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.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing 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
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.
Sensitivity
Floor-standing Speakers
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.
Ultra Tower can handle a max power of 300 watts RMS, whereas UFR52 has a max power handling value of 140 watts RMS, 160 watts less than the Ultra Tower.
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.

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 Ultra Tower 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 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.
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 SVS Ultra Tower weighs 34.27kg / 75.4lbs and the ELAC Uni-Fi Ref UFR52 weighs 23.80kg / 52.4lbs. This makes the Ultra Tower 44% heavier than the UFR52.
Here is a comparison of how Ultra Tower and UFR52's weights compare with the average, max and min weights in Passive Floor-standing class.

A generation apart: ELAC Uni-Fi Ref UFR52 is the newer design, against a 2013 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | A | SVS Ultra Tower digs deeper - 28Hz against 40Hz. |
| Amplifier needs | A | SVS Ultra Tower is more sensitive (88dB vs 86dB), so it goes louder on the same amplifier. |
| Amplifier match | A | SVS Ultra Tower is the easier load at 8 ohms. |
| Headroom | A | SVS Ultra Tower takes more power (300W vs 140W) - more in hand in a big room. |
| Size | depends | ELAC Uni-Fi Ref UFR52 is easier to place; SVS Ultra Tower is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | SVS Ultra Tower: bi-amping; ELAC Uni-Fi Ref UFR52: bi-amping. |
| Price | evenly matched | Much the same money ($2,600 vs $2,400 a pair). |
A SVS Ultra Tower B ELAC Uni-Fi Ref UFR52
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
SVS Ultra Tower has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 40Hz anyway, so judge these on the other rows instead. Match it to your room: we rate SVS Ultra Tower the better fit for a very large room, and ELAC Uni-Fi Ref UFR52 for a mid-size room.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
