SX6 features a 1" Silk Soft-Dome Tweeter and 1 x 5" Polymer treated Woofer with a Crossover frequency at 3500Hz. On the other hand, the Debut 2.0 B5.2 features a 1" Cloth Soft-dome Tweeter and 1 x 5.25" Woven Aramid-Fiber Woofer with a Crossover frequency at 2200Hz.
Frequency Response
SX6 has a frequency range of 60-20k Hz whereas Debut 2.0 B5.2 has a frequency range of 46-35k Hz. With a minimum frequency of 46Hz, the Debut 2.0 B5.2 can go significantly deeper on the low side and provide stronger bass compared to the SX6's min frequency of 60Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf 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
SX6 is a 8 ohms speaker compared to the Debut 2.0 B5.2 which has a nominal impedance of 6 ohms.
These two speakers also have different sensitivity levels. SX6 sensitivity is rated at 89 dB and the Debut 2.0 B5.2's is rated at 86 dB. This 3 dB difference makes the Fluance SX6 a more sensitive speaker compared to ELAC Debut 2.0 B5.2, hence will play louder with the same amount of watts.
Sensitivity
Bookshelf 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.
Debut 2.0 B5.2 can handle a max power of 120 watts RMS, whereas SX6 has a max power handling value of 100 watts RMS, 20 watts less than the Debut 2.0 B5.2.
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
SX6 features 5-Way Metal post type posts and Debut 2.0 B5.2 has a 5-Way Metal post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
SX6 has a rear firing port whereas Debut 2.0 B5.2 has a front firing ports. ELAC Debut 2.0 B5.2's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Fluance SX6 with its rear-firing port.
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 Fluance SX6's and ELAC Debut 2.0 B5.2's external dimensions. Fluance SX6 has external dimensions of 322.0 x 213.0 x 248.0mm (12-11/16 x 8-3/8 x 9-3/4inch) whereas ELAC Debut 2.0 B5.2 has external dimensions of 341.0 x 180.0 x 234.0mm (13.4 x 7.0 x 9.2inch).
ELAC Debut 2.0 B5.2 is 33mm narrower and 14mm less deeper than Fluance SX6 but it is also 19mm taller.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Fluance SX6 needs about 25% more floor or shelf area. ELAC Debut 2.0 B5.2 is 19mm taller.
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 Fluance SX6 is approximately 528.2cm2 / 81.9inch2 and base area of the ELAC Debut 2.0 B5.2 is approximately 421.2cm2 / 65.3inch2. The SX6 requires 25% more surface area than the Debut 2.0 B5.2 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 Fluance SX6 weighs 5.10kg / 11.2lbs and the ELAC Debut 2.0 B5.2 weighs 5.90kg / 13lbs. This makes the Debut 2.0 B5.2 16% heavier than the SX6.
Here is a comparison of how SX6 and Debut 2.0 B5.2's weights compare with the average, max and min weights in Passive Bookshelf class.

These sit in different price classes - ELAC Debut 2.0 B5.2 costs roughly 2.2x what Fluance SX6 does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | B | ELAC Debut 2.0 B5.2 digs deeper - 46Hz against 60Hz. |
| Amplifier needs | A | Fluance SX6 is more sensitive (89dB vs 86dB), so it goes louder on the same amplifier. |
| Amplifier match | A | Fluance SX6 is the easier load at 8 ohms. |
| Headroom | evenly matched | Similar power handling (100W vs 120W). |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | Neither adds bi-amping, a sub output or height drivers. ELAC Debut 2.0 B5.2 sits in a wider range (11 models), so a matched surround system is easier later. |
| Price | A | Fluance SX6 is cheaper - $150 against $330, about 55% less; arguably a different class. |
A Fluance SX6 B ELAC Debut 2.0 B5.2
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?
Fluance SX6 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 60Hz anyway, which makes the cheaper Fluance SX6 much easier to justify. Match it to your room: we rate Fluance SX6 the better fit for near-field listening and a small room, and ELAC Debut 2.0 B5.2 for a mid-size room and a large 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.
