Function:
SIZE SPECIFICATIONS: Outer diameter of speaker cone drum paper is 75mm, inner diameter is 20mm, height is 16mm, size is accurate.
PREMIUM MATERIAL: The paper speaker drum is made of premium paper. The sealed round edges are strong enough to withstand scratches and stretch and block dirt and protect the coil.
Working principle: Speaker cones with rubber surround (diaphragm) on the front of the speaker. When the coil moves back and forth, the driving cone vibrates like a drum skin and makes a sound and penetrates into the air.
IMPROVED PERFORMANCE: Paper speaker cones are smoother to roll off high frequency but paper cones can absorb moisture in the air, which changes the mass and attenuation characteristics.
Application: 3" speaker subwoofer cone drum paper with 2 paper covers, after installation, easy to install, no complicated procedures or tools required.
