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.
kO-R2 can handle a max power of 1200 watts RMS from the amp the whereas kO-R2 has a max power handling value of 300 watts RMS , 900 watts less than the Jubilee.
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
kO-R2 features Binding post type posts and Jubilee has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both kO-R2 and Jubilee have front firing ports. front ported speakers offers more flexibility in placement in regards to proximity to walls&surfaces compared to rear ported speakers.
