I've had these Behringer truth b1030a's for a while now and I just noticed an issue. I was listening to: The Strokes - Heart In A Cage - YouTube I remembered there used to be a guitar riff at the beginning of the song...I cannot hear it at all, only the drum and bassline. I played the track on my phone and could hear it. What is wrong with my studio monitors, any way to fix this? I'm kind of new to mixing/mastering also. This is kind of a big deal if I get into mastering. Thanks!
