Ultra Tower features a 1.0" aluminum Dome Tweeter , a 6.5" Midrange and 2 x 8.0" Polypropylene Woofer with a Crossover frequency at 160HZ and 2000Hz. On the other hand, the UFR52 features a 1" soft dome Tweeter , a 4" Midrange and 3 x 5.25" Aluminum Woofer .
Frequency Response
Ultra Tower has a frequency range of 28-32k Hz whereas UFR52 has a frequency range of 40-35k Hz. With a minimum frequency of 28Hz, the Ultra Tower can go significantly deeper on the low side and provide stronger bass compared to 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
Ultra Tower is a 8 ohms speaker compared to the UFR52 which has a nominal impedance of 6 ohms.
These two speakers also have different sensitivity levels. Ultra Tower sensitivity is rated at 88 dB and the UFR52's is rated at 86 dB. This 2 dB difference makes the SVS Ultra Tower 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.
Ultra Tower 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 Ultra Tower.
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 Ultra Tower and UFR52 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 SVS Ultra Tower's and ELAC Uni-Fi Ref UFR52's external dimensions. SVS Ultra Tower has external dimensions of 1159.0 x 355.0 x 445.0mm ( 45-5/8 x 13-15/16 x 17-1/2inch) 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) .
SVS Ultra Tower is clearly the larger of the two speakers. Its body is 120mm wider, 154mm taller and 106mm deeper than ELAC Uni-Fi Ref UFR52.
Below you can see the front view size comparison of SVS Ultra Tower and ELAC Uni-Fi Ref UFR52 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 SVS Ultra Tower is approximately 1579.8cm2 / 244.9inch2 and base area of the ELAC Uni-Fi Ref UFR52 is approximately 796.7cm2 / 123.5inch2. The Ultra Tower requires 98% more surface area than the UFR52 which gives it a small disadvantage on placement in tight spaces.
