Frequency Response
Demand D11 has a frequency range of 61-22k Hz whereas RP-600M has a frequency range of 45-25k Hz. With a minimum frequency of 45Hz, the RP-600M can go significantly deeper on the low side and provide stronger bass compared to the Demand D11's min frequency of 61Hz.
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
Demand D11 and RP-600M have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Demand D11 sensitivity is rated at 90 dB and the RP-600M's is at 96 dB. This 6 dB difference makes the Klipsch RP-600M a more sensitive speaker compared to Definitive Demand D11, 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.
Demand D11 can handle a max power of 200 watts RMS from the amp the whereas RP-600M has a max power handling value of 100 watts RMS, 100 watts less than the Demand D11.
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 Demand D11 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

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 Demand D11's and Klipsch RP-600M's external dimensions. Definitive Demand D11 has external dimensions of 332.0 x 186.0 x 329.0mm ( 13-1/16 x 7-5/16 x 12-15/16inch) whereas Klipsch RP-600M has external dimensions of 399.0 x 202.0 x 301.0mm ( 15.7 x 7.9 x 11.8inch) .
Definitive Demand D11 is 16mm narrower and 67mm shorter than Klipsch RP-600M but it is also 28mm deeper.
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 Demand D11 is approximately 611.9cm2 / 94.8inch2 and base area of the Klipsch RP-600M is approximately 608.0cm2 / 94.2inch2. The Demand D11 requires 1% more surface area than the RP-600M 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 Demand D11 weighs 8.64kg / 19lbs and the Klipsch RP-600M weighs 7.30kg / 16.1lbs. This makes the Demand D11 18% heavier than the RP-600M.
Here is a comparison of how Demand D11 and RP-600M's weights compare with the average, max and min weights in Passive Bookshelf class.
