Alpha P5 features a 0.75" anodized aluminum Hard-Dome Tweeter and 1 x 5.25" Polypropylene Woofer with a Crossover frequency at 2500Hz. On the other hand, the Bronze 2 features a 1" Dome Tweeter and 1 x 6.5" C-CAM Woofer with a Crossover frequency at 3100Hz.
Frequency Response
Alpha P5 has a frequency range of 55-21k Hz whereas Bronze 2 has a frequency range of 42-30k Hz. With a minimum frequency of 42Hz, the Bronze 2 can go significantly deeper on the low side and provide stronger bass compared to the Alpha P5'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
Alpha P5 and Bronze 2 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Alpha P5 sensitivity is rated at 89 dB and the Bronze 2's is at 90 dB. This 1 dB difference makes the Monitor Audio Bronze 2 a more sensitive speaker compared to PSB P5, 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.
Alpha P5 can handle a max power of 100 watts RMS from the amp the whereas Alpha P5 has a max power handling value of 90 watts RMS , 10 watts less than the Bronze 2.
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 2 features Post posts which make bi-amping or bi-wiring possible. Alpha P5 has a 5-way post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Alpha P5 has a rear firing port whereas Bronze 2 has a front firing ports. Monitor Audio Bronze 2's front-firing port gives more flexibility in placement in regards to proximity to walls compared to PSB P5 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 PSB P5's and Monitor Audio Bronze 2's external dimensions. PSB P5 has external dimensions of 289.0 x 172.0 x 254.0mm ( 11-3/8 x 6-3/4 x 10inch) whereas Monitor Audio Bronze 2 has external dimensions of 350.0 x 185.0 x 281.0mm ( 13.7 x 7.2 x 11.0inch) .
Monitor Audio Bronze 2 is clearly the larger of the two speakers. Its body is 13mm wider, 61mm taller and 27mm deeper than PSB P5.
Below you can see the front view size comparison of PSB P5 and Monitor Audio Bronze 2 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 PSB P5 is approximately 436.9cm2 / 67.7inch2 and base area of the Monitor Audio Bronze 2 is approximately 519.9cm2 / 80.6inch2. The Alpha P5 requires 16% less surface area than the Bronze 2 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 PSB P5 weighs 4.61kg / 10.1lbs and the Monitor Audio Bronze 2 weighs 5.30kg / 11.7lbs. This makes the Bronze 2 15% heavier than the Alpha P5.
