Impedance and Sensitivity
Platinum C250 3G and Platinum 300 3G have the same Impedance of 4 ohms and their sensitivity is also same at 88 dB.
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 400 watts RMS from the amp the whereas Platinum C250 3G has a max power handling value of 300 watts RMS , 100 watts less than the Platinum 300 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 300 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 300 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 300 3G has external dimensions of 1131.1 x 429.8 x 525 mm ( 44.5 x 16.9 x 20.6-inch) .
Monitor Audio Platinum C250 3G is 906mm shorter and 199mm less deeper than Monitor Audio Platinum 300 3G but it is also 200mm wider.
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 300 3G is approximately 2257.5cm2 / 349.9inch2. The Platinum C250 3G requires 9% less surface area than the Platinum 300 3G which gives it a small advantage on placement in tight spaces.
