What size room are the B&W 606 S2 and Revel M106 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

606 S2 AE features a 1" Aluminum Decoupled Double Dome Tweeter and 1 x 6.5" Continuum Woofer. On the other hand, the M106 features a 1" aluminum Hard-Dome with Acoustic Lens Waveguide Tweeter and 1 x 6.5" Aluminum Woofer with a Crossover frequency at 2300Hz.
Frequency Response
606 S2 AE has a frequency range of 52-28k Hz whereas M106 has a frequency range of 59Hz- 20kHz. With a minimum frequency of 52Hz, the 606 S2 AE can go significantly deeper on the low side and provide stronger bass compared to the M106's min frequency of 59Hz.
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
606 S2 AE and M106 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. 606 S2 AE sensitivity is rated at 88 dB and the M106's is at 87 dB. This 1 dB difference makes the B&W 606 S2 a more sensitive speaker compared to Revel M106, 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.
M106 can handle a max power of 150 watts RMS, whereas 606 S2 AE has a max power handling value of 120 watts RMS, 30 watts less than the M106.
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.

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
606 S2 AE features Binding post posts which make bi-amping or bi-wiring possible. M106 has a Binding post which doesn't feature bi-amping/bi-wiring.

Revel M106's Binding post terminals
Cabinet Type and Port Position
Both 606 S2 AE and M106 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 B&W 606 S2's and Revel M106's external dimensions. B&W 606 S2 has external dimensions of 347.0 x 191.0 x 326.0mm (13-5/8 x 7-1/2 x 12-13/16inch) whereas Revel M106 has external dimensions of 383.0 x 210.0 x 280.0mm (15-1/16 x 8-1/4 x 11inch).
B&W 606 S2 is 19mm narrower and 36mm shorter than Revel M106 but it is also 46mm deeper.
Below you can see the front view size comparison of B&W 606 S2 and Revel M106 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 S2 is approximately 622.7cm2 / 96.5inch2 and base area of the Revel M106 is approximately 588.0cm2 / 91.1inch2. The 606 S2 AE requires 6% more surface area than the M106 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 S2 weighs 6.90kg / 15.2lbs and the Revel M106 weighs 8.41kg / 18.5lbs. This makes the M106 22% heavier than the 606 S2 AE.
Here is a comparison of how 606 S2 AE and M106's weights compare with the average, max and min weights in Passive Bookshelf class.

These sit in different price classes - Revel M106 costs roughly 2.2x what B&W 606 S2 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 |
A |
B&W 606 S2 digs deeper - 52Hz against 59Hz. A subwoofer would even that out. |
| Amplifier needs |
evenly matched |
Similar sensitivity (88dB vs 87dB) - both want much the same power. |
| Headroom |
B |
Revel M106 takes more power (150W vs 120W) - more in hand in a big room. |
| Size |
depends |
Similar cabinet size - neither is easier to fit. |
| Expandability |
depends |
B&W 606 S2: bi-amping. Revel M106 sits in a wider range (8 models), so a matched surround system is easier later. |
| Price |
A |
B&W 606 S2 is cheaper - $999 against $2,200, about 55% less; arguably a different class. |

depends neither is better in the abstract - it turns on your room, placement 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?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 59Hz anyway, so judge these on the other rows instead. Think about the whole system, not just the speakers: the roughly $1,201 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
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.
