In this review, we will be comparing Motion XT F100 and RP-8000F II, two Passive Floor-standing speakers from MartinLogan and Klipsch. Let's have a brief look at the main features
of MartinLogan Motion XT F100 and Klipsch RP-8000F II first before getting into our more
detailed comparison.
What size room are the MartinLogan Motion XT F100 and Klipsch RP-8000F II 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 MartinLogan Motion XT F100 and Klipsch RP-8000F II 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 Motion XT F100 is a 3-way design whereas the RP-8000F II is a 2-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.

Motion XT F100 features a 1.25 x 2.4" Folded Motion XT Tweeter , a 6.5" Midrange and 3 x 6.5" Aluminum Woofer with a Crossover frequency at 280Hz and 2600Hz. 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
Motion XT F100 has a frequency range of 31-25k Hz whereas RP-8000F II has a frequency range of 32-25k Hz. With a minimum frequency of 31Hz, the Motion XT F100 can go slightly deeper then the RP-8000F II's min frequency of 32Hz.
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
Motion XT F100 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 Motion XT F100 can provide this impedance level.
These two speakers also have different sensitivity levels. Motion XT F100 sensitivity is rated at 92 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 MartinLogan Motion XT F100, 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.
Motion XT F100 can handle a max power of 450 watts RMS from the amp the whereas RP-8000F II has a max power handling value of 150 watts RMS, 300 watts less than the Motion XT F100.
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 Motion XT F100 and RP-8000F II features dual binding post speaker terminals for bi-amping or bi-wiring.
MartinLogan Motion XT F100's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
Klipsch RP-8000F II's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Motion XT F100 has a bottom firing port whereas RP-8000F II has a rear firing ports. MartinLogan Motion XT F100's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Klipsch RP-8000F II with its rear-firing port.
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 MartinLogan Motion XT F100's and Klipsch RP-8000F II's external dimensions. MartinLogan Motion XT F100 has external dimensions of 1213 x 318 x 381mm ( 47-3/4inch x 12-1/2inch x 15inch ) 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 41mm narrower and 116mm shorter than MartinLogan Motion XT F100 but it is also 66mm 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 MartinLogan Motion XT F100 is approximately 1211.6cm2 / 187.8inch2 and base area of the Klipsch RP-8000F II is approximately 1238.2cm2 / 191.9inch2. The Motion XT F100 requires 2% 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 MartinLogan Motion XT F100 weighs 34.50kg / 75.9lbs and the Klipsch RP-8000F II weighs 28.00kg / 61.6lbs. This makes the Motion XT F100 23% heavier than the RP-8000F II.
Here is a comparison of how Motion XT F100 and RP-8000F II's weights compare with the average, max and min weights in Passive Floor-standing class.
