 

There are free downloadable software to measure bass absorber performance. First perform the measurement without a low absorber, then place the deep damper in the appropriate part of the room (corner, for example) and repeat the measurement. You will not be disappointed in the deep absorbent of the Perfect Acoustic Cube and this will be confirmed by the measurements! It is not worth trying cheaper, poorer quality products, sponge or styrofoam materials.

How to use Cube sound traps?

Since bass tones accumulate mostly in the corners, it is advisable to place at least two bass traps on top of each other in each corner. Corner sound trap is recommended in the corners, if we have enough space for it, in case of lack of space we recommend narrower or custom sized acoustic panels. If that still doesn’t work, try placing it at the height of your ear. In this way, we can also control the secondary reflection point. 

“The die has been cast” 

The Cube low absorber eliminates the disproportion of sounds .

Panels acoustic options

Together with the bass trap broadband acoustic panel, we immediately experience a quality improvement. The bass calms down, the rattle echo decreases, and the standing waves responsible for highlights and extinctions disappear. The result will be a calmer, clearer sound due to a reduction in reflections and echoes. 


Do you want to enjoy truly perfect acoustics in your home, office or studio? Then be sure to have an acoustic test performed by a qualified professional. With the online measurement, we can quickly and smoothly test of the given room with 95% accuracy. It is not worth saving on acoustic measurements, we provide this service at a very reasonable price. With the help of accurate measurements, we can create the most optimal acoustics possible, and our premium quality acoustic panels, membranes, bass traps and other products meet all needs and requirements. Of course, we are also happy to help you choose the right acoustic panels. 

How do bass traps help create optimal acoustics? 

Bass traps play an important role in absorbing bass sounds. The sizes and shape of the room also affect the acoustics. Some frequencies are further amplified and others are extinguished. The cube bass trap was developed for just that purpose. Used it with broadband acoustic panels and diffusers, you can achieve a perfect, balanced air space. The best solution the panels acoustic optipns for noise absorption and soundproofing purposes.

Why has the use of sound-absorbing panels become so important? 

Too much bass in the studios 

Today, as a result of the rapid development of technology and science, we can make perfect sound and music recordings even in our homes, with the right tools and equipment, of course. Smaller, larger studios, halls, rooms are usually located in buildings that were not designed based on acoustic considerations at the time. The smaller the room, the more acoustic problems we may face. Due to the proximity of the walls to each other, the performance of speakers, speakers and instruments is impaired by very significant reflections. Rooms are most often rectangular or square in terms of their floor plan, with standing waves and rattle echoes due to the parallel walls. These negative acoustic effects disturb our ears to an extremely large extent. Broadband sound absorbing panels and soundproofing acoustic panels provide a solution to this problem. Managing bass frequencies is a much more serious task. When several phases combine, the bass is amplified at a certain frequency. These sound waves can complement and extinguish each other, thus reducing the frequency. As a result, the sound sources sound too quiet or too loud, depending on which part of the room we are in. If a room has optimal acoustics, we can experience a uniform sound in all parts with a negligible difference. 

I‘ve been around every corner …” 

The importance of acoustic treatment of corners should be mentioned again. Every acoustician starts the acoustic repair of a particular room with the corners. Since deep sounds accumulate in large amounts in the corners, it is absolutely justified to place bass traps. If you duplicate the amount of bass traps in the corners, they act as sound traps to absorb excessive bass sounds. Choose the best absorption acoustic panels from the  panels acoustic options.

“Teacher, please, I don’t understand that!” – or how can the membrane absorb deep sounds? 

It’s not rocket science. The dense, soundproofing membrane significantly slows down those intrusive depths with a silent vibration as the bass passes through. The thermodynamic effect of the absorption, dense, fibrous acoustic cotton inside the bass traps slows down the passing bass and then converts its acoustic energy into heat. If you have a problem below 600 Hz, you should use the soundproofing Giga bass trap. 

This all sounds great, but what about the higher frequencies? 

Trebles are easily absorbed by even the simplest, ordinary objects. Our furniture, curtains, all function as sound-absorbing devices, but bass sounds are already proving to be a great task for our furnishings. As the absorption of the bass range is the most difficult to control, however, it is essential to achieve the ideal surround sound, so the higher tones must also be sacrificed. Absorbed trebles can also be called a collateral damage. 

Even when placed behind a home theater curtain, our bass traps work perfectly as the deep sound passes unhindered through the curtain! 

The secrets of sounds 

Sounds are not just part of the music world. They are present in our everyday lives, such as speech and everyday, external noises. Not all sounds are audible to the human ear. There are certain frequencies that we cannot hear. As the sound propagates, its particles make a frictional motion. Depending on the distance, the sound constantly fades, loses its energy, and then dies completely. However, this sound energy is not lost, it is only converted into heat energy. 

