             What size room are the Wharfedale Reva 1                and B&W 606 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 Wharfedale Reva 1 and B&W 606 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

     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
        
            Reva 1 and  BW 606 have the same Impedance of 8 ohms  but where they differ is the sensitivity levels. Reva 1 sensitivity is rated at  86 dB and the BW 606's is at 88 dB.  This 2 dB difference makes the B&W 606 a more sensitive speaker compared to Wharfedale Reva 1, 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.
            
Reva 1 can handle a max power of   120 watts RMS from the amp the whereas Reva 1 has a max power handling value of 60 watts RMS , 60 watts less than the BW 606.             
            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 Reva 1 and  BW 606 features dual binding post speaker terminals for bi-amping or bi-wiring.

             Cabinet Type and Port Position
        
            Reva 1 has a bottom firing port whereas BW 606 has a  rear firing ports. Wharfedale Reva 1's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to B&W 606 with its  rear-firing port.         
            
    
 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 Wharfedale Reva 1's and B&W 606's external dimensions. Wharfedale Reva 1 has external dimensions of 318.0 x 174.0 x 285.0mm ( 12-1/2 x 6-13/16 x 11-3/16inch)  whereas B&W 606 has external dimensions of 345.0 x 190.0 x 324.0mm ( 13.5 x 7.4 x 12.7inch) .
 B&W 606 is clearly the larger of the two speakers. Its body is 16mm wider, 27mm taller and 39mm deeper than Wharfedale Reva 1.

        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 Wharfedale Reva 1 is approximately 495.9cm2 / 76.9inch2 and          base area of the B&W 606 is approximately 615.6cm2 / 95.4inch2.         The Reva 1 requires 19% less surface area than the BW 606 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 Wharfedale Reva 1 weighs 5.64kg / 12.4lbs and the B&W 606 weighs 6.90kg / 15.2lbs. This makes the BW 606 22% heavier than the Reva 1. 
Here is a comparison of how Reva 1 and BW 606's weights compare with the average, max and min weights in Passive Bookshelf class.
