Platinum C250 3G features a 1" MPD III Tweeter, a 2.5" Midrange and 2 x 5" RDT III Woofer with a Crossover frequency at 850 Hz - 3500 Hz. On the other hand, the Platinum 200 3G features a 1" MPD III Tweeter, a 4" Midrange and 1 x 6" RDT III Woofer with a Crossover frequency at 825 Hz - 3000Hz.
Frequency Response
Platinum C250 3G has a frequency range of 30-60k Hz whereas Platinum 200 3G has a frequency range of 23-60k Hz. With a minimum frequency of 23Hz, the Platinum 200 3G can go significantly deeper on the low side and provide stronger bass compared to the Platinum C250 3G's min frequency of 30Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Platinum C250 3G and Platinum 200 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Platinum C250 3G and Platinum 200 3G have the same power range of up to 300 watts.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.

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 200 3G is approximately 1674.4cm2 / 259.5inch2. The Platinum C250 3G requires 23% more surface area than the Platinum 200 3G which gives it a small disadvantage on placement in tight spaces.