The number of vibrations of the sounds is not the same, that of the deeper sounds is lower, while that of the trebles is correspondingly higher. During the propagation of high tones, it takes more energy to move the particles in the air, but in the case of deep tones, much less energy is required for the propagation. 

This shows that trebles gets a shorter distance, unlike bass. 

If there is a stronger sound effect in the immediate vicinity, we can hear a sharp, clicking sound, but the farther we hear the sound effect, the deeper, thicker sounds reach us. Because the sound closer is both bass and trebles, both sounds will be audible, but as the sound propagates farther away, the louder sounds with faster vibrations will weaken and eventually die completely. This way, only deep sounds with fewer vibrations will be heard. 


The transmission and reproduction of sound requires right equipments. Perhaps everyone knows and has used the most common speaker equipment, such as the speaker or loudspeaker. There are countless brands and types on the market, but we can’t find one that can transmit all the sounds heard throughout the entire sound range. 

 Why is it impossible to produce a speaker that can emit all treble and bass? 

The answer is given by the science of physics: because higher tones have high vibrational numbers, this rapid vibration can only be followed by small membranes, but deep sounds require a larger, rigid membrane that can no longer follow the highly vibrational numbers. 


Why do acoustic problems occur? 

When sounds start to vibrate in a room, they get to our ears, but they are soon reflected from the walls, the ceiling. The resulting sound will be confusing and unpleasant. This is actually the echo. 

When the waves of a sound reflected from a wall meet the original sound, troughs form where the sounds extinguish each other and amplify each other in other parts. This is called interference. Because of this, that particular sound is heard at different intensities in different parts of the room. We will hear the “own” voice of the room. This is unfavorable because when we make subsequent adjustments, corrections, tests to a recorded sound, and are placed next to or in front of the speaker, we may be at a point where the bass sounds extinguish each other. Obviously, this is when we raise the bass on the recording. But if we listen to this sound later in another location, we are shocked to find that excessive bass sounds suppress the other sounds, making the recorded material unenjoyable. It is therefore very important that the room, the room where the sound recording takes place, has a balanced, well-proportioned acoustics. 

Absorption and soundproofing panels acoustic options

 Acoustic foam has no sound absorption and soundproofing ability. Acoustic foam is not suitable for room treatment. If you want effective treatment in your home or office, choose from our sound absorption acoustic panels, which can achieve favorable results with effective sound absorption and soundproofing ability. We offer several options on our page from the best absorption and soundproofing acoustic panels. Purchasing the best noise absorption fabric and wall panel you can achieve the best results  in ideal acoustics. The best acoustic treatment can only be achieved with absorption and soundproofing acoustic panels, avoiding acoustic foam. Soundproofing curtains made of soundproofing fabric are used to operate the windows. By absorption noise, the best acoustics can be achieved in both the studio and the office. We use a dense absorption fabric for the soundproofing wall panel, there are many options on our web page.

What should we do to get the right acoustics for our studio? 

Of course, it’s not just the echoes that need to be attenuated. The attenuation of deep sounds is a very serious task, acoustic measurements, precise design and construction are required to ensure that the bass sounds do not predominate in the room. It is not recommended to crowd our walls with rock wool, egg boxes and other similar objects that can only absorb higher sounds as they are not able to absorb deep sounds. By placing bass traps, bass-absorbing membranes, diffusers, we can attenuate direct echoes and too much bass, thus achieving a pleasant, enjoyable sound and musical experience. By eliminating the rattle echo and curbing the deep sounds, we will have a truly exceptional surround sound. We will not make any errors in the tone control during the post-production after recording the audio. 

Remember that placing premium-quality acoustic devices with the right function is also important, because even if we buy excellent products to create the perfect acoustics, if we don’t place them in the right points in a given studio or room, they are less able to function at full efficiency! Perfect Acoustic also helps customers with the ideal placement of their products.

    The Cube acoustic panel is excellent both aesthetically and in terms of quality. My wife likes it too, though at first she was afraid she wouldn’t look good in the living room and take up too much space, but luckily she was pleasantly disappointed. The sound is perfect! Thanks!

Questions and answers of the customers

    Dear people of Perfect Acoustic, I've got a few questions about the Cube acoustical sound panels. The weight is 25 kg. Is this the weight of the biggest one? I'm interested in size 105 x 31 x 30 cm and I'm curious about the weight of these panels. My second question: is it possible to make a little cube panel for me if I order 2 big cube panels? A little cube panel of 30 (height) x 31 x 30 cm would be great, so that I can fill the whole corner from botton to the ceiling. Thanks for answering my questions! Best regards, Peter
