Bronze 1 features a 1" Dome Tweeter and 1 x 5.5" C-CAM Woofer with a Crossover frequency at 2700Hz. On the other hand, the L100 features a 1" Ring Radiator Tweeter and 1 x 5.25" Polypropylene Woofer with a Crossover frequency at 2900Hz.
Frequency Response
Bronze 1 has a frequency range of 55-30k Hz whereas L100 has a frequency range of 57-38k Hz. With a minimum frequency of 55Hz, the Bronze 1 can go slightly deeper then the L100's min frequency of 57Hz.
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.
Low Frequency
Bookshelf Speakers
High Frequency
Bookshelf Speakers
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
Bronze 1 is a 8 ohms speaker compared to the L100 which has a nominal impedance of 4 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the L100 can provide this impedance level.
These two speakers also have different sensitivity levels. Bronze 1 sensitivity is rated at 88 dB and the L100's is rated at 85.5 dB. This 2 dB difference makes the Monitor Audio Bronze 1 a more sensitive speaker compared to Polk L100, 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.
Bronze 1 can handle a max power of 160 watts RMS from the amp the whereas Bronze 1 has a max power handling value of 70 watts RMS , 90 watts less than the L100.
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 1 features Post type posts and L100 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Bronze 1 and L100 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 Monitor Audio Bronze 1's and Polk L100's external dimensions. Monitor Audio Bronze 1 has external dimensions of 260.0 x 165.0 x 205.0mm ( 10.2 x 6.4 x 8.0inch) whereas Polk L100 has external dimensions of 348.0 x 201.0 x 288.0mm ( 13-11/16 x 7-7/8 x 11-5/16inch) .
Polk L100 is clearly the larger of the two speakers. Its body is 36mm wider, 88mm taller and 83mm deeper than Monitor Audio Bronze 1.
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 1 is approximately 338.3cm2 / 52.4inch2 and base area of the Polk L100 is approximately 578.9cm2 / 89.7inch2. The Bronze 1 requires 42% less surface area than the L100 which gives it a small advantage on placement in tight spaces.
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 1 weighs 3.50kg / 7.7lbs and the Polk L100 weighs 7.68kg / 16.9lbs. This makes the L100 119% heavier than the Bronze 1.
Here is a comparison of how Bronze 1 and L100's weights compare with the average, max and min weights in Passive Bookshelf class.
