Frequency Response
RP-6103M and RP-600M II has exactly the same frequency range of 44-25k Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
RP-6103M and RP-600M II have the same Impedance of 8 ohms and their sensitivity is also same at 94 dB.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
RP-6103M and RP-600M II have the same power range of up to 100 watts.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Both RP-6103M and RP-600M II features dual binding post speaker terminals for bi-amping or bi-wiring.
Klipsch RP-600M II's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both RP-6103M and RP-600M II 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
The size of a speaker can sometimes be 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-6103M's and Klipsch RP-600M II's external dimensions. Klipsch RP-6103M has external dimensions of 400.0 x 202.0 x 330.0mm (15-3/4 x 7-15/16 x 13inch) whereas Klipsch RP-600M II has external dimensions of 402.0 x 204.0 x 332.0mm (15-13/16 x 8 x 13-1/16inch).
Klipsch RP-600M II is clearly the larger of the two speakers. Its body is 2mm wider, 2mm taller and 2mm deeper than Klipsch RP-6103M.
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-6103M is approximately 666.6cm2 / 103.3inch2 and base area of the Klipsch RP-600M II is approximately 677.3cm2 / 105.0inch2. The RP-6103M requires 2% less surface area than the RP-600M II which gives it a small advantage on placement in tight spaces.
