BW 606 features a 1" Decoupled Carbon Hard-Dome Tweeter and 1 x 6.5" Continuum Woofer. 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
BW 606 has a frequency range of 52-28k 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 BW 606's min frequency of 52Hz.
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
BW 606 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. BW 606 sensitivity is rated at 88 dB and the Debut 2.0 B5.2's is rated at 86 dB. This 2 dB difference makes the B&W 606 a more sensitive speaker compared to ELAC Debut 2.0 B5.2, hence will play louder with the same amount of watts.
Sensitivity

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 BW 606 is rated 30-120 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
BW 606 features 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
BW 606 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 B&W 606 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 B&W 606's and ELAC Debut 2.0 B5.2's external dimensions. B&W 606 has external dimensions of 345.0 x 190.0 x 324.0mm (13.5 x 7.4 x 12.7inch) 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).
B&W 606 is clearly the larger of the two speakers. Its body is 10mm wider, 4mm taller and 90mm deeper than ELAC Debut 2.0 B5.2.
Below you can see the front view size comparison of B&W 606 and ELAC Debut 2.0 B5.2 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 B&W 606 is approximately 615.6cm2 / 95.4inch2 and base area of the ELAC Debut 2.0 B5.2 is approximately 421.2cm2 / 65.3inch2. The BW 606 requires 46% more surface area than the Debut 2.0 B5.2 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 B&W 606 weighs 6.90kg / 15.2lbs and the ELAC Debut 2.0 B5.2 weighs 5.90kg / 13lbs. This makes the BW 606 17% heavier than the Debut 2.0 B5.2.

These sit in different price classes - B&W 606 costs roughly 2.7x what ELAC Debut 2.0 B5.2 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 52Hz. A subwoofer would even that out. |
| Amplifier needs | A | B&W 606 is more sensitive (88dB vs 86dB), so it goes louder on the same amplifier. |
| Amplifier match | A | B&W 606 is the easier load at 8 ohms. |
| Headroom | evenly matched | Similar power handling (120W vs 120W). |
| Size | depends | ELAC Debut 2.0 B5.2 is easier to place; B&W 606 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | B&W 606: bi-amping. ELAC Debut 2.0 B5.2 sits in a wider range (11 models), so a matched surround system is easier later. |
| Price | B | ELAC Debut 2.0 B5.2 is cheaper - $330 against $899, about 63% less; arguably a different class. |
A B&W 606 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?
B&W 606 is ahead, but only on 1 of the measured areas, and it costs about 2.7x the price. That is a lot of money for a narrow margin on paper - ELAC Debut 2.0 B5.2 looks like the sensible buy unless something else about the B&W 606 appeals to you. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 52Hz anyway, so judge these on the other rows instead. In a large or open-plan room, B&W 606 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, ELAC Debut 2.0 B5.2 is the easier speaker to get right.
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.
