At most decent music stores there will be a number of pairs set up with a switching matrix to allow you to compare them side by side. Please take the time to do this.
Also carry a CD that reflects the style of music you will be doing and preferably a CD that you know well from an acoustic standpoint.
While most studio reference monitors claim to have a "flat frequency response", as you audition the pairs you will quickly discover that they all sound different. My advice is to pick a pair that are in your budget range, and that sound good to your ears and reproduce the music on your CD the best, again, according to your ears.
Most store allow a 30 or 45 day no fault return policy. With speakers this is something to be aware of and use if needed. Because the speakers may sound totally different in the home than they did in the store.
Be sure they sound like you want them or expect them to sound in the studio room. Use the reference CD you took to the store. Once you are satisfied with them at home.........
Then, learn that speaker system.
