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.
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
UBR62 features Binding post posts which make bi-amping or bi-wiring possible. Uni-Fi 2.0 UB52 has a 5-way post which doesn't feature bi-amping/bi-wiring.
Physical Specs
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare ELAC Uni-Fi Ref UBR62's and ELAC Uni-Fi 2.0 UB52's external dimensions. ELAC Uni-Fi Ref UBR62 has external dimensions of 359.0 x 210.0 x 332.0mm ( 14-1/8 x 8-1/4 x 13-1/16inch) whereas ELAC Uni-Fi 2.0 UB52 has external dimensions of 347.0 x 186.0 x 297.0mm ( 13-5/8 x 7-5/16 x 11-11/16inch) .
ELAC Uni-Fi Ref UBR62 is clearly the larger of the two speakers. Its body is 24mm wider, 12mm taller and 35mm deeper than ELAC Uni-Fi 2.0 UB52.
Below you can see the front view size comparison of ELAC Uni-Fi Ref UBR62 and ELAC Uni-Fi 2.0 UB52 in scale.
Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the ELAC Uni-Fi Ref UBR62 is approximately 697.2cm2 / 108.1inch2 and base area of the ELAC Uni-Fi 2.0 UB52 is approximately 552.4cm2 / 85.6inch2. The UBR62 requires 26% more surface area than the Uni-Fi 2.0 UB52 which gives it a small disadvantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The ELAC Uni-Fi Ref UBR62 weighs 10.70kg / 23.5lbs and the ELAC Uni-Fi 2.0 UB52 weighs 8.30kg / 18.3lbs. This makes the UBR62 29% heavier than the Uni-Fi 2.0 UB52.
Here is a comparison of how UBR62 and Uni-Fi 2.0 UB52's weights compare with the average, max and min weights in Passive Bookshelf class.
