Here from our 3D audio line are a set of 10" Subwoofer backs.
These were designed to lay flat and only show the rear part of the sub. Work well with any custom idea you might have for your project.
 
This is for a set of 4!
 
PLEASE NOTE: 
1. Print colors will vary from what is pictured, as we sometimes print multiple items; resin colors will vary on what you receive. 
 
2. Many 3d prints do not have a smooth finish as larger prints will have some ridges. Light sanding and primer helps to remove any print lines.
