     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
        
            Cornwall IV and  Heresy III have the same Impedance of 8 ohms  but where they differ is the sensitivity levels. Cornwall IV sensitivity is rated at  102 dB and the Heresy III's is at 99 dB.  This 3 dB difference makes the Klipsch Cornwall IV a more sensitive speaker compared to Klipsch Heresy III, 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.
                        
            
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 Cornwall IV and  Heresy III features dual binding post speaker terminals for bi-amping or bi-wiring.         
                        
        
    
            
    
 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 Cornwall IV's and Klipsch Heresy III's external dimensions. Klipsch Cornwall IV has external dimensions of 966.0 x 643.0 x 394.0mm ( 38 x 25-5/16 x 15-1/2inch)  whereas Klipsch Heresy III has external dimensions of 607.0 x 394.0 x 342.0mm ( 23-7/8 x 15-1/2 x 13-7/16inch) .
 Klipsch Cornwall IV is clearly the larger of the two speakers. Its body is 249mm wider, 359mm taller and 52mm deeper than Klipsch Heresy III.

        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 Cornwall IV is approximately 2533.4cm2 / 392.7inch2 and          base area of the Klipsch Heresy III is approximately 1347.5cm2 / 208.9inch2.         The Cornwall IV requires 88% more surface area than the Heresy III which gives it a small disadvantage 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 Klipsch Cornwall IV weighs 44.55kg / 98lbs and the Klipsch Heresy III weighs 20.00kg / 44lbs. This makes the Cornwall IV 123% heavier than the Heresy III. 
Here is a comparison of how Cornwall IV and Heresy III's weights compare with the average, max and min weights in Passive Floor-standing class.
