     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  M8 SP2 have the same Impedance of 8 ohms  and  their sensitivity is also same at 88 dB.

 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 and  M8 SP2 has the same power range of 10-125 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
        M8 SP2 features 5-way post type posts and M8 SP2 has a 5-way post type posts. None of these speakers feature bi-amping/bi-wiring.         
                        
        
    
             Cabinet Type and Port Position
        
            Both M8 SP2 and  M8 SP2 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 Revel M8 SP2'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 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) .
  In this case, we can see that Revel M8 SP2 and Revel M8 SP2 have the exact same height, width and thickness. 
    
        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 Revel M8 SP2 is approximately 127.4cm2 / 19.7inch2.             
 
        
        
        
        
        
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 M8 SP2 weighs 1.57kg / 3.5lbs and the Revel M8 SP2 weighs 1.57kg / 3.5lbs. 
Here is a comparison of how M8 SP2 and M8 SP2's weights compare with the average, max and min weights in Passive On-wall class.
