In this review, we will be comparing two different type of speakers . KLH Model Five is a  Floor-standing speaker  whereas the L100 Classic is a  Bookshelf speaker.
         
            Let's have a brief look at the main features
            of KLH Model Five and JBL L100 Classic first before getting into our more
            detailed comparison.

             What size room are the KLH Model Five                and JBL L100 Classic 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
        
            Model Five is a  6 ohms speaker compared to the L100 Classic which has a nominal impedance of 4 ohms.  Lower  impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the L100 Classic can provide this impedance level. 
These two speakers also have different sensitivity levels. Model Five sensitivity is rated at  90.5 dB and the L100 Classic's is rated at 90 dB.  This 1 dB difference makes the KLH Model Five a more sensitive speaker compared to JBL L100 Classic, 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
        Model Five features Five-way gold-plated binding posts type posts and L100 Classic has a Five-way gold-plated binding posts type posts. None of these speakers 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 KLH Model Five's and JBL L100 Classic's external dimensions. KLH Model Five has external dimensions of 660.0 x 350.0 x 292.0mm ( 34-1/4 x 13-3/4 x 13inch)  whereas JBL L100 Classic has external dimensions of 636.5 x 389.6 x 371.5mm ( 25.0 x 15.3 x 14.6inch) .
 KLH Model Five is 39.6mm narrower and 79.5mm less deeper than JBL L100 Classic but it is also 23.5mm 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 KLH Model Five is approximately 1022.0cm2 / 158.4inch2 and          base area of the JBL L100 Classic is approximately 1447.4cm2 / 224.3inch2.         The Model Five requires 29% less surface area than the L100 Classic which gives it a small advantage on placement in tight spaces.
