Drivers
One of the fundamental differences between these two speakers is that Platinum C250 3G is a 3-way design whereas the Platinum 100 3G is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

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 C250 3G and Platinum 100 3G have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Platinum C250 3G sensitivity is rated at 88dB and the Platinum 100 3G's is at 85dB. This 3 dB difference makes the Monitor Audio Platinum C250 3G a more sensitive speaker compared to Monitor Audio Platinum 100 3G, hence will play louder with the same amount of watts.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Platinum C250 3G and the Platinum C250 3G can provide this impedance level.

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 C250 3G can handle a max power of 300 watts RMS from the amp the whereas Platinum 100 3G has a max power handling value of 150 watts RMS, 150 watts less than the Platinum C250 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 C250 3G and Platinum 100 3G 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 C250 3G's and Monitor Audio Platinum 100 3G's external dimensions. Monitor Audio Platinum C250 3G has external dimensions of 225 x 630 x 325.7 mm ( 8.8 x 24.8 x 12.8-inch) whereas 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) .
Monitor Audio Platinum 100 3G is 405mm narrower and 1mm less deeper than Monitor Audio Platinum C250 3G but it is also 173mm 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 C250 3G is approximately 2053.8cm2 / 318.3inch2 and base area of the Monitor Audio Platinum 100 3G is approximately 731.3cm2 / 113.4inch2. The Platinum C250 3G requires 181% more surface area than the Platinum 100 3G which gives it a small disadvantage on placement in tight spaces.
