KRK Classic 5 studio monitors.
I created these speakers in Blender, Blueprints weren't available so I used reference images I got from the product website http://www.krksys.com/Classic
This model is downloadable and you are free to use this model as you like but be aware it is a real product owned and copyrighted by KRK Systems, so you will need to do some research before using it on your specific project.
