             What size room are the Klipsch RP-600M                and Polk TSi100 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:

             (* Approximate Room sizes: Small < 100sq. ft / 9 m2,
                Mid-size: 100-220 sq. ft / 9-20 m2, Large 220-400 sq. ft / 20-36 m2, Very Large: >
                400 sq. ft / 36 m2.
                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 Klipsch RP-600M and Polk TSi100 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

         RP-600M features a 1"  Tractrix Horn Tweeter  and 1 x 6.5" Cerametallic Woofer  with a Crossover frequency at  1500Hz.  On the other hand, the TSi100 features a 1"  Dome Tweeter  and 1 x 5.25" Organic Fiber Woofer  with a Crossover frequency at  2500Hz. 
     
    
         Frequency Response
        
            RP-600M has a frequency range of   45-25k Hz whereas TSi100 has a frequency range of 61-24k Hz.  With a minimum frequency of 45Hz, the RP-600M can go significantly deeper on the low side and provide stronger bass compared to the TSi100's min frequency of 61Hz. 
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Bookshelf class in our database.

     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
        
            RP-600M and  TSi100 have the same Impedance of 8 ohms  but where they differ is the sensitivity levels. RP-600M sensitivity is rated at  96 dB and the TSi100's is at 89 dB.  This 7 dB difference makes the Klipsch RP-600M a more sensitive speaker compared to Polk TSi100, 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
        RP-600M features Dual binding posts/bi-wire/bi-amp posts which make bi-amping or bi-wiring possible. TSi100 has a Pair of 5-way Binding Posts - Gold-Plated which doesn't feature bi-amping/bi-wiring.

             Cabinet Type and Port Position
        
            Both RP-600M and  TSi100 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and  front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
 If you are limited in space and can't get the speakers away from the backwall, check our  Speakers with Front Firing Ports page.

 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 RP-600M's and Polk TSi100's external dimensions. Klipsch RP-600M has external dimensions of 399.0 x 202.0 x 301.0mm ( 15.7 x 7.9 x 11.8inch)  whereas Polk TSi100 has external dimensions of 279.4 x 177.8 x 259.0mm ( 11.0 x 7.0 x 10.1inch) .
 Klipsch RP-600M is clearly the larger of the two speakers. Its body is 24.2mm wider, 119.6mm taller and 42mm deeper than Polk TSi100.

        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 RP-600M is approximately 608.0cm2 / 94.2inch2 and          base area of the Polk TSi100 is approximately 460.5cm2 / 71.4inch2.         The RP-600M requires 32% more surface area than the TSi100 which gives it a small disadvantage on placement in tight spaces.
