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. You can download the native Blender file here: https://www.blendswap.com/blend/24177
