Fiber reinforced ultra-stiff paper composite cone

For the build quality, the cone is made out of a fiber reinforced ultra-stiff paper composite cone. Whereas most subs will have a paper cone alone for the cone, the fiber-cone composite on this one observes both rigidity and lightweight which are the two key features on any cone that’s ideal for a good bass

Still, at the cone, it is worth pointing out that it's got a dust cap added to it which simply adds on to the durability of the subwoofer.

An accordion cloth surround.

Besides just having a good cone, the surround is also quite commendable. Though it’s not the best, the accordion cloth surround should be able to deliver a reasonable level of flexibility and in the long run pump out a good bass
