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.

UFR52 can handle a max power of 300 watts RMS from the amp the whereas UFR52 has a max power handling value of 140 watts RMS , 160 watts less than the R700.

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

Both UFR52 and R700 features dual binding post speaker terminals for bi-amping or bi-wiring.
