The STAIDTREAT BXA is a low-frequency absorption panel. The STAIDTREAT BXA is a low-frequency absorption panel. It is tuned to 63 Hz and is meant to be placed in 90° corners. The principle used to develop the STAIDTREAT BXA is exclusive to JOCAVI. It combines an ABS box, which has two appropriately enhanced closed resonance chambers inside, with mass and density components. These components have been specifically developed for this model. Therefore, because of its careful development, this panel has become one of the best offers in the market for low-frequency absorbent materials. In order to boost bass absorption, we recommend that this panel is used together with the STAIDTREAT BXW, as the latter functions close to the harmonics of this model.
