In this review, we will be comparing Platinum C250 3G and R-34C, two Passive Center Channel speakers from Monitor Audio and Klipsch. Let's have a brief look at the main features
of Monitor Audio Platinum C250 3G and Klipsch R-34C first before getting into our more
detailed comparison.
What size room are the Monitor Audio Platinum C250 3G and Klipsch R-34C speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the Monitor Audio Platinum C250 3G and Klipsch R-34C compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Platinum C250 3G is a 3-way design whereas the R-34C 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.

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 R-34C features a 1" aluminum Tractrix horn Tweeter and 4 x 3.5" copper spun IMG Woofer .
Frequency Response
Platinum C250 3G has a frequency range of 30-60k Hz whereas R-34C has a frequency range of 82-21k Hz. With a minimum frequency of 30Hz, the Platinum C250 3G can go significantly deeper on the low side and provide stronger bass compared to the R-34C's min frequency of 82Hz.
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 Center Channel 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 C250 3G is a 4 ohms speaker compared to the R-34C 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 C250 3G can provide this impedance level.
These two speakers also have different sensitivity levels. Platinum C250 3G sensitivity is rated at 88dB and the R-34C's is rated at 96 dB. This 8 dB difference makes the Klipsch R-34C a more sensitive speaker compared to Monitor Audio Platinum C250 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 C250 3G can handle a max power of 300 watts RMS from the amp the whereas R-34C has a max power handling value of 100 watts RMS, 200 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
Platinum C250 3G features Binding post posts which make bi-amping or bi-wiring possible. R-34C has a Binding post which doesn't feature bi-amping/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 Klipsch R-34C'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 Klipsch R-34C has external dimensions of 126.0 x 662.0 x 159.0mm ( 4-15/16 x 26-1/16 x 6-1/4inch) .
Klipsch R-34C is 99mm shorter and 167mm less deeper than Monitor Audio Platinum C250 3G but it is also 32mm 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 Klipsch R-34C is approximately 1052.6cm2 / 163.2inch2. The Platinum C250 3G requires 95% more surface area than the R-34C 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 C250 3G weighs 25.40kg / 55.9lbs and the Klipsch R-34C weighs 5.91kg / 13lbs. This makes the Platinum C250 3G 330% heavier than the R-34C.
Here is a comparison of how Platinum C250 3G and R-34C's weights compare with the average, max and min weights in Passive Center Channel class.
