What size room are the Klipsch RP-500M 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 Klipsch RP-500M 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.

RP-500M features a 1" Tractrix Horn Tweeter and 1 x 5.25" Cerametallic Woofer with a Crossover frequency at 1500Hz. On the other hand, the BW 606 features a 1" Decoupled Carbon Hard-Dome Tweeter and 1 x 6.5" Continuum Woofer .
Frequency Response
RP-500M has a frequency range of 48-25k Hz whereas BW 606 has a frequency range of 52-28k Hz. With a minimum frequency of 48Hz, the RP-500M can go slightly deeper then the BW 606's min frequency of 52Hz.
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.

High Frequency

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-500M and BW 606 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-500M sensitivity is rated at 93 dB and the BW 606's is at 88 dB. This 5 dB difference makes the Klipsch RP-500M a more sensitive speaker compared to B&W 606, 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.
RP-500M can handle a max power of 120 watts RMS from the amp the whereas RP-500M has a max power handling value of 75 watts RMS , 45 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
BW 606 features Post posts which make bi-amping or bi-wiring possible. RP-500M has a Single binding posts which doesn't feature bi-amping/bi-wiring.

B&W 606's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both RP-500M and BW 606 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-500M's and B&W 606's external dimensions. Klipsch RP-500M has external dimensions of 343.0 x 173.0 x 241.0mm ( 13.5 x 6.8 x 9.4inch) 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 17mm wider, 2mm taller and 83mm deeper than Klipsch RP-500M.
Below you can see the front view size comparison of Klipsch RP-500M and B&W 606 in scale.

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-500M is approximately 416.9cm2 / 64.6inch2 and base area of the B&W 606 is approximately 615.6cm2 / 95.4inch2. The RP-500M requires 32% less surface area than the BW 606 which gives it a small advantage on placement in tight spaces.
