Airmotiv B2+ features a 25×32 mm" folded ribbon Tweeter and 1 x 6.25" woven fiber cone Woofer with a Crossover frequency at 2000Hz. On the other hand, the Debut 2.0 B6.2 features a 1" Cloth Soft-Dome Tweeter and 1 x 6.5" Woven Aramid-Fiber Woofer with a Crossover frequency at 2200Hz.
Frequency Response
Airmotiv B2+ has a frequency range of 40-28k Hz whereas Debut 2.0 B6.2 has a frequency range of 44-35k Hz. With a minimum frequency of 40Hz, the Airmotiv B2+ can go slightly deeper then the Debut 2.0 B6.2's min frequency of 44Hz.
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 B2+ is a 4 ohms speaker compared to the Debut 2.0 B6.2 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 B2+ can provide this impedance level.
These two speakers also have different sensitivity levels. Airmotiv B2+ sensitivity is rated at 86 dB and the Debut 2.0 B6.2's is rated at 87 dB. This 1 dB difference makes the ELAC Debut 2.0 B6.2 a more sensitive speaker compared to Emotiva Airmotiv B2+, 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.
Airmotiv B2+ can handle a max power of 125 watts RMS, whereas Debut 2.0 B6.2 has a max power handling value of 120 watts RMS, 5 watts less than the Airmotiv B2+.
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 B2+ features Binding post posts which make bi-amping or bi-wiring possible. Debut 2.0 B6.2 has a 5-Way post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Airmotiv B2+ has a rear firing port whereas Debut 2.0 B6.2 has a front firing ports. ELAC Debut 2.0 B6.2's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Emotiva Airmotiv B2+ 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 B2+'s and ELAC Debut 2.0 B6.2's external dimensions. Emotiva Airmotiv B2+ has external dimensions of 324.0 x 216.0 x 293.0mm (12-3/4-inch x 8-1/2-inch x 11-1/2-inch) whereas ELAC Debut 2.0 B6.2 has external dimensions of 375.0 x 195.0 x 268.0mm (14.7 x 7.6 x 10.5inch).
ELAC Debut 2.0 B6.2 is 21mm narrower and 25mm less deeper than Emotiva Airmotiv B2+ but it is also 51mm taller.
Below you can see the front view size comparison of Emotiva Airmotiv B2+ and ELAC Debut 2.0 B6.2 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 Emotiva Airmotiv B2+ is approximately 632.9cm2 / 98.1inch2 and base area of the ELAC Debut 2.0 B6.2 is approximately 522.6cm2 / 81.0inch2. The Airmotiv B2+ requires 21% more surface area than the Debut 2.0 B6.2 which gives it a small disadvantage 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 Emotiva Airmotiv B2+ weighs 7.10kg / 15.6lbs and the ELAC Debut 2.0 B6.2 weighs 7.40kg / 16.3lbs. This makes the Debut 2.0 B6.2 4% heavier than the Airmotiv B2+.
Here is a comparison of how Airmotiv B2+ and Debut 2.0 B6.2's weights compare with the average, max and min weights in Passive Bookshelf class.

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 | Emotiva Airmotiv B2+ digs deeper - 40Hz against 44Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (86dB vs 87dB) - both want much the same power. |
| Amplifier match | B | ELAC Debut 2.0 B6.2 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 (125W vs 120W). |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | A | Emotiva Airmotiv B2+: bi-amping. |
| Price | B | ELAC Debut 2.0 B6.2 is cheaper - $400 against $499, about 20% less. |
A Emotiva Airmotiv B2+ B ELAC Debut 2.0 B6.2
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: Emotiva Airmotiv B2+ measures better, ELAC Debut 2.0 B6.2 costs about about 25% 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. Match it to your room: we rate Emotiva Airmotiv B2+ the better fit for near-field listening and a small room, and ELAC Debut 2.0 B6.2 for a mid-size room and a large room. If your amplifier is modest, vintage or valve-based, ELAC Debut 2.0 B6.2 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.
