             What size room are the JBL Studio 6 88LCR                and JBL Studio 690 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
        
            Studio 6 88LCR and  Studio 690 have the same Impedance of 6 ohms  but where they differ is the sensitivity levels. Studio 6 88LCR sensitivity is rated at  96 dB and the Studio 690's is at 90 dB.  This 6 dB difference makes the JBL Studio 6 88LCR a more sensitive speaker compared to JBL Studio 690, 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.
            
Studio 6 88LCR can handle a max power of   250 watts RMS from the amp the whereas Studio 6 88LCR has a max power handling value of 175 watts RMS , 75 watts less than the Studio 690.             
            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
        Studio 690 features 5-Way post posts which make bi-amping or bi-wiring possible. Studio 6 88LCR has a Spring posts which doesn't feature bi-amping/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 JBL Studio 6 88LCR's and JBL Studio 690's external dimensions. JBL Studio 6 88LCR has external dimensions of 520.0 x 223.0 x 96.0mm ( 20.4375-inch x 8.7500-inch x 3.7500-inch)  whereas JBL Studio 690 has external dimensions of 1096.0 x 299.0 x 383.0mm ( 43-1/8-inch x 11-3/4-inch x 15-1/16-inch) .
 JBL Studio 690 is clearly the larger of the two speakers. Its body is 76mm wider, 576mm taller and 287mm deeper than JBL Studio 6 88LCR.
