Our matte sandblasted aluminum speaker tube is a premium custom round aluminum sound box case, widely used as red anodized extruded aluminum audio enclosure and cnc machined aluminum bluetooth speaker housing.
Manufacturing starts with seamless 6063 aluminum round tube extrusion, followed by fixed-length saw cutting. Multi-process CNC machining includes turning for flat end trimming and inner/outer wall fine finishing, plus milling for side key slot, internal positioning buckles and external vertical heat dissipation ribs. After full deburring and ultrasonic oil residue cleaning, uniform fine matte sandblasting is applied, then hard rose red anodizing for scratch resistance and premium metallic texture.
As a professional CNC OEM manufacturer, we provide full custom service for all audio housings, adjustable dimensions, rib layout, slot position and anodized color, with strict dimensional tolerance to ensure perfect matching with speaker circuit boards, batteries and speaker units.
