In this review, we will be comparing RP-8000F II and Demand D17, two Passive Floor-standing speakers from Klipsch and Definitive Technology. Let's have a brief look at the main features
of Klipsch RP-8000F II and Definitive Demand D17 first before getting into our more
detailed comparison.
What size room are the Klipsch RP-8000F II and Definitive Demand D17 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the Klipsch RP-8000F II and Definitive Demand D17 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that RP-8000F II is a 2-way design whereas the Demand D17 is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

RP-8000F II features a 1" titanium Tractrix Horn Tweeter and 2 x 8" Cerametallic cone Woofer with a Crossover frequency at 1630 Hz. On the other hand, the Demand D17 features a 1" aluminum dome Tweeter , a 6.5" Midrange and 2 x 6.5" Carbon-fiber Woofer .
Frequency Response
RP-8000F II has a frequency range of 32-25k Hz whereas Demand D17 has a frequency range of 42-22k 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 Demand D17's min frequency of 42Hz.
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.

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
RP-8000F II and Demand D17 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-8000F II sensitivity is rated at 98 dB and the Demand D17's is at 87 dB. This 11 dB difference makes the Klipsch RP-8000F II a more sensitive speaker compared to Definitive Demand D17, 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.
RP-8000F II can handle a max power of 300 watts RMS from the amp the whereas RP-8000F II has a max power handling value of 150 watts RMS , 150 watts less than the Demand D17.
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 RP-8000F II and Demand D17 features dual binding post speaker terminals for bi-amping or bi-wiring.
Klipsch RP-8000F II's Binding post terminals allows Bi-amping or bi-wiring
Definitive Demand D17's 5-Way Post 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 Klipsch RP-8000F II's and Definitive Demand D17's external dimensions. 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) whereas Definitive Demand D17 has external dimensions of 1086.0 x 261.0 x 375.0mm ( 42-3/4 x 10-1/4 x 14-3/4inch) .
Klipsch RP-8000F II is clearly the larger of the two speakers. Its body is 16mm wider, 11mm taller and 72mm deeper than Definitive Demand D17.
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 Klipsch RP-8000F II is approximately 1238.2cm2 / 191.9inch2 and base area of the Definitive Demand D17 is approximately 978.8cm2 / 151.7inch2. The RP-8000F II requires 27% more surface area than the Demand D17 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 Klipsch RP-8000F II weighs 28.00kg / 61.6lbs and the Definitive Demand D17 weighs 29.10kg / 64lbs. This makes the Demand D17 4% heavier than the RP-8000F II.
Here is a comparison of how RP-8000F II and Demand D17's weights compare with the average, max and min weights in Passive Floor-standing class.
