Airmotiv XB1 features a 1" Airmotiv folded ribbon Folded Motion Tweeter and 1 x 4" Woven fibre Woofer with a Crossover frequency at 2600Hz. 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
Airmotiv XB1 has a frequency range of 65-27k 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 Airmotiv XB1's min frequency of 65Hz.
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
Airmotiv XB1 is a 4 ohms speaker compared to the Debut 2.0 B5.2 which has a nominal impedance of 6 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 Airmotiv XB1 can provide this impedance level.
These two speakers also have different sensitivity levels. Airmotiv XB1 sensitivity is rated at 82 dB and the Debut 2.0 B5.2's is rated at 86 dB. This 4 dB difference makes the ELAC Debut 2.0 B5.2 a more sensitive speaker compared to Emotiva Airmotiv XB1, 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.
Both handle the same maximum of 120 watts RMS, though Airmotiv XB1 is rated 50-120 watts and Debut 2.0 B5.2 120 watts.
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
Airmotiv XB1 features Binding post posts which make bi-amping or bi-wiring possible. Debut 2.0 B5.2 has a 5-Way Metal post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Airmotiv XB1 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 Emotiva Airmotiv XB1 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 Emotiva Airmotiv XB1's and ELAC Debut 2.0 B5.2's external dimensions. Emotiva Airmotiv XB1 has external dimensions of 260.0 x 165.0 x 201.0mm (10-1/4 x 6-1/2 x 7-15/16inch) 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 clearly the larger of the two speakers. Its body is 15mm wider, 81mm taller and 33mm deeper than Emotiva Airmotiv XB1.
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.
ELAC Debut 2.0 B5.2 needs about 27% more floor or shelf area. ELAC Debut 2.0 B5.2 is 33mm deeper, so it stands that much further out from the wall. ELAC Debut 2.0 B5.2 is 81mm 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 Emotiva Airmotiv XB1 is approximately 331.7cm2 / 51.4inch2 and base area of the ELAC Debut 2.0 B5.2 is approximately 421.2cm2 / 65.3inch2. The Airmotiv XB1 requires 21% less surface area than the Debut 2.0 B5.2 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 Emotiva Airmotiv XB1 weighs 3.74kg / 8.2lbs and the ELAC Debut 2.0 B5.2 weighs 5.90kg / 13lbs. This makes the Debut 2.0 B5.2 58% heavier than the Airmotiv XB1.
Here is a comparison of how Airmotiv XB1 and Debut 2.0 B5.2's weights compare with the average, max and min weights in Passive Bookshelf class.

A generation apart: Emotiva Airmotiv XB1 is the newer design, against a 2018 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | B | ELAC Debut 2.0 B5.2 digs deeper - 46Hz against 65Hz. |
| Amplifier needs | B | ELAC Debut 2.0 B5.2 is more sensitive (86dB vs 82dB), so it goes louder on the same amplifier. |
| Amplifier match | B | ELAC Debut 2.0 B5.2 is the easier load at 6 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | evenly matched | Similar power handling (120W vs 120W). |
| Size | depends | Emotiva Airmotiv XB1 is easier to place; ELAC Debut 2.0 B5.2 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | A | Emotiva Airmotiv XB1: bi-amping. |
| Price | A | Emotiva Airmotiv XB1 is cheaper - $219 against $330, about 34% less. |
A Emotiva Airmotiv XB1 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?
The usual trade-off: ELAC Debut 2.0 B5.2 measures better, Emotiva Airmotiv XB1 costs about about 51% 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. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 65Hz anyway, which makes the cheaper Emotiva Airmotiv XB1 much easier to justify. Match it to your room: we rate Emotiva Airmotiv XB1 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.
