One of the best ways to test your speakers is to start playing music at a very high volume and then gradually lower it in steps. This will help you determine whether the imaging, depth, and soundstage (left-to-right and front-to-back) remain consistent. However, the maximum volume you can achieve depends on the room's size and acoustics. If you play too loudly in a smaller room, you risk overwhelming it, which can disrupt the soundstage. Conversely, playing too softly in a larger room may prevent you from experiencing the full impact of the music.
It’s also important to clarify what you mean by "distortion." Distortion can originate from the audio system, the room's acoustics, or a combination of both. Therefore, it’s essential to identify the source of any distortion before seeking a solution.
