VocoPro asked their customers for feedback on the shortcomings of the Karaoke hardware industry and were told that a major issue was the absence of quality Karaoke speakers designed specifically for vocals. VocoPro was told most all Hi-Fi and PA speakers out there were either too bottom heavy lacking in midrange, or too hyperactive with excessive treble response leading to annoying feedback. To resolve this problem, VocoPro proudly introduced the SV Series Karaoke Vocal Speakers!
