Prime Tower features a 1" aluminum dome Tweeter, a 4.5" Midrange and 2 x 6.5" Polypropylene Woofer with a Crossover frequency at 350Hz and 2100Hz. On the other hand, the DFR52 features a 1" cloth dome Tweeter, a 5.25" Midrange and 2 x 5.25" Aramid fiber Woofer.
Frequency Response
Prime Tower has a frequency range of 30-25k Hz whereas DFR52 has a frequency range of 42-35k Hz. With a minimum frequency of 30Hz, the Prime Tower can go significantly deeper on the low side and provide stronger bass compared to the DFR52's min frequency of 42Hz.
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
Prime Tower is a 8 ohms speaker compared to the DFR52 which has a nominal impedance of 6 ohms.
On the other hand, they have the same sensitivity of 87 dBdB.
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.
Prime Tower can handle a max power of 250 watts RMS, whereas DFR52 has a max power handling value of 140 watts RMS, 110 watts less than the Prime 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
Prime Tower features 5-Way post type posts and DFR52 has a 5-Way post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Prime Tower and DFR52 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 Prime Tower's and ELAC Debut Ref DFR52's external dimensions. SVS Prime Tower has external dimensions of 931.0 x 204.0 x 297.0mm (36-5/8 x 8 x 11-11/16inch) whereas ELAC Debut Ref DFR52 has external dimensions of 1031.0 x 232.0 x 283.0mm (40-9/16 x 9-1/8 x 11-1/8inch).
SVS Prime Tower is 28mm narrower and 100mm shorter than ELAC Debut Ref DFR52 but it is also 14mm deeper.

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 Prime Tower is approximately 605.9cm2 / 93.9inch2 and base area of the ELAC Debut Ref DFR52 is approximately 656.6cm2 / 101.8inch2. The Prime Tower requires 8% less surface area than the DFR52 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 SVS Prime Tower weighs 18.23kg / 40.1lbs and the ELAC Debut Ref DFR52 weighs 16.77kg / 36.9lbs. This makes the Prime Tower 9% heavier than the DFR52.

A generation apart: ELAC Debut Ref DFR52 is the newer design, against a 2015 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 Prime Tower digs deeper - 30Hz against 42Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (87dB vs 87dB) - both want much the same power. |
| Amplifier match | A | SVS Prime Tower is the easier load at 8 ohms. |
| Headroom | A | SVS Prime Tower takes more power (250W vs 140W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | Neither adds bi-amping, a sub output or height drivers. SVS Prime Tower sits in a wider range (8 models), so a matched surround system is easier later. |
| Price | evenly matched | Much the same money ($1,400 vs $1,400 a pair). |
A SVS Prime Tower B ELAC Debut Ref DFR52
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 Prime 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 42Hz anyway, so judge these on the other rows instead. Match it to your room: we rate SVS Prime Tower the better fit for a very large room, and ELAC Debut Ref DFR52 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.
