Q Acoustics 5040 features a 1" Soft-dome Tweeter and 2 x 5" Continuous Curved Cone Woofer with a Crossover frequency at 2500 Hz. On the other hand, the RP-8000F II features a 1" titanium Tractrix Horn Tweeter and 2 x 8" Cerametallic cone Woofer with a Crossover frequency at 1630 Hz.
Frequency Response
Q Acoustics 5040 has a frequency range of 39-30k Hz whereas RP-8000F II has a frequency range of 32-25k Hz. With a minimum frequency of 32Hz, the RP-8000F II can go significantly deeper on the low side and provide stronger bass compared to the Q Acoustics 5040's min frequency of 39Hz.
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 Floor-standing class in our database.
Low Frequency

High Frequency
Floor-standing Speakers
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
Q Acoustics 5040 is a 6 ohms speaker compared to the RP-8000F II which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Q Acoustics 5040 sensitivity is rated at 91.5 dB and the RP-8000F II's is rated at 98 dB. This 6 dB difference makes the Klipsch RP-8000F II a more sensitive speaker compared to Q Acoustics 5040, 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.
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. Q Acoustics 5040 has a Binding post which doesn't feature bi-amping/bi-wiring.

Klipsch RP-8000F II's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Q Acoustics 5040 and RP-8000F II have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 Q Acoustics 5040's and Klipsch RP-8000F II's external dimensions. Q Acoustics 5040 has external dimensions of 969.0 x 362.0 x 293.0mm ( 38-1/8inch x 14-1/4inch x 11-1/2inch ) 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) .
Q Acoustics 5040 is 128mm shorter and 154mm less deeper than Klipsch RP-8000F II but it is also 85mm 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 Q Acoustics 5040 is approximately 1060.7cm2 / 164.4inch2 and base area of the Klipsch RP-8000F II is approximately 1238.2cm2 / 191.9inch2. The Q Acoustics 5040 requires 14% less surface area than the RP-8000F II which gives it a small advantage 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 Q Acoustics 5040 weighs 18.05kg / 39.7lbs and the Klipsch RP-8000F II weighs 28.00kg / 61.6lbs. This makes the RP-8000F II 55% heavier than the Q Acoustics 5040.
Here is a comparison of how Q Acoustics 5040 and RP-8000F II's weights compare with the average, max and min weights in Passive Floor-standing class.
