help needed. is this sentence correct?

[everlidmiri]

Hello everyone, 

 

I am trying to do a little website translation thing for my dear friend. 

Could anyone help me with this sentence? I am not quite sure if it is correct (for sure not). It is about loudspeakers.

 

xzt company 使用很复杂的坚硬和内部隔板的几何的多层胶合外壳。

 

it is giving me a headache. I want to write something like "xyz uses multi-layered glued enclosures (cover), with very complicated geometry of partitions and internal stiffening."

 

Any help would be greatly appreciated
