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
Platinum 100 3G is a 4 ohms speaker compared to the Silver 100 7G which has a nominal impedance of 8 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 Platinum 100 3G can provide this impedance level.
These two speakers also have different sensitivity levels. Platinum 100 3G sensitivity is rated at 85dB and the Silver 100 7G's is rated at 87.5 dB. This 3 dB difference makes the Monitor Audio Silver 100 7G a more sensitive speaker compared to Monitor Audio Platinum 100 3G, 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.
Platinum 100 3G can handle a max power of 150 watts RMS from the amp the whereas Silver 100 7G has a max power handling value of 120 watts RMS, 30 watts less than the Platinum 100 3G.
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
Both Platinum 100 3G and Silver 100 7G features dual binding post speaker terminals for bi-amping or bi-wiring.

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 Platinum 100 3G's and Monitor Audio Silver 100 7G's external dimensions. Monitor Audio Platinum 100 3G has external dimensions of 398 x 225 x 325.6 mm ( 15.6 x 8.8 x 12.8-inch) whereas Monitor Audio Silver 100 7G has external dimensions of 377.0 x 232.0 x 332.0mm ( 14-13/16 x 9-1/8 x 13-1/16inch) .
Monitor Audio Platinum 100 3G is 7mm narrower and 7mm less deeper than Monitor Audio Silver 100 7G but it is also 21mm taller.
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 Platinum 100 3G is approximately 731.3cm2 / 113.4inch2 and base area of the Monitor Audio Silver 100 7G is approximately 770.2cm2 / 119.4inch2. The Platinum 100 3G requires 5% less surface area than the Silver 100 7G 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 Platinum 100 3G weighs 15.20kg / 33.4lbs and the Monitor Audio Silver 100 7G weighs 9.43kg / 20.7lbs. This makes the Platinum 100 3G 61% heavier than the Silver 100 7G.
Here is a comparison of how Platinum 100 3G and Silver 100 7G's weights compare with the average, max and min weights in Passive Bookshelf class.
