Motion 60XTi features a 1.25 x 2.4" Folded Motion XT Tweeter , a 6.5" Midrange and 2 x 8" Aluminum Woofer with a Crossover frequency at 400Hz and 2200Hz. On the other hand, the R700 features a 1" Pinnacle Ring Radiator Tweeter , a 6.5" Midrange and 2 x 8" Polypropylene Woofer with a Crossover frequency at 350Hz and 2700Hz.
Frequency Response
Motion 60XTi has a frequency range of 35-25k Hz whereas R700 has a frequency range of 38-38k Hz. With a minimum frequency of 35Hz, the Motion 60XTi can go slightly deeper then the R700's min frequency of 38Hz.
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.

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
Motion 60XTi is a 4 ohms speaker compared to the R700 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 60XTi can provide this impedance level.
These two speakers also have different sensitivity levels. Motion 60XTi sensitivity is rated at 94 dB and the R700's is rated at 88 dB. This 6 dB difference makes the MartinLogan 60XTi a more sensitive speaker compared to Polk R700, 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 60XTi can handle a max power of 400 watts RMS from the amp the whereas R700 has a max power handling value of 300 watts RMS, 100 watts less than the Motion 60XTi.
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 60XTi and R700 features dual binding post speaker terminals for bi-amping or bi-wiring.
MartinLogan 60XTi's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
Polk R700's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Motion 60XTi has a rear firing port whereas R700 has a bottom firing ports. Polk R700's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to MartinLogan 60XTi 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 60XTi's and Polk R700's external dimensions. MartinLogan 60XTi has external dimensions of 1174.0 x 231.0 x 396.0mm ( 46-3/16 x 9-1/16 x 15-9/16inch) whereas Polk R700 has external dimensions of 1143.8 x 320.7 x 428.3mm ( 45 x 12.6 x 16.9inch) .
MartinLogan 60XTi is 89.7mm narrower and 32.3mm less deeper than Polk R700 but it is also 30.2mm taller.
Below you can see the front view size comparison of MartinLogan 60XTi and Polk R700 in scale.

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 60XTi is approximately 914.8cm2 / 141.8inch2 and base area of the Polk R700 is approximately 1373.6cm2 / 212.9inch2. The Motion 60XTi requires 33% less surface area than the R700 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 60XTi weighs 30.00kg / 66lbs and the Polk R700 weighs 35.90kg / 79lbs. This makes the R700 20% heavier than the Motion 60XTi.
Here is a comparison of how Motion 60XTi and R700's weights compare with the average, max and min weights in Passive Floor-standing class.
