The properties of our Corner bass trap with double membrane :
Our Bass absorber with double membrane is made of dense acoustic imitation of leather material .
Its stiffness is ensured by the rigid wood construction.
We use 90kg/m3 acoustic wool for the internal sound absorption. It was developed especially for this purpose and it is harmless for the health.
If you want to order with a wooden membrane, please include it in the comment when ordering and what fabric you are requesting the wooden membrane for!
The surface is covered with acoustic velvet which prevents dust emission.
The touch, the look, the texture of the imitation of leather is identical to the real leather.
Bass traps with double membrane (corner) colour:
You can even request a patterned cotton fabric:

Wipe it with slightly wet cloth.
What is it good for and where to place it?
You can get an answer to this question in this article.
In which area our Bass trap with double membrane (corner) betters other products?
Thanks to the combination of wood and leather its sound absorption over 600Hz is marginal while it is significantly more effective in the lower ranges
Since it destroys the unwanted bass from 30Hz we will hear more detailed and controlled bass while higher wavelengths will remain airier and more spacious.
The acoustic double wood membrane mitigates only the low ranges. In this frequency range it is significantly more effective than any other acoustic panel.
If there is too much bass in the room it can squeeze out the trebles upsetting the acoustic balance of the room.
With the use of membrane bass trap it is almost impossible to overdo the dampening of the room, especially compared to broad range acoustic elements.
Therefore, one should not be afraid of purchasing too many membrane bass traps since bass ranges dominate the sound in every room.
The quality of audio recording in a home studio can only be the best if we create the best acoustics according to the audio experts as well. Acoustic foam and other similarly structured foams are not capable of creating top acoustics. Acoustic treatment is required to create ideal acoustics. This is perhaps the most important thing in an audio studio while recording audio. Even if we get the best studio speaker, without perfect acoustics, the end result will not be right. Try to achieve the perfect frequency response. Sounds should be controlled during acoustic treatment.
Acoustic foam and other foams are not good sound absorbers due to their structure. Let’s skip these out instead. The best soundproofing accessories contain acoustic cotton.
The sound absorption characteristics of the wood membrane bass traps:
The photo below shows the measurement result of a 109x64x22cm membrane bass absorber.
The photo illustrates that our membrane bass absorber is the most effective in dampening the low frequencies.30-150Hz
The acoustic characteristics of the double leather membrane bass trap:
The difference between the leather and the wood membrane is that the leather membrane can mitigate the higher ranges up to 600Hz.
To identify which part of the frequency range is the most critical one we can measure it or decide by ear tests.
You can also order custom sized membrane bass traps! If the dimensions of the custom sized bass trap are not larger than our standard ones we don’t charge any extra cost.
You can also order wood membrane bass trap as a printed acoustic panel.
You can send us your own photo by e-mail or choose one among the 50 photos shown on the page of printed soundproofing panels.
The placement of the wood membrane bass trap
Their shape is 45 degree angled which perfectly fits in any corner.
Every wood membrane bass trap corner unit stands on 5 cm high wooden feet. In case you would like to order one with higher feet or place them in a custom-made position, e.g. the trim of the parquet is higher or thicker than the average, please contact our professional and he will make custom sized feet for you without any extra cost.
You can cease or improve these anomalies by placing bass traps in corners.
I heard it many times that wood and leather do not suit acoustic treatment purposes since the sound cannot go through them.
Luckily it is not the case!
If the sound did not go through them then by applying simple acoustic imitation of leather we could prevent that our neighbours hear our favourite music when we turn up the volume a bit. If it were true it would be the simplest sound insulation solution in the world.
Naturally sound waves do go through them. But luckily not at every frequency. Every material has its own sound absorbing and sound transmission coefficients.
Taking into account these factors we design our membrane bass traps in order to become the most effective ones and with the goal to leave the trebles untouched since above 600hz the sound waves really won’t go through the leather material. By this we can ensure perfect linearity in sounding of studios, hi-fi and home theatre rooms.
For example, if the furniture and the carpets overdampen the trebles compared to the bass in a specific room then we can apply imitation of leather or wood membrane. Before placing these units into the room, we can easily identify the acoustic anomalies by running an acoustic measurement.
Here you can see a RT60 reverberation time with uneven sound transmission
On the graph above you can see the overdampening of high frequencies within a room while the low ranges are continuously rising, squeezing out the high frequency and the real bass. In this case not the real bass would exceed but its reverberation. It creates an undynamic, continuously rumbling bass which can hide the details.
In this case if we place in the corner one or more imitation of leather or wood membrane bass traps the reverberation would decrease significantly, but only at the lower frequencies thanks to the membranes.
If we use standard broadband bass traps in such case, the trebles would go down as well parallel with reverberation which is not a preferred result if we would like to achieve the most even sound.
If you live in a busy or noisy place, we have a number of options available if you want top acoustics. In addition to good acoustics, energy saving is also an important consideration. Place acoustic elements on both the wall and the ceiling. Set bass trap in the corners. The output and energy spent on the acoustics always returns. A pair of corner sound absorbers also improve the acoustics a lot. Our customers can choose from many beautiful colours, from black to red. In our shop you will find all products that help you create optimal acoustics. It would take a long time to list what our shop has to offer, you will definitely find the right piece for you on our webpage. The effectiveness of the bass traps sold is also confirmed by customer reviews.
