Power Range

Power range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.

R-820F can handle a max power of 150 watts RMS from the amp the whereas R-620F has a max power handling value of 100 watts RMS, 50 watts less than the R-820F.

Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters such as Impedance, sensitivity and system efficiencies.

Input Type and Bi-Amping / Bi-Wiring

R-820F features Post type posts and R-620F has a Post type posts. None of these speakers feature bi-amping/bi-wiring.
