Benefits of the 21″ 535-775 aluminium die-cast speaker baskets
“MATERIAL: Our 21″die-cast cone frames P535-775 are made of high quality aluminium, offering the advantages of high strength and light weight.
PRODUCT CONSTRUCTION: The die casting process is used to inject molten aluminium into the die casting mould under high pressure in a die casting machine. It is capable of producing aluminium alloy frames with precise and consistent dimensions.
Dimensions: Our 21 aluminium die-cast speaker baskets can accommodate up to 21″ speaker cones and can be securely mounted and positioned.
Mounting holes: Our aluminium cone frames have fixed mounting holes for easy mounting of the speaker cone frame to the speaker cabinet.
Rigidity and resonance damping: die-cast aluminium alloy construction reduces unwanted vibration and resonance, helping to improve sound quality.
Heat Dissipation: Die-cast aluminium alloy has good thermal conductivity, and the21 aluminium die-cast speaker baskets can effectively dissipate the heat generated by the speaker components.
CORROSION RESISTANCE: Our speaker frames have a layer of powder coating on the surface, which can well resist external corrosion, making the speakers suitable for a variety of environments.”
