Sound absorbing system
Slotbar is a modular sound-absorbing system developed by Architected Sound. Uniquely arranged natural wooden bars absorb low tone resonance. Its properties result from specifically designed slot system which maintains optimum acoustic conditions and provides innovative shape. The whole structure guarantees absorption in low frequency range. SlotBar can be used as standalone system or in addition to OptiDi.
Simplicity is the key to brilliance!

Details
SlotBar properties allow the absorption of sound in the low frequency range with relatively small thickness of the structure, which is particularly desirable in small sized studio rooms. It is possible to precisely design the range of sound absorption in the low frequencies due to specially developed slot system with a variable gap width, supported by the use of acoustic nonwovens and an invisible layer of material with appropriately selected acoustic properties. Optional installation of teletechnical, electrical equipment and executive modules inside the system.
