Bronze 100 features a 1" Hard-Dome Tweeter and 1 x 8" C-CAM Woofer with a Crossover frequency at 2200Hz. On the other hand, the Q150 features a 1" vented aluminum Dome Tweeter and 1 x 5.25" Aluminum Woofer with a Crossover frequency at 2500Hz.
Frequency Response
Bronze 100 has a frequency range of 37-30k Hz whereas Q150 has a frequency range of 51-28k 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 Q150's min frequency of 51Hz.
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.

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 100 and Q150 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Bronze 100 sensitivity is rated at 87 dB and the Q150's is at 86 dB. This 1 dB difference makes the Monitor Audio Bronze 100 a more sensitive speaker compared to KEF Q150, 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. Q150 has a Post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Bronze 100 and Q150 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 100's and KEF Q150's external dimensions. Monitor Audio Bronze 100 has external dimensions of 376.0 x 231.0 x 325.0mm ( 14.8 x 9.0 x 12.7inch) whereas KEF Q150 has external dimensions of 303.0 x 180.0 x 278.0mm ( 11.9 x 7.0 x 10.9inch) .
Monitor Audio Bronze 100 is clearly the larger of the two speakers. Its body is 51mm wider, 73mm taller and 47mm deeper than KEF Q150.
Below you can see the front view size comparison of Monitor Audio Bronze 100 and KEF Q150 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 100 is approximately 750.8cm2 / 116.4inch2 and base area of the KEF Q150 is approximately 500.4cm2 / 77.6inch2. The Bronze 100 requires 50% more surface area than the Q150 which gives it a small disadvantage on placement in tight spaces.
