PSI Audio AVAA C20 White

The revolutionary solution for room mode problems. The PSI AVAA C20 is the result of years of research offering a compact, efficient solution for room mode problems between 15 – 150Hz. It will function just like passive absorbers but in a much more efficient way using considerably less space. The AVAA works independently from any source of sound and requires no measurements or settings to be applied. Simply place them in the corners of your room, turn them on and experience more accurate imaging in the low end.

Product Description

The revolutionary solution for room mode problems. The PSI Audio AVAA C20 is the result of years of research offering a compact, efficient solution for room mode problems between 15 – 150Hz. It will function just like passive absorbers but in a much more efficient way using considerably less space. The AVAA (Active Velocity Acoustic Absorber) works independently from any source of sound and requires no measurements or settings to be applied. Simply place them in the corners of your room, turn them on and experience more accurate imaging in the low end. 

The AVAA’s are available in four colours, please put in an enquiry to sales@emerginguk.com if you are interested in the two tone colours.

Their complete analogue design enables them to function like any other acoustical element in your room and can be turned on and off via a simple switch. The AVAA is effective in a wide range of spaces, including control rooms, live rooms, listening rooms and any rooms with low-frequency problems. It works independently from any sound source without altering it and doesn’t emit any sound, making it perfect for use in critical listening and recording environments. 

The AVAA will have the same effect, on frequencies from 15 to 150 Hz, as opening a window about 5 to 10 times the size of the AVAA. This will impact sound in the time, frequency and space dimensions.

  • Time: it will significantly reduce reverberation time in these frequencies especially on room modes. 
  • Frequency: with more precise and tighter bass, the masking effect of higher frequencies is reduced. Details in higher frequencies also become clearer. 
  • Space: with less indirect sound in the room, the location of the sound is more accurate making the sound image more precise.

The PSI Audio AVAA C20 offers the same low-end absorption as a bass trap more than 10 times its size. 

How does it work? 

The AVAA’s internal microphone measures the acoustic pressure in front of an acoustic resistance. The acoustic resistance is designed to let air through, but significantly reduce the pressure. A transducer membrane is driven to absorb the volume of air going through the acoustic resistance. This significantly reduces the acoustic pressure (between 15 and 150 Hz) around the microphone and around the AVAA. 

How many AVAAs do I need? 

Depending on the size of the room between 2 and 8 AVAAs are necessary. For small rooms a minimum of two AVAAs is recommended to have a symmetrical effect. For most normal size rooms (between 20 and 80 m2) it is recommended to use 4 AVAAs and for larger rooms the number can be increased to 6 or 8.
