Diamond 225 features a 1" Dome Tweeter and 1 x 6.5" Woven Kevlar Woofer with a Crossover frequency at 2300Hz. On the other hand, the Bronze 1 features a 1" Dome Tweeter and 1 x 5.5" C-CAM Woofer with a Crossover frequency at 2700Hz.
Frequency Response
Diamond 225 has a frequency range of 45-20k Hz whereas Bronze 1 has a frequency range of 55-30k Hz. With a minimum frequency of 45Hz, the Diamond 225 can go significantly deeper on the low side and provide stronger bass compared to the Bronze 1's min frequency of 55Hz.
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
Diamond 225 and Bronze 1 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Diamond 225 sensitivity is rated at 87 dB and the Bronze 1's is at 88 dB. This 1 dB difference makes the Monitor Audio Bronze 1 a more sensitive speaker compared to Wharfedale 225, 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.
Diamond 225 can handle a max power of 120 watts RMS from the amp the whereas Bronze 1 has a max power handling value of 70 watts RMS, 50 watts less than the Diamond 225.
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
Diamond 225 features Post posts which make bi-amping or bi-wiring possible. Bronze 1 has a Post which doesn't feature bi-amping/bi-wiring.
Wharfedale 225's Post terminals allows Bi-amping or bi-wiring

Cabinet Type and Port Position
Diamond 225 has a bottom firing port whereas Bronze 1 has a rear firing ports. Wharfedale 225's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Monitor Audio Bronze 1 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 Wharfedale 225's and Monitor Audio Bronze 1's external dimensions. Wharfedale 225 has external dimensions of 355.0 x 196.0 x 290.0mm ( 13.9 x 7.7 x 11.4inch) whereas Monitor Audio Bronze 1 has external dimensions of 260.0 x 165.0 x 205.0mm ( 10.2 x 6.4 x 8.0inch) .
Wharfedale 225 is clearly the larger of the two speakers. Its body is 31mm wider, 95mm taller and 85mm 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 Wharfedale 225 is approximately 568.4cm2 / 88.1inch2 and base area of the Monitor Audio Bronze 1 is approximately 338.3cm2 / 52.4inch2. The Diamond 225 requires 68% more surface area than the Bronze 1 which gives it a small disadvantage 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 Wharfedale 225 weighs 6.55kg / 14.4lbs and the Monitor Audio Bronze 1 weighs 3.50kg / 7.7lbs. This makes the Diamond 225 87% heavier than the Bronze 1.
Here is a comparison of how Diamond 225 and Bronze 1's weights compare with the average, max and min weights in Passive Bookshelf class.
