             What size room are the Revel M126Be                and Klipsch RP-600M 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:

                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 Revel M126Be and Klipsch RP-600M compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

         M126Be features a 1" beryllium Hard-Dome Tweeter  and 1 x 6.5" DCC Aluminum 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
        
            M126Be has a frequency range of   54-44k 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 M126Be's min frequency of 54Hz. 
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
        
            M126Be and  RP-600M have the same Impedance of 8 ohms  but where they differ is the sensitivity levels. M126Be sensitivity is rated at  86 dB and the RP-600M's is at 96 dB.  This 10 dB difference makes the Klipsch RP-600M a more sensitive speaker compared to Revel M126Be, 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.
            
M126Be can handle a max power of   150 watts RMS from the amp the whereas RP-600M has a max power handling value of 100 watts RMS, 50 watts less than the M126Be.             
            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. M126Be has a Binding post which doesn't feature bi-amping/bi-wiring.

             Cabinet Type and Port Position
        
            Both M126Be 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 M126Be's and Klipsch RP-600M's external dimensions. Revel M126Be has external dimensions of 388.0 x 212.0 x 262.0mm ( 15-1/4 x 8-5/16 x 10-5/16inch)  whereas Klipsch RP-600M has external dimensions of 399.0 x 202.0 x 301.0mm ( 15.7 x 7.9 x 11.8inch) .
 Revel M126Be is 11mm shorter and 39mm less deeper than Klipsch RP-600M but it is also 10mm wider. 
    
        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 M126Be is approximately 555.4cm2 / 86.1inch2 and          base area of the Klipsch RP-600M is approximately 608.0cm2 / 94.2inch2.         The M126Be requires 9% less surface area than the RP-600M which gives it a small advantage on placement in tight spaces.      
 
        
        
        
        
        
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 Revel M126Be weighs 10.00kg / 22lbs and the Klipsch RP-600M weighs 7.30kg / 16.1lbs. This makes the M126Be 37% heavier than the RP-600M. 
Here is a comparison of how M126Be and RP-600M's weights compare with the average, max and min weights in Passive Bookshelf class.
