Studio Monitors:  You will find Passive,Active Studio Monitors and even subwoofers in this section.  A good set of studio monitors is key to any set up.  And finding the right pair or single (mono) can be a tough decision.  It is based off of your room (acoustics, size etc...) and the type of music content you are primarily recording and mixing.  Maybe you need a subwoofer or maybe a set of full-range monitors will do the trick.  I am here to help you narrow down that decision.
