Platinum 300 3G features a 1" MPD III Tweeter , a 4" Midrange and 2 x 8" RDT III Woofer with a Crossover frequency at 650 Hz - 3000 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 300 3G has a frequency range of 17-60k Hz whereas Platinum 200 3G has a frequency range of 23-60k Hz. With a minimum frequency of 17Hz, the Platinum 300 3G can go significantly deeper on the low side and provide stronger bass compared to the Platinum 200 3G's min frequency of 23Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Floor-standing class in our database.

Impedance and Sensitivity
Platinum 300 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 300 3G and the Platinum 300 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 300 3G can handle a max power of 400 watts RMS from the amp the whereas Platinum 200 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 300 3G and Platinum 200 3G features dual binding post speaker terminals for bi-amping or bi-wiring.
Monitor Audio Platinum 300 3G's Binding post terminals allows Bi-amping or bi-wiring
Monitor Audio Platinum 200 3G's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Platinum 300 3G and Platinum 200 3G have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.

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 300 3G's and Monitor Audio Platinum 200 3G's external dimensions. 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) whereas Monitor Audio Platinum 200 3G has external dimensions of 1041.6 x 368.7 x 454.9 mm ( 41 x 14.5 x 17.8-inch) .
Monitor Audio Platinum 300 3G is clearly the larger of the two speakers. Its body is 62mm wider, 90mm taller and 70mm deeper than Monitor Audio Platinum 200 3G.
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 300 3G is approximately 2257.5cm2 / 349.9inch2 and base area of the Monitor Audio Platinum 200 3G is approximately 1674.4cm2 / 259.5inch2. The Platinum 300 3G requires 35% more surface area than the Platinum 200 3G which gives it a small disadvantage 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 300 3G weighs 53.60kg / 117.9lbs and the Monitor Audio Platinum 200 3G weighs 35.80kg / 78.8lbs. This makes the Platinum 300 3G 50% heavier than the Platinum 200 3G.
Here is a comparison of how Platinum 300 3G and Platinum 200 3G's weights compare with the average, max and min weights in Passive Floor-standing class.
