UBR62 features a 1" soft dome Tweeter, a 4" Midrange and 1 x 6.5" Aluminum Woofer. On the other hand, the UFR52 features a 1" soft dome Tweeter, a 4" Midrange and 3 x 5.25" Aluminum Woofer.
Frequency Response
UBR62 has a frequency range of 41-35k Hz whereas UFR52 has a frequency range of 40-35k Hz. With a minimum frequency of 40Hz, the UFR52 can go slightly deeper then the UBR62's min frequency of 41Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
UBR62 and UFR52 have the same power range of up to 140 watts.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Both UBR62 and UFR52 features dual binding post speaker terminals for bi-amping or bi-wiring.

Physical Specs
The size of a speaker can sometimes be 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 Ref UFR52'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 Ref UFR52 has external dimensions of 1005.0 x 235.0 x 339.0mm (39-9/16 x 9-1/4 x 13-5/16inch).
ELAC Uni-Fi Ref UFR52 is clearly the larger of the two speakers. Its body is 25mm wider, 646mm taller and 7mm deeper than ELAC Uni-Fi Ref UBR62.
Below you can see the front view size comparison of ELAC Uni-Fi Ref UBR62 and ELAC Uni-Fi Ref UFR52 in scale.
