Between the volume adjust and several out put ports for RCA and the regular quarter inch output as well as the volume adjust knob are what makes this Monitor along with the good range of frequency this thing puts out

This allowed me to have a greater working range on volume.

They produce clean and incredible full range sound, they amaze me for their size

By contrast, "loudspeakers" are used for home audio and they typically have boosted bass and or treble response (low and high frequencies) to make the sound more punchy and colorful, especially since nearly all consumer audio sources come from highly compressed MP3 sources where much of the dynamic range of the original music track has been lost

The flat tone and frequency range is just awesome

The sound is excellent, and the range was much better than I anticipated, especially the low end
