Acoustic Treatment
When you listen to music or anything else on speakers, the sound reverberates throughout the room. All rooms have a degree of echo that affect the sound. As a result, regardless of the quality of your speakers, there will be a slight echo that affects the sound.
However, if you purchase acoustic treatment to coat your room, you will get much better audio. The best example is a pack of foam squares you can line your walls with. Doing so will dampen the natural echo in your home recording studio.
