Debut 3.0 DF63 features a 1" Hard-Dome Tweeter, a 6.5" Midrange and 2 x 6.5" Aramid fiber Woofer with a Crossover frequency at 550Hz and 2000Hz. On the other hand, the 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.
Frequency Response
Debut 3.0 DF63 has a frequency range of 31 to 38K Hz whereas Prime Tower has a frequency range of 30-25k Hz. With a minimum frequency of 30Hz, the Prime Tower can go slightly deeper then the Debut 3.0 DF63's min frequency of 31Hz.
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
Debut 3.0 DF63 is a 4 ohms speaker compared to the Prime Tower which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Debut 3.0 DF63 can provide this impedance level.
These two speakers also have different sensitivity levels. Debut 3.0 DF63 sensitivity is rated at 87.5 dB and the Prime Tower's is rated at 87 dB. This 1 dB difference makes the ELAC Debut 3.0 DF63 a more sensitive speaker compared to SVS Prime Tower, 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.
Prime Tower can handle a max power of 250 watts RMS, whereas Debut 3.0 DF63 has a max power handling value of 180 watts RMS, 70 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.
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
Debut 3.0 DF63 features 5-Way post type posts and Prime Tower has a 5-Way post type posts. None of these speakers feature bi-amping/bi-wiring.

SVS Prime Tower's 5-Way post terminals
Cabinet Type and Port Position
Both Debut 3.0 DF63 and Prime Tower 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 ELAC Debut 3.0 DF63's and SVS Prime Tower's external dimensions. ELAC Debut 3.0 DF63 has external dimensions of 1094.0 x 245.0 x 320.0mm (43-1/16-inch x 9-5/8-inch x 12-9/16-inch) whereas SVS Prime Tower has external dimensions of 931.0 x 204.0 x 297.0mm (36-5/8 x 8 x 11-11/16inch).
ELAC Debut 3.0 DF63 is clearly the larger of the two speakers. Its body is 41mm wider, 163mm taller and 23mm deeper than SVS Prime Tower.
Below you can see the front view size comparison of ELAC Debut 3.0 DF63 and SVS Prime Tower 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 Debut 3.0 DF63 is approximately 784.0cm2 / 121.5inch2 and base area of the SVS Prime Tower is approximately 605.9cm2 / 93.9inch2. The Debut 3.0 DF63 requires 29% more surface area than the Prime Tower 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 ELAC Debut 3.0 DF63 weighs 17.64kg / 38.8lbs and the SVS Prime Tower weighs 18.23kg / 40.1lbs. This makes the Prime Tower 3% heavier than the Debut 3.0 DF63.
Here is a comparison of how Debut 3.0 DF63 and Prime Tower's weights compare with the average, max and min weights in Passive Floor-standing class.

A generation apart: ELAC Debut 3.0 DF63 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 | evenly matched | Much the same reach (31Hz vs 30Hz). |
| Amplifier needs | evenly matched | Similar sensitivity (88dB vs 87dB) - both want much the same power. |
| Amplifier match | B | SVS Prime Tower is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | B | SVS Prime Tower takes more power (250W vs 180W) - more in hand in a big room. |
| Size | depends | SVS Prime Tower is easier to place; ELAC Debut 3.0 DF63 is bigger, which usually goes with fuller bass. Your room decides. |
| Price | A | ELAC Debut 3.0 DF63 is cheaper - $1,099 against $1,400, about 22% less. |
A ELAC Debut 3.0 DF63 B SVS Prime Tower
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?
The usual trade-off: SVS Prime Tower measures better, ELAC Debut 3.0 DF63 costs about about 27% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. In a large or open-plan room, ELAC Debut 3.0 DF63 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, SVS Prime Tower is the easier speaker to get right. If your amplifier is modest, vintage or valve-based, SVS Prime Tower is the safer partner - the other will want more current or more watts to sound its best.
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.
