The role of bass traps:

Acoustic treatment is an essential task. In a home studio, the best solution for studio work is to use a deep sound absorber.
For clear sound and excellent acoustics, a bass or membrane bass trap, a polar bass absorber, is essential. With their help, we can perform the main and at the same time the most difficult task during acoustic treatment: isolating the bass.

Why is necessary the isolation of bass?

For bass below 150 Hz, the reflection of the sound wave from the surface to the space increases. In practice, this means that we do not hear the true quantity and quality of the low frequencies, but the sound of the room. Distorted bass can damage the sound experience, in the case of a studio the audio recording, so it is absolutely necessary to improve the acoustics of the room. We work with the best wood material, when we build the bass traps. The corner bass traps are designed for the corner, so they can be placed very simply in any corner. These types of the acoustic panels can control the sound energy and help the create the best acoustics in a home studio or audio recording studio.

How can membrane and corner bass traps help in the acoustics treatment?

Membrane and corner bass traps are primarily used to suppress echo and standing wave.
The bass trap and the corner bass absorber are acoustic elements that reduce excessive sound wave in a narrower frequency range. Unlike other absorbing acoustic panels – broadband acoustic panels cannot effectively attenuate bass frequencies – membrane bass traps absorb bass significantly more efficiently in the low frequency range. The most problematic area is the corner, as it is where most of the deep sounds gather. Without handling the acoustics, the sound wave is reflected back into the space from the smooth, hard wall surface, creating an unpleasant echo. The best solution to an acoustic problem in a corner is to use a corner bass absorber. In the studio, we need to control sound energy if we want the best results.

Designed for sound insulation and absorption, acoustic elements are made of high quality material with their thickness to insulate at low frequencies. They are made of real wood and contain acoustic wool, which also has excellent sound insulation properties. Thanks to the careful finish and precise fit, after proper acoustic measurement and precise adjustment, we can get a cleaner, more airy, more lifelike and more pleasant acoustics at home, or in a home studio.

Many people think that buying the best quality, top price studio monitors and standing speakers for your studio is enough for optimal acoustics.
However, this is not the case. Even with the best audio equipment, speakers cannot provide the best performance if the acoustics are poor. The AV-receivers have room calibration softver, but these programs can control the sound pressure mainly, but these audio devices can’t eliminate the echo of the space. In an audio studio, the proper placement of the studio monitors and the speaker is also very important as it largely determines the sound. Properly tuned speakers, optimal sound pressure, and flawless acoustics work together for the best results.Our corner bass traps are designed for the improvement of the acoustics in any room, studio or home cinema.

Why is foam, acoustic foam, polystyrene not effective in improving room acoustics and in insulation of deep sound?

The length of bass sound waves is longer than the length of the high frequencies. The insulation of bass we need acoustic panels made of other types of materials on the walls, and a corner bass traps in the corner. Deep basses can only be tamed by dense, fibrous, high-density material or an acoustic membrane, such as real wood and acoustic wool lining content. When we build a studio, we often make the mistake of completely gluing the walls with acoustic foams, but the effect is well below their expectations and, on the contrary, the soft, lightweight foam, polystyrene, acoustic foam absorbs the higher frequencies, so the low frequencies are more dominant, which was originally intended to attenuate. Skip cheap sponge and foam panels that are not suitable for deep sound isolation, as these types of panels are not effective at all. In addition, they can only be attached to the wall surface with glue, and the glue cannot be completely removed from the wall surface. Don’t waste your energy and money on such useless products. The wood absorber can be simply placed on the wall or in the corner.

How to use membrane bass traps and the corner bass absorber?

  • Basses should be muted first in the corner, then on the side walls – especially the front wall – and behind the listening area.
  • If possible, do not place bass traps directly against the wall, keep a distance of at least 10 cm.
  • We must not forget one of the most important parts of the room, the ceiling.
    Because this area is empty, the standing wave can propagate without obstruction, causing large peaks and zeros at low frequencies.

