BASSER speaker rings are manufactured in Poland, entirely from products originating from the European Union. We use high-quality PETG material for their production, known for its durability and resistance to weather conditions. Additionally, it has on average 25% higher density than MDF.

PETG adapters guarantee stable mounting and, thanks to their rigidity, ensure excellent speaker sound. PETG material is naturally water-resistant, which eliminates the need for additional waterproofing. The adapters are available in black color, which effectively masks them and makes them invisible through speaker grilles.

Before mounting speaker in the adapter, holes for screws should be drilled using an appropriately selected drill bit.
