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 2 and SX-50 have the same Impedance of 8 ohms and their sensitivity is also same at 90 dB.

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 2 features Post posts which make bi-amping or bi-wiring possible. SX-50 has a 5-way post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Bronze 2 has a front firing port whereas SX-50 has a rear firing ports. Monitor Audio Bronze 2's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Cambridge SX-50 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 Monitor Audio Bronze 2's and Cambridge SX-50's external dimensions. Monitor Audio Bronze 2 has external dimensions of 350.0 x 185.0 x 281.0mm ( 13.7 x 7.2 x 11.0inch) whereas Cambridge SX-50 has external dimensions of 225.0 x 161.0 x 240.0mm ( 8.8 x 6.3 x 9.4inch) .
Monitor Audio Bronze 2 is clearly the larger of the two speakers. Its body is 24mm wider, 125mm taller and 41mm deeper than Cambridge SX-50.
Below you can see the front view size comparison of Monitor Audio Bronze 2 and Cambridge SX-50 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 2 is approximately 519.9cm2 / 80.6inch2 and base area of the Cambridge SX-50 is approximately 386.4cm2 / 59.9inch2. The Bronze 2 requires 35% more surface area than the SX-50 which gives it a small disadvantage 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 Monitor Audio Bronze 2 weighs 5.30kg / 11.7lbs and the Cambridge SX-50 weighs 3.00kg / 6.6lbs. This makes the Bronze 2 77% heavier than the SX-50.
