Welcome to our store！</br> 1、Rubber, Paper: Speaker cone drum paper is made of high grade rubber and paper, which is tough and durable, abrasion and scratch resistant, and has a long service life. 2、Sealing Edges: The sealing rounded edges of speaker cone drum paper are strong enough to resist scratching and stretching, blocking dirt and protecting the coils. 3、Function: The speaker cone with rubber surround (diaphragm) is the front part of the speaker. As the coil moves back and forth, the driving cone vibrates like a drum skin, emitting sound and entering the air. 4、Superior Performance: The rolled cone has a smoother high frequency roll off, but the cone can absorb moisture from the air, which changes its mass and damping characteristics. 5、Specification: The outer diameter is 156mm/6.14in; the inner diameter is 26mm/1.02in; the height is 30mm/1.18in; the standard specification and size, easy to install. <p class="wang-edit-text"><p class="wang-edit-text"><p class="wang-edit-text"> Item Type:&nbsp;Speaker&nbsp;Cone&nbsp;Drum&nbsp;Paper Material: Rubber, Paper Size: Outer Diameter: Approx. 156mm/6.14in Inner Diameter: Approx. 26mm/1.02in Height: Approx. 30mm/1.18in <style> .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }</style> 2 x Speaker&nbsp;Cone&nbsp;Drum&nbsp;Paper&nbsp;&nbsp;&nbsp;2 x Paper Hat Satisfaction - Our customers are our top priority.
