In this review, we will be comparing Oberon 3 and Bronze 100, two Passive Bookshelf speakers from DALI and Monitor Audio. Let's have a brief look at the main features
of DALI Oberon 3 and Monitor Audio Bronze 100 first before getting into our more
detailed comparison.
What size room are the DALI Oberon 3 and Monitor Audio Bronze 100 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:

Oberon 3 features a 1.125" Soft-Dome Tweeter and 1 x 7" Wood Fiber Woofer with a Crossover frequency at 2400Hz. On the other hand, the Bronze 100 features a 1" Hard-Dome Tweeter and 1 x 8" C-CAM Woofer with a Crossover frequency at 2200Hz.
Frequency Response
Oberon 3 has a frequency range of 47-26k Hz whereas Bronze 100 has a frequency range of 37-30k Hz. With a minimum frequency of 37Hz, the Bronze 100 can go significantly deeper on the low side and provide stronger bass compared to the Oberon 3's min frequency of 47Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Bookshelf class in our database.

None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Oberon 3 is a 6 ohms speaker compared to the Bronze 100 which has a nominal impedance of 8 ohms.
On the other hand, they have the same sensitivity of 87 dBdB.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
Oberon 3 can handle a max power of 150 watts RMS from the amp the whereas Bronze 100 has a max power handling value of 100 watts RMS, 50 watts less than the Oberon 3.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Bronze 100 features Post posts which make bi-amping or bi-wiring possible. Oberon 3 has a Post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Oberon 3 and Bronze 100 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
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare DALI Oberon 3's and Monitor Audio Bronze 100's external dimensions. DALI Oberon 3 has external dimensions of 350.0 x 201.0 x 310.0mm ( 13-3/4 x 7-7/8 x 12-3/16inch) whereas Monitor Audio Bronze 100 has external dimensions of 376.0 x 231.0 x 325.0mm ( 14.8 x 9.0 x 12.7inch) .
Monitor Audio Bronze 100 is clearly the larger of the two speakers. Its body is 30mm wider, 26mm taller and 15mm deeper than DALI Oberon 3.
Below you can see the front view size comparison of DALI Oberon 3 and Monitor Audio Bronze 100 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 DALI Oberon 3 is approximately 623.1cm2 / 96.6inch2 and base area of the Monitor Audio Bronze 100 is approximately 750.8cm2 / 116.4inch2. The Oberon 3 requires 17% less surface area than the Bronze 100 which gives it a small advantage on placement in tight spaces.
Here is an 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 DALI Oberon 3 weighs 6.32kg / 13.9lbs and the Monitor Audio Bronze 100 weighs 7.80kg / 17.2lbs. This makes the Bronze 100 23% heavier than the Oberon 3.
