M8 SP2 features a 1" MCC (Micro Ceramic Composite) Hard-Dome Tweeter and 2 x 3" Micro Ceramic Composite Woofer . On the other hand, the RP-600M features a 1" Tractrix Horn Tweeter and 1 x 6.5" Cerametallic Woofer with a Crossover frequency at 1500Hz.
Frequency Response
M8 SP2 has a frequency range of 110-21k Hz whereas RP-600M has a frequency range of 45-25k Hz. With a minimum frequency of 45Hz, the RP-600M can go significantly deeper on the low side and provide stronger bass compared to the M8 SP2's min frequency of 110Hz.
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 On-wall 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
M8 SP2 and RP-600M have the same Impedance of 8 ohms but where they differ is the sensitivity levels. M8 SP2 sensitivity is rated at 88 dB and the RP-600M's is at 96 dB. This 8 dB difference makes the Klipsch RP-600M a more sensitive speaker compared to Revel M8 SP2, 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.
M8 SP2 can handle a max power of 125 watts RMS from the amp the whereas RP-600M has a max power handling value of 100 watts RMS, 25 watts less than the M8 SP2.
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-600M features Dual binding posts/bi-wire/bi-amp posts which make bi-amping or bi-wiring possible. M8 SP2 has a 5-way post which doesn't feature bi-amping/bi-wiring.
Klipsch RP-600M's Dual binding posts/bi-wire/bi-amp terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both M8 SP2 and RP-600M 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 Revel M8 SP2's and Klipsch RP-600M's external dimensions. Revel M8 SP2 has external dimensions of 297.0 x 108.0 x 118.0mm ( 11-11/16 x 4-1/4 x 4-5/8inch) whereas Klipsch RP-600M has external dimensions of 399.0 x 202.0 x 301.0mm ( 15.7 x 7.9 x 11.8inch) .
Klipsch RP-600M is clearly the larger of the two speakers. Its body is 94mm wider, 102mm taller and 183mm deeper than Revel M8 SP2.
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 Revel M8 SP2 is approximately 127.4cm2 / 19.7inch2 and base area of the Klipsch RP-600M is approximately 608.0cm2 / 94.2inch2. The M8 SP2 requires 79% less surface area than the RP-600M which gives it a small advantage on placement in tight spaces.
