Furniture Grade Construction The cabinetry of your V6 is constructed from 34 medium density fiberboard MDF The cabinet has been specifically designed to minimize unwanted cabinet resonance All cabinet edges and port openings are heavily radiused to reduce edge diffractions and port flutter Cabinet finish is a neutral fingerprint proof gray Zolatone Custom Made Drivers KRK is renowned for using the highest performance drivers available for our products Your V6 carries on this tradition A specially designed polyvinyl LF driver was carefully selected and specifically for this cabinet volume with one goal in mind minimal compromises no surprises A proprietary silk dome tweeter was created to deliver smooth natural highs at high sound pressure levels Both of these components caused Bobby Owsinski from EQ magazine to remark The V6 has a big monitor sound in the package of a small monitor It literally has the biggest bottom I ve ever heard in a monitor of this size Troubleshooting Problem If there is no power check to see if The power cord is plugged into both the IEC socket on the rear panel of the unit and into the AC mains The AC mains voltage is matched to the operating voltage requirements See Changing Voltage in the Connecting the System section on page 3 If the AC mains voltage is higher than the V 8 s selected voltage it is possible that the fuse needs to be replaced See Changing Fuses in the Connecting the Syst
