It gives the speaker a closed 15-liter enclosure lined with acoustic damping wool, which keeps sound from leaking into the room next door.

Its 15-liter internal volume matches what AUDAC recommends for the open-back CELO and MERO series, so low-frequency response holds up. The steel shell meets fire-rated ceiling requirements, and the damping wool absorbs back-wave energy. Use it in offices, hotel rooms and meeting rooms where sound isolation or fire code applies.
