What size room are the Cambridge SX-60 and Klipsch RP-500M 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 Cambridge SX-60 and Klipsch RP-500M compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

SX-60 features a 1" Silk Soft-Dome Tweeter and 1 x 6.5" Treated paper Woofer . On the other hand, the RP-500M features a 1" Tractrix Horn Tweeter and 1 x 5.25" Cerametallic Woofer with a Crossover frequency at 1500Hz.
Frequency Response
SX-60 has a frequency range of 41-22k Hz whereas RP-500M has a frequency range of 48-25k Hz. With a minimum frequency of 41Hz, the SX-60 can go significantly deeper on the low side and provide stronger bass compared to the RP-500M's min frequency of 48Hz.
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
Bookshelf Speakers
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
SX-60 and RP-500M have the same Impedance of 8 ohms but where they differ is the sensitivity levels. SX-60 sensitivity is rated at 89 dB and the RP-500M's is at 93 dB. This 4 dB difference makes the Klipsch RP-500M a more sensitive speaker compared to Cambridge SX-60, 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.
SX-60 can handle a max power of 100 watts RMS from the amp the whereas RP-500M has a max power handling value of 75 watts RMS, 25 watts less than the SX-60.
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
SX-60 features Single binding posts type posts and RP-500M has a Single binding posts type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
SX-60 has a front firing port whereas RP-500M has a rear firing ports. Cambridge SX-60's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Klipsch RP-500M 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 Cambridge SX-60's and Klipsch RP-500M's external dimensions. Cambridge SX-60 has external dimensions of 342.0 x 202.0 x 277.0mm ( 13-7/16 x 7-15/16 x 10-7/8inch) whereas Klipsch RP-500M has external dimensions of 343.0 x 173.0 x 241.0mm ( 13.5 x 6.8 x 9.4inch) .
Klipsch RP-500M is 29mm narrower and 36mm less deeper than Cambridge SX-60 but it is also 1mm taller.
Below you can see the front view size comparison of Cambridge SX-60 and Klipsch RP-500M 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 Cambridge SX-60 is approximately 559.5cm2 / 86.7inch2 and base area of the Klipsch RP-500M is approximately 416.9cm2 / 64.6inch2. The SX-60 requires 34% more surface area than the RP-500M which gives it a small disadvantage on placement in tight spaces.
