Borea BR03 features a 1" silk Tweeter and 1 x 6" fiberglass Woofer with a Crossover frequency at 3600Hz. 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
Borea BR03 has a frequency range of 46 - 22k 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 Borea BR03's min frequency of 46Hz.
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
Borea BR03 and Bronze 100 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Borea BR03 sensitivity is rated at 90 dB and the Bronze 100's is at 87 dB. This 3 dB difference makes the Triangle Borea BR03 a more sensitive speaker compared to Monitor Audio Bronze 100, hence will play louder with the same amount of watts.

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.
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. Borea BR03 has a Binding post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Borea BR03 has a front firing port whereas Bronze 100 has a rear firing ports. Triangle Borea BR03's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Monitor Audio Bronze 100 with its rear-firing port.
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 Triangle Borea BR03's and Monitor Audio Bronze 100's external dimensions. Triangle Borea BR03 has external dimensions of 380.0 x 206.0 x 314.0mm ( 14.9 x 8.1 x 12.3inch) 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) .
Triangle Borea BR03 is 25mm narrower and 11mm less deeper than Monitor Audio Bronze 100 but it is also 4mm taller.
Below you can see the front view size comparison of Triangle Borea BR03 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 Triangle Borea BR03 is approximately 646.8cm2 / 100.3inch2 and base area of the Monitor Audio Bronze 100 is approximately 750.8cm2 / 116.4inch2. The Borea BR03 requires 14% 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 Triangle Borea BR03 weighs 6.26kg / 13.8lbs and the Monitor Audio Bronze 100 weighs 7.80kg / 17.2lbs. This makes the Bronze 100 25% heavier than the Borea BR03.
