Platinum 100 3G features a 1" MPD III Tweeter and 1 x 6" RDT III Woofer with a Crossover frequency at 2850 Hz. On the other hand, the RP-600M features a 1" Tractrix Horn Tweeter and 1 x 6.5" Cerametallic Woofer with a Crossover frequency at 1500Hz.
Frequency Response
Platinum 100 3G has a frequency range of 28-60k Hz whereas RP-600M has a frequency range of 45-25k Hz. With a minimum frequency of 28Hz, the Platinum 100 3G can go significantly deeper on the low side and provide stronger bass compared to the RP-600M's min frequency of 45Hz.
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 Bookshelf class in our database.

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 RP-600M 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 RP-600M's is rated at 96 dB. This 11 dB difference makes the Klipsch RP-600M 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 RP-600M has a max power handling value of 100 watts RMS, 50 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 RP-600M features dual binding post speaker terminals for bi-amping or bi-wiring.

Klipsch RP-600M's Dual binding posts/bi-wire/bi-amp terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Platinum 100 3G and RP-600M 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 100 3G's and Klipsch RP-600M'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 Klipsch RP-600M has external dimensions of 399.0 x 202.0 x 301.0mm ( 15.7 x 7.9 x 11.8inch) .
Klipsch RP-600M is 23mm narrower and 24mm less deeper than Monitor Audio Platinum 100 3G but it is also 1mm taller.
Below you can see the front view size comparison of Monitor Audio Platinum 100 3G and Klipsch RP-600M in scale.

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 Klipsch RP-600M is approximately 608.0cm2 / 94.2inch2. The Platinum 100 3G requires 20% more surface area than the RP-600M which gives it a small disadvantage on placement in tight spaces.
