             What size room are the ELAC Debut 2.0 B6.2                and B&W 706 S2 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:

     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
        
            Debut 2.0 B6.2 is a  6 ohms speaker compared to the 706 S2 which has a nominal impedance of 8 ohms.  
These two speakers also have different sensitivity levels. Debut 2.0 B6.2 sensitivity is rated at  87 dB and the 706 S2's is rated at 88 dB.  This 1 dB difference makes the B&W 706 S2 a more sensitive speaker compared to ELAC Debut 2.0 B6.2, 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
        706 S2 features Binding post posts which make bi-amping or bi-wiring possible. Debut 2.0 B6.2 has a 5-Way post which doesn't feature bi-amping/bi-wiring.

             Cabinet Type and Port Position
        
            Debut 2.0 B6.2 has a front firing port whereas 706 S2 has a  rear firing ports. ELAC Debut 2.0 B6.2's front-firing port gives more flexibility in placement in regards to proximity to walls compared to B&W 706 S2 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 ELAC Debut 2.0 B6.2's and B&W 706 S2's external dimensions. ELAC Debut 2.0 B6.2 has external dimensions of 375.0 x 195.0 x 268.0mm ( 14.7 x 7.6 x 10.5inch)  whereas B&W 706 S2 has external dimensions of 340.0 x 200.0 x 301.0mm ( 13.5-inch x 7.8-inch x 11.-inch) .
 ELAC Debut 2.0 B6.2 is 5mm narrower and 33mm less deeper than B&W 706 S2 but it is also 35mm taller.

        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 ELAC Debut 2.0 B6.2 is approximately 522.6cm2 / 81.0inch2 and          base area of the B&W 706 S2 is approximately 602.0cm2 / 93.3inch2.         The Debut 2.0 B6.2 requires 13% less surface area than the 706 S2 which gives it a small advantage on placement in tight spaces.
