This is how you get your speakers to give you honest flat response with proper EQ based on real information. Plug in a test mic (not included) send the pink noise through your speakers, adjust the EQ until the lights are all in a line on the middle row. Easy. Your speakers will sound WAY better, because they are adjusted properly for the room.
Note: all the lights work---some are not seen lighting up in the pic because of the shutter speed.
