Dymension DM10 features a 1" aluminum oxide Hard-Dome Tweeter and 2 x 5.25" Polypropelene Woofer . On the other hand, the R-30C features a 1" LTS (Linear Travel Suspension) titanium diaphragm Tractrix Horn Tweeter and 4 x 3.5" spun-copper TCP Woofer with a Crossover frequency at 1650 Hz.
Frequency Response
Dymension DM10 has a frequency range of 81-23 kHz whereas R-30C has a frequency range of 78-21k Hz. With a minimum frequency of 78Hz, the R-30C can go slightly deeper then the Dymension DM10's min frequency of 81Hz.
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
Dymension DM10 is a 4 ohms speaker compared to the R-30C 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 Dymension DM10 can provide this impedance level.
These two speakers also have different sensitivity levels. Dymension DM10 sensitivity is rated at 90 dB and the R-30C's is rated at 96 dB. This 6 dB difference makes the Klipsch R-30C a more sensitive speaker compared to Definitive Dymension DM10, 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.
Dymension DM10 can handle a max power of 200 watts RMS from the amp the whereas R-30C has a max power handling value of 100 watts RMS, 100 watts less than the Dymension DM10.
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
Dymension DM10 features Binding post type posts and R-30C has a Binding post type posts. None of these speakers 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 Definitive Dymension DM10's and Klipsch R-30C's external dimensions. Definitive Dymension DM10 has external dimensions of 186 x 496 x 311 mm ( 7.3 x 19.5 x 12.2 in) whereas Klipsch R-30C has external dimensions of 126.0 x 662.0 x 174.0mm ( 4-15/16inch x 26-1/16inch x 6-13/16inch ) .
Klipsch R-30C is 60mm shorter and 137mm less deeper than Definitive Dymension DM10 but it is also 166mm 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 Definitive Dymension DM10 is approximately 1542.6cm2 / 239.1inch2 and base area of the Klipsch R-30C is approximately 1151.9cm2 / 178.5inch2. The Dymension DM10 requires 34% more surface area than the R-30C 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 Definitive Dymension DM10 weighs 13.20kg / 29lbs and the Klipsch R-30C weighs 5.00kg / 11lbs. This makes the Dymension DM10 164% heavier than the R-30C.
Here is a comparison of how Dymension DM10 and R-30C's weights compare with the average, max and min weights in Passive Center Channel class.
