Debut 3.0 DB63 features a 1" Hard-Dome Tweeter and 1 x 6.5" Aramid fiber Woofer with a Crossover frequency at 2000Hz. On the other hand, the Airmotiv XB2 features a 25×32 mm" folded ribbon Tweeter and 1 x 6" woven fiber cone Woofer with a Crossover frequency at 2600Hz.
Frequency Response
Debut 3.0 DB63 has a frequency range of 42 to 38K Hz whereas Airmotiv XB2 has a frequency range of 55 Hz – 27 kHz. With a minimum frequency of 42Hz, the Debut 3.0 DB63 can go significantly deeper on the low side and provide stronger bass compared to the Airmotiv XB2's min frequency of 55Hz.
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
Debut 3.0 DB63 is a 6 ohms speaker compared to the Airmotiv XB2 which has a nominal impedance of 4 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 XB2 can provide this impedance level.
These two speakers also have different sensitivity levels. Debut 3.0 DB63 sensitivity is rated at 87 dB and the Airmotiv XB2's is rated at 86 dB. This 1 dB difference makes the ELAC Debut 3.0 DB63 a more sensitive speaker compared to Emotiva Airmotiv XB2, 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 3.0 DB63 can handle a max power of 140 watts RMS, whereas Airmotiv XB2 has a max power handling value of 125 watts RMS, 15 watts less than the Debut 3.0 DB63.
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 XB2 features Binding post posts which make bi-amping or bi-wiring possible. Debut 3.0 DB63 has a 5-Way post which doesn't feature bi-amping/bi-wiring.

Emotiva Airmotiv XB2's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Debut 3.0 DB63 and Airmotiv XB2 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 DB63's and Emotiva Airmotiv XB2's external dimensions. ELAC Debut 3.0 DB63 has external dimensions of 340.0 x 197.0 x 312.0mm (13-3/8-inch x 7-3/4-inch x 12-1/4-inch) whereas Emotiva Airmotiv XB2 has external dimensions of 325 x 216 x 292 mm (12.8” x 8.5” x 11.5”).
Emotiva Airmotiv XB2 is 15mm shorter and 20mm less deeper than ELAC Debut 3.0 DB63 but it is also 19mm wider.
Below you can see the front view size comparison of ELAC Debut 3.0 DB63 and Emotiva Airmotiv XB2 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 DB63 is approximately 614.6cm2 / 95.3inch2 and base area of the Emotiva Airmotiv XB2 is approximately 630.7cm2 / 97.8inch2. The Debut 3.0 DB63 requires 3% less surface area than the Airmotiv XB2 which gives it a small advantage on placement in tight spaces.
Here is another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 DB63 weighs 7.86kg / 17.3lbs and the Emotiva Airmotiv XB2 weighs 8.16kg / 18lbs. This makes the Airmotiv XB2 4% heavier than the Debut 3.0 DB63.

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.
| Area | Better | Why |
|---|
| Bass | A | ELAC Debut 3.0 DB63 digs deeper - 42Hz against 55Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (87dB vs 86dB) - both want much the same power. |
| Amplifier match | A | ELAC Debut 3.0 DB63 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 (140W vs 125W). |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | B | Emotiva Airmotiv XB2: bi-amping. Emotiva Airmotiv XB2 sits in a wider range (10 models), so a matched surround system is easier later. |
| Price | A | ELAC Debut 3.0 DB63 is cheaper - $449 against $549, about 18% less. |
A ELAC Debut 3.0 DB63 B Emotiva Airmotiv XB2
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?
ELAC Debut 3.0 DB63 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 55Hz anyway, so judge these on the other rows instead. If your amplifier is modest, vintage or valve-based, ELAC Debut 3.0 DB63 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.
