RP-404C features a 1" titanium Tractrix horn Tweeter and 4 x 4" Cerametallic cone Woofer . On the other hand, the RP-160M features a 1" Tractrix Horn Tweeter and 1 x 6.5" Cerametallic Woofer with a Crossover frequency at 1500Hz.
Frequency Response
RP-404C has a frequency range of 59-25k Hz whereas RP-160M has a frequency range of 45-25k 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 RP-404C's min frequency of 59Hz.
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 Center Channel class in our database.
Low Frequency
Center Channel Speakers
High Frequency
Center Channel 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-404C and RP-160M have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-404C sensitivity is rated at 97 dB and the RP-160M's is at 95 dB. This 2 dB difference makes the Klipsch RP-404C a more sensitive speaker compared to Klipsch RP-160M, 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-404C can handle a max power of 125 watts RMS from the amp the whereas RP-160M has a max power handling value of 100 watts RMS, 25 watts less than the RP-404C.
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. RP-404C has a Binding post which doesn't feature bi-amping/bi-wiring.

Klipsch RP-160M's Dual binding posts terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both RP-404C and RP-160M 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-404C's and Klipsch RP-160M's external dimensions. Klipsch RP-404C has external dimensions of 147.0 x 662.0 x 342.0mm ( 5-3/4 x 26-1/16 x 13-7/16inch) whereas Klipsch RP-160M has external dimensions of 424.0 x 224.0 x 327.0mm ( 16.6 x 8.8 x 12.8inch) .
Klipsch RP-160M is 438mm narrower and 15mm less deeper than Klipsch RP-404C but it is also 277mm taller.
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-404C is approximately 2264.0cm2 / 350.9inch2 and base area of the Klipsch RP-160M is approximately 732.5cm2 / 113.5inch2. The RP-404C requires 209% more surface area than the RP-160M which gives it a small disadvantage on placement in tight spaces.
