Limp Bear

Lightweight broadband absorption panel of limp bag type. With a generous amount of Limp Bear panels in your room, low and mid frequency decay times can be greatly reduced when placed right.

 

Product information:

This sound absorption panel is a great room acoustic device for reducing decay times (commonly called Reverberation) in the low and mid frequencies. It's most effective around approximately 100-2000 Hz but this can be somewhat altered when using different depths. The surface around the panel is highly reflective at primarily high frequencies. This reflective and limp surface acts as a limp membrane and together with the mass inside, this air tight enclosure and acoustic system efficiently reduces acoustic energy and lowers the decay times. In contrast to a velocity type broadband porous absorber as the Absorbear, these Limp Bear panels do not need to be as deep in order to reduce lower frequencies. Limp Bear panels are relatively shallow (10 or 15 cm deep), which makes them easy to move and to place. Also, they are relatively affordable even though a generous amount of panels often is needed to get satisfactory results.

The Limp Bear panels suits different room acoustically challenging scenarios such as:

* Any audio listering room with absent or insufficient low frequency management
* Any room with excessive MF and LF decay times and modal ringing issues

Limp Bear XL:
We also offer an XL sized Limp Bear panel, which has 1,5 times the mass compared to the Limp Bear. It is therefore even more effective and especially at lower frequencies.

Absorption ability details:

Lab testing results with absorption coefficients and quantifiable details can not be presented at this moment, due to it's high costs. In order to properly lab test our products in a suitable (and big enough) reverberation lab environment with high accuracy in low frequencies, it would require a big sum of money. With that said, Ljudbjörnen has planned to carry through such lab tests of all offered products further on.

Materials:

Polyester absorption panel
Plastic cover

Mounting options:

In order to optimize the absorption performance, the placement of the Limp Bear panels is critical. To maximize the performance and making sure these Limp Bear panels reduces the energy of the mode(s) or frequency regions you are intending to reduce, make sure you ask for a proper installation.

If additional mounting solutions are requested, such installation can be executed on request.

Size:

Limp Bear measures: 120 X 62 X 10 cm
Limp Bear XL measures: 120 X 62 X 15 cm

+/- 2 cm for the width and length due to a high difference tolerance at the absorption factory.
