Bass absorber

The purpose of the corner unit bass trap is to control the bass energy and to decrease the distortion of the bass in the studios, hi-fi and home theatre rooms.

Corner unit bass traps composition

The corner unit bass trap is filled with high density acoustic wool of 90kg/m3 which is surrounded by a heavy and dense wooden structure of 2 cm thick.
The combination of heavy weight and high density ensures the optimal bass absorption in the corners.
The corner unit bass trap functions as bass absorber the way it absorbs the random bass energy of all directions which tends to hit the corners and overload the room. And destroying thereby the acoustics of the room.
The attractive,wedge shaped, 45-degree formation allows the easy positioning in the corners.

Corner unit bass trap Placement

The bass traps are equipped with 5cm high feet in order to be able to push them into the corner even if there are parquet borders. You can order these feet in any size and it will not change the sum total. The feet of the corner units are fixed by 1 bolt thus it is easy to take it off in case you want to pile up several acoustic bass traps.

You can easily pile up the corner unit bass traps increasing thereby the bass absorption in the room. If the stacks of units do not fit the height up to the ceiling as there is no room for an additional unit, you can contact our expert who will produce it in the given size .

You only have to place the corner units in the corners without screwing or fixing them where they stand stable on their feet even if several units are piled up. Filling in the corners completely, they are perfectly appropriate in professional studios or home theatres.

Application

The bass trap can be placed even on the table if we have a smaller room or if there is a wall to wall studio table.

Piled up bass traps producing significantly higher bass absorption.

The corner unit bass trap is especially functional as it is compact therefore you can place it in almost any environment. Although there are facilities worldwide where people use the bass traps of PERFECT ACOUSTIC, these are the most efficient in smaller rooms and homes where the acoustics could be fixed later only by a significant reconstruction.

Result with the corner unit bass absorber of Perfect Acoustic.

As most of the bass is accumulated in the corners and then starting from there multiplied, they can produce huge peaks or extinctions of up to +-30dB. If you put the corner unit bass trap in the corners this accumulated bass will be absorbed or will significantly decrease thus the resulted standing waves will cease or decrease and the dips or peaks will smooth out:

acoustic measurement sound pressure value

You can see that the dip below 90Hz completely destroys the low frequency therefore we receive only dull and undynamic bass while the room growls and buzzes from the huge bass reverberation.

acoustic measurement sound pressure value

Here you can see how the sound pressure curve will be smoothed with a bass trap and the part below 90Hz comes higher and shows the details, dynamics and space in the bass. In this case also the reverberation will significantly decrease. The more corner unit bass traps you place in the room the better you can control and smooth out the lower frequencies.

The bass traps of Perfect Acoustic are not to be mistaken for poor quality materials of other companies such as light structure or maybe light density absorbing materials or foam, styrofoam.

Corner unit bass traps FAQ:

Should we put these corner units only into the corners?

Yes, due to their formation we place them specifically in the corners. We could place them elsewhere but it would look weird.

Don’t these heavy bass trap break if piled up?

It is true that it is very heavy but the absorbing material is covered by a very hard and strong wooden structure therefore we can pile up even 3 bass traps without causing any problem.

Should we mount the corner unit bass traps on the wall or how we should fix them so that they do not fall?

The bass traps of Perfect Acoustic are heavy, very rigid and they cannot fall due to their formation and size. Even if 2-3 units are piled up.

What to do if there is a parquet border in our corners thus, we cannot push the corner unit completely into the corner?

That is why we invented that each corner unit is equipped with 5cm high strong wooden feet. You can order these feet in size that fits your demand.

If the corner units are equipped with feet how can we pile them up so that it would not be visible that they are individual panels?

The feet of each bass trap are fixed with 1 thick bolt which you can remove with a phillips screwdriver in 1 minute. So, you can construct a continuous series of panels in the corner.

Why is it not sufficient if we turn across a broadband panel in the corner, wouldn’t it have the same effect?

Of course, this method is not bad, in fact it is cheaper. But from efficiency point of view it cannot produce the same sound absorbing capacity as a corner unit bass trap. Because there is signiticantly more absorbing material within the corner unit.

If I want to pile up several bass traps but there is no room because of the ceiling, could you make a smaller or even custom size unit?

Yes, of course, in such a case you just have to specify the desired height and we will produce exactly that size. In this case you mustn’t calculate it very precisely, you should order 1-2 cm shorter to avoid that you cannot fit them due to the tortuosity of the wall or the floor.

Is it possible for you to produce corner units with smaller width as well as with smaller height?

Yes, we can make it with any width but you have to note that if you order a too narrow one it will lose its effectiveness. In this case where there isn’t enough space it is advisable to order Cube bass trap in the corner because it contains double absorbing material due to its square shape thus its sound absorption capacity is doubled.

I cannot decide which sound absorber to place into the room first. The broadband or the corner unit?

It depends on a lot of factors. If you have problems with the bass as the majority does then you should start with the bass trap. If you only want to dampen the echo such as in the office, living room or workplace you should use a type of broadband acoustic panel.

Is the type of cover relevant also for the bass traps? Does it make sense to use diffuser face plate or membrane also in this case?

Yes, of course. It depends a lot on the acoustics of the room but if you wish e.g. a diffuser face plate on the bass trap for decoration purpose you will not do wrong, moreover, the diffuser face plate will even more increase its efficiency. Or you can decorate it with any photos, you can choose from our website or bring your own photos as well.

If you feel your room to be slightly dull but rumbling then it would be advisable to consider wooden membrane or leather membrane.

What kind of sounding can I expect if I place it in my room?

The bass will be captured immediately. The more units you put into the room the calmer the space will be, the rumbling of the low frequencies will cease, the details in the low frequencies will emerge, the high frequencies will be much cleaner and with more sense of space because the significantly more basses that existed so far do not repress them, therefore you will feel a huge benefit in the details. As the needless bass reverberation disappears we can increase the volume without the sound being offensive or disturbing.

Can I use the bass trap for sound proofing?

These products are not suitable for sound proofing. Other sort of structural design must be performed in the room for this purpose. But if you wish that your neighbours or your family hear the music less loud it will be perfectly fit for this purpose. As it has high sound absorbing capacity in the full bandwidth, mainly in the lower frequencies, therefore by absorbing the sound it can achieve a volume decrease of up to 15-20dB in the other room.

Isn’t the sound absorbing material within the corner unit bass trap harmful to health? Can it get out from the acoustic panel?

We use acoustic wool developed especially for this purpose which is absolutely harmless for the health, not only for the bass traps but also for each of our sound absorbing acoustic panels. In order to eliminate the risk of this dust emission each of our acoustic panel contains a dust emission inhibitor and in addition we use high density acoustic velvet the gaps of which barely let the sunshine through.
