Demand D7 features a 1" Hard-Dome Tweeter and 1 x 4.5" Polypropylene Woofer . 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
Demand D7 has a frequency range of 67-21k 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 D7's min frequency of 67Hz.
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 D7 and RP-600M have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Demand D7 sensitivity is rated at 85 dB and the RP-600M's is at 96 dB. This 11 dB difference makes the Klipsch RP-600M a more sensitive speaker compared to Definitive Demand D7, 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 D7 can handle a max power of 125 watts RMS from the amp the whereas RP-600M has a max power handling value of 100 watts RMS, 25 watts less than the Demand D7.
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
RP-600M features Dual binding posts/bi-wire/bi-amp posts which make bi-amping or bi-wiring possible. Demand D7 has a 5-Way 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 Definitive Demand D7's and Klipsch RP-600M's external dimensions. Definitive Demand D7 has external dimensions of 251.0 x 142.0 x 232.0mm ( 9-7/8 x 5-9/16 x 9-1/8inch) 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 clearly the larger of the two speakers. Its body is 60mm wider, 148mm taller and 69mm deeper than Definitive Demand D7.
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 D7 is approximately 329.4cm2 / 51.1inch2 and base area of the Klipsch RP-600M is approximately 608.0cm2 / 94.2inch2. The Demand D7 requires 46% less surface area than the RP-600M which gives it a small advantage on placement in tight spaces.
