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 DM40 is a 4 ohms speaker compared to the RP-8000F II 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 DM40 can provide this impedance level.
These two speakers also have different sensitivity levels. Dymension DM40 sensitivity is rated at 87 dB and the RP-8000F II's is rated at 98 dB. This 11 dB difference makes the Klipsch RP-8000F II a more sensitive speaker compared to Definitive Dymension DM40, 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 DM40 can handle a max power of 250 watts RMS from the amp the whereas RP-8000F II has a max power handling value of 150 watts RMS, 100 watts less than the Dymension DM40.
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-8000F II features Binding post posts which make bi-amping or bi-wiring possible. Dymension DM40 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 Definitive Dymension DM40's and Klipsch RP-8000F II's external dimensions. Definitive Dymension DM40 has external dimensions of 950 x 261 x 255 mm ( 37.4 x 10.3 x 10.0 in) whereas Klipsch RP-8000F II has external dimensions of 1097.0 x 277.0 x 447.0mm ( 43-3/16 x 10-7/8 x 17-9/16inch) .
Klipsch RP-8000F II is clearly the larger of the two speakers. Its body is 16mm wider, 147mm taller and 192mm deeper than Definitive Dymension DM40.
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 DM40 is approximately 665.6cm2 / 103.2inch2 and base area of the Klipsch RP-8000F II is approximately 1238.2cm2 / 191.9inch2. The Dymension DM40 requires 46% less surface area than the RP-8000F II which gives it a small advantage on placement in tight spaces.
