High Frequency
Bookshelf Speakers
None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
UBR62 and UFR52 have the same Impedance of 6 ohms but where they differ is the sensitivity levels. UBR62 sensitivity is rated at 85 dB and the UFR52's is at 86 dB. This 1 dB difference makes the ELAC Uni-Fi Ref UFR52 a more sensitive speaker compared to ELAC Uni-Fi Ref UBR62, hence will play louder with the same amount of watts.

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.
UBR62 and UFR52 has the same power range of up to 140 watts.
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 UBR62 and UFR52 features dual binding post speaker terminals for bi-amping or bi-wiring.
