What size room are the Klipsch RP-600M and Klipsch RP-600M 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:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the Klipsch RP-600M and Klipsch RP-600M II compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

RP-600M features a 1" Tractrix Horn Tweeter and 1 x 6.5" Cerametallic Woofer with a Crossover frequency at 1500Hz. On the other hand, the RP-600M II features a 1" titanium Hybrid Tractrix Horn Tweeter and 1 x 6.5" Cerametallic cone Woofer with a Crossover frequency at 1500 Hz.
Frequency Response
RP-600M has a frequency range of 45-25k Hz whereas RP-600M II has a frequency range of 44-25k Hz. With a minimum frequency of 44Hz, the RP-600M II can go slightly deeper then the RP-600M's min frequency of 45Hz.
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.

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-600M and RP-600M II have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-600M sensitivity is rated at 96 dB and the RP-600M II's is at 94.5 dB. This 2 dB difference makes the Klipsch RP-600M a more sensitive speaker compared to Klipsch RP-600M II, 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-600M and RP-600M II has the same power range of up to 100 watts.
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 RP-600M and RP-600M II features dual binding post speaker terminals for bi-amping or bi-wiring.
Klipsch RP-600M's Dual binding posts/bi-wire/bi-amp terminals allows 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-600M 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
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-600M's and Klipsch RP-600M II's external dimensions. Klipsch RP-600M has external dimensions of 399.0 x 202.0 x 301.0mm ( 15.7 x 7.9 x 11.8inch) 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, 3mm taller and 31mm deeper than Klipsch RP-600M.
Below you can see the front view size comparison of Klipsch RP-600M and Klipsch RP-600M II 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-600M is approximately 608.0cm2 / 94.2inch2 and base area of the Klipsch RP-600M II is approximately 677.3cm2 / 105.0inch2. The RP-600M requires 10% less surface area than the RP-600M II which gives it a small advantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 Klipsch RP-600M weighs 7.30kg / 16.1lbs and the Klipsch RP-600M II weighs 8.20kg / 18lbs. This makes the RP-600M II 12% heavier than the RP-600M.
Here is a comparison of how RP-600M and RP-600M II's weights compare with the average, max and min weights in Passive Bookshelf class.
