In this review, we will be comparing UFR52 and R700, two Passive Floor-standing speakers from ELAC and Polk Audio. Let's have a brief look at the main features
of ELAC Uni-Fi Ref UFR52 and Polk R700 first before getting into our more
detailed comparison.
What size room are the ELAC Uni-Fi Ref UFR52 and Polk R700 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the ELAC Uni-Fi Ref UFR52 and Polk R700 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

UFR52 features a 1" soft dome Tweeter , a 4" Midrange and 3 x 5.25" Aluminum Woofer . On the other hand, the R700 features a 1" Pinnacle Ring Radiator Tweeter , a 6.5" Midrange and 2 x 8" Polypropylene Woofer with a Crossover frequency at 350Hz and 2700Hz.
Frequency Response
UFR52 has a frequency range of 40-35k Hz whereas R700 has a frequency range of 38-38k Hz. With a minimum frequency of 38Hz, the R700 can go slightly deeper then the UFR52's min frequency of 40Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Floor-standing class in our database.

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
UFR52 is a 6 ohms speaker compared to the R700 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. UFR52 sensitivity is rated at 86 dB and the R700's is rated at 88 dB. This 2 dB difference makes the Polk R700 a more sensitive speaker compared to ELAC Uni-Fi Ref UFR52, 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.
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.

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 UFR52's and Polk R700's external dimensions. 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) whereas Polk R700 has external dimensions of 1143.8 x 320.7 x 428.3mm ( 45 x 12.6 x 16.9inch) .
Polk R700 is clearly the larger of the two speakers. Its body is 85.7mm wider, 138.8mm taller and 89.3mm deeper than ELAC Uni-Fi Ref UFR52.
Below you can see the front view size comparison of ELAC Uni-Fi Ref UFR52 and Polk R700 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 UFR52 is approximately 796.7cm2 / 123.5inch2 and base area of the Polk R700 is approximately 1373.6cm2 / 212.9inch2. The UFR52 requires 42% less surface area than the R700 which gives it a small advantage on placement in tight spaces.
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 UFR52 weighs 23.80kg / 52.4lbs and the Polk R700 weighs 35.90kg / 79lbs. This makes the R700 51% heavier than the UFR52.
Here is a comparison of how UFR52 and R700's weights compare with the average, max and min weights in Passive Floor-standing class.
