This is a 3D model created in blender, and the main modifiers that are in the modifiers panel are subdivisional surface with values of 2 and 3.
All the parts are detachable as shown in the preview images.
** What you see is what you get **
--> This scene consists of a good quality speaker with very high polygon count but with applied subdivisional surface modifers on almost all the components so you can easily turn the modifiers off anytime to get the low poly version.
--> All the textures are procedural and no image is used whatsoever and I made the model myself after looking at few reference images and combining them and my knowledge into one model.The original picture is on dropshipstrategy's products, speaker page I believe floor speakers. But they are 2 separate speakers and I have just used them as a reference.
--> It also contains a simple floor and a room with a very basic wall and no textures.
