RP-160M features a 1" Tractrix Horn Tweeter and 1 x 6.5" Cerametallic Woofer with a Crossover frequency at 1500Hz. On the other hand, the Motion LX16 features a 1.0 x 1.4" Folded Motion Tweeter and 1 x 5.25" Aluminum Woofer with a Crossover frequency at 2700Hz.
Frequency Response
RP-160M has a frequency range of 45-25k Hz whereas Motion LX16 has a frequency range of 60-25k Hz. With a minimum frequency of 45Hz, the RP-160M can go significantly deeper on the low side and provide stronger bass compared to the Motion LX16's min frequency of 60Hz.
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 Bookshelf class in our database.

High Frequency
Bookshelf 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
RP-160M is a 8 ohms speaker compared to the Motion LX16 which has a nominal impedance of 5 ohms.
These two speakers also have different sensitivity levels. RP-160M sensitivity is rated at 95 dB and the Motion LX16's is rated at 92 dB. This 3 dB difference makes the Klipsch RP-160M a more sensitive speaker compared to MartinLogan LX16, 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-160M can handle a max power of 200 watts RMS from the amp the whereas RP-160M has a max power handling value of 100 watts RMS , 100 watts less than the Motion LX16.
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-160M features Dual binding posts posts which make bi-amping or bi-wiring possible. Motion LX16 has a Custom 5-way binding posts which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both RP-160M and Motion LX16 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 Klipsch RP-160M's and MartinLogan LX16's external dimensions. Klipsch RP-160M has external dimensions of 424.0 x 224.0 x 327.0mm ( 16.6 x 8.8 x 12.8inch) whereas MartinLogan LX16 has external dimensions of 280.0 x 165.0 x 242.0mm ( 11.0 x 6.4 x 9.5inch) .
Klipsch RP-160M is clearly the larger of the two speakers. Its body is 59mm wider, 144mm taller and 85mm deeper than MartinLogan LX16.
Below you can see the front view size comparison of Klipsch RP-160M and MartinLogan LX16 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 Klipsch RP-160M is approximately 732.5cm2 / 113.5inch2 and base area of the MartinLogan LX16 is approximately 399.3cm2 / 61.9inch2. The RP-160M requires 83% more surface area than the Motion LX16 which gives it a small disadvantage on placement in tight spaces.
