The shells of AK 3+4 are made from PET felt, a durable material produced from recycled plastic bottles. Soft to touch, strong in use, with natural sound-absorbing properties. A honeycomb paper core filling reinforces the panels and enhances acoustic performance. Both recycled and recyclable, the few components make AK 3+4 easy to disassemble after a long lifespan.