Where can we use bass traps?

  • The bass absorber can be used in the studio,home or audio studio, home theater, living room to improve acoustics.
  • In cases where other absorber panels do not provide sufficient attenuation at low frequencies.
  • In places where high frequencies are already over-attenuated against low frequencies.
If you can only buy one thing, you have to choose this!

To achieve excellent acoustics, we need to install multiple panels. If the characteristics of the room do not allow the placement of the right amount of acoustic panels, it is essential to use a membrane bass trap even in such cases, corner handling is one of the main tasks!

The bass trap has the following benefits:

  • A clearer, smoother, more lifelike sound.
  • Best bass attenuation, the room fills with real bass music or movie.
  • Decorative accessory in the living room or studio.
  • In addition to creating the best sound, we also pay special attention to the look. We use top quality materials — wood, leather, imitation leather, acoustic velvet, cotton, wool — and we also implement custom ideas — our own photo, printed design, custom size.

Why are membrane subwoofer traps made by Perfect Acoustic the best options?

Made with expertise and experience

In addition to our high level of professional expertise, we also use the learn of previous years in the design and manufacture of our products.
The maximum efficiency produced by our unique technology, our bass traps can be proud to have the highest sound absorption and insulation coefficient available on the market.

Wonderful design and built

When manufacturing our special, deep-based, membrane bass traps, we pay special attention to both their acoustic efficiency and their aesthetic appearance. In addition to the materials we design and use, it is important that our products match the style of your studio, living room or home theater.

Practical placement, simply setup, effective work

In addition to acoustic efficiency and aesthetic appearance, we also strive for practical placement. Due to their size and weight, our bass traps can not only be mounted on a wall, but can also stand on their own and be stable in the corner.
Thus, they can also be used as mobile panels.
Our panels were supplied with drills with screws to facilitate wall or ceiling mounting.

What types of materials do we use for build?

Depending on the types bass trap can be made of wood or imitation of leather. The biggest problem is the dampening of low frequencies below 70 Hz since fibrous, absorbing materials are not appropriate.
However resonating membrane bass trap sheets made of wood or leather can tame unwanted low frequency sound wave up from 30 Hz.
Wood membranes work between 30Hz and 200Hz, imitation of leather membranes mitigates between 30Hz and 600Hz.

Appearance of our products

Besides effectiveness we pay a special attention also to the appearance, offering wide range of designs:

  • Acoustic velvet/silk in 16 different colours
  • Imitation of leather in various colours and texture.
  • Optional printed designs from our stock
  • Own photo option
  • Custom made sizes
  • Designing hidden absorber

Importance of material use:

Effective bass absorption requires the right raw materials. Acoustically ideal materials have a flexible, perforated or porous structure and a high bulk density. Such materials include the hardwoods we use, plywood, laminated furniture board, acoustic wool, and textiles designed for acoustic purposes. In addition to its anti-dust properties, acoustic silk is a flexible, durable fabric, as is acoustic imitation leather. Cellular materials, such as styrofoam, are not suitable for either sound absorption or sound insulation.

We can’t completely eliminate bass!

Bass sounds are needed for the best and most harmonious sound, for proper acoustics, but you definitely need to manage the bass range so as not to spoil the sound experience. Let’s start with the corner. It is advisable to adjust the amount of bass absorber to the size and shape of the room. The most problematic in this respect are the smaller, square or rectangular rooms, as the proximity of the walls amplifies the echoes. It is a good idea to seek expert advice on exactly how many sound-absorbing panels are needed and where they are recommended to be placed. Excessive attenuation can be avoided as the goal is not to create a so-called “deaf room”. Acoustic measurements can be used to determine exactly where, what and how many acoustic elements to place.
Thanks to the wide range of colours and patterns, as well as the size, our acoustic sound-absorbing panels also stand out as a decorative interior design element. You will find several excellent absorbent types in our online shop. You can also find a detailed description of the product on the products page. If you need help, email us.
