Bronze 2 features a 1" Dome Tweeter and 1 x 6.5" C-CAM Woofer with a Crossover frequency at 3100Hz. 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
Bronze 2 has a frequency range of 42-30k Hz whereas M106 has a frequency range of 59Hz- 20kHz. With a minimum frequency of 42Hz, the Bronze 2 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
Bronze 2 and M106 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Bronze 2 sensitivity is rated at 90 dB and the M106's is at 87 dB. This 3 dB difference makes the Monitor Audio Bronze 2 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 Bronze 2 has a max power handling value of 100 watts RMS, 50 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.
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
Bronze 2 features 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
Bronze 2 has a front firing port whereas M106 has a rear firing ports. Monitor Audio Bronze 2's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Revel M106 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 Monitor Audio Bronze 2's and Revel M106's external dimensions. Monitor Audio Bronze 2 has external dimensions of 350.0 x 185.0 x 281.0mm (13.7 x 7.2 x 11.0inch) whereas Revel M106 has external dimensions of 383.0 x 210.0 x 280.0mm (15-1/16 x 8-1/4 x 11inch).
Monitor Audio Bronze 2 is 25mm narrower and 33mm shorter than Revel M106 but it is also 1mm deeper.
Below you can see the front view size comparison of Monitor Audio Bronze 2 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 Monitor Audio Bronze 2 is approximately 519.9cm2 / 80.6inch2 and base area of the Revel M106 is approximately 588.0cm2 / 91.1inch2. The Bronze 2 requires 12% less surface area than the M106 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 Monitor Audio Bronze 2 weighs 5.30kg / 11.7lbs and the Revel M106 weighs 8.41kg / 18.5lbs. This makes the M106 59% heavier than the Bronze 2.

These sit in different price classes - Revel M106 costs roughly 5.8x what Monitor Audio Bronze 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 | A | Monitor Audio Bronze 2 digs deeper - 42Hz against 59Hz. |
| Amplifier needs | A | Monitor Audio Bronze 2 is more sensitive (90dB vs 87dB), so it goes louder on the same amplifier. |
| Headroom | B | Revel M106 takes more power (150W vs 100W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | A | Monitor Audio Bronze 2: bi-amping. Monitor Audio Bronze 2 sits in a wider range (11 models), so a matched surround system is easier later. |
| Price | A | Monitor Audio Bronze 2 is cheaper - $379 against $2,200, about 83% less; arguably a different class. |
A Monitor Audio Bronze 2 B Revel M106
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?
Monitor Audio Bronze 2 is the easier recommendation: it leads on most of the measured areas and costs less. Take Revel M106 if its size, looks or fit in your room suit you better. 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. Match it to your room: we rate Monitor Audio Bronze 2 the better fit for near-field listening and a small room, and Revel M106 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.
