I am trying to educate myself and understand how an equalizer affects the different speaker sound. I was listening to B&W speakers in an Audio shop and noticed a lot more detail in the mid range when compared to mine. I went home and increased the Khz to about 700 to achieve a similar level of detail. What impact does the higher number on KHz band have on the treble, mid and bass frequencies? Does it bring more details from the source? Fundamentally, how does adjusting the equalizer band affect your speaker sound?
