In this review, we will be comparing SX-60 and RP-600M, two Passive Bookshelf speakers from Cambridge Audio and Klipsch. Let's have a brief look at the main features
of Cambridge SX-60 and Klipsch RP-600M first before getting into our more
detailed comparison.
What size room are the Cambridge SX-60 and Klipsch RP-600M 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:
In the following sections, we will get into more detail in order to better understand how the Cambridge SX-60 and Klipsch RP-600M 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-600M features a 1" Tractrix Horn Tweeter and 1 x 6.5" Cerametallic Woofer with a Crossover frequency at 1500Hz.
Frequency Response
SX-60 has a frequency range of 41-22k Hz whereas RP-600M has a frequency range of 45-25k Hz. With a minimum frequency of 41Hz, the SX-60 can go slightly deeper then the RP-600M's min frequency of 45Hz.
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
SX-60 and RP-600M 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-600M's is at 96 dB. This 7 dB difference makes the Klipsch RP-600M 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.
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. SX-60 has a Post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
SX-60 has a front firing port whereas RP-600M 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-600M 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-600M'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-600M has external dimensions of 399.0 x 202.0 x 301.0mm ( 15.7 x 7.9 x 11.8inch) .
Below you can see the front view size comparison of Cambridge SX-60 and Klipsch RP-600M 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-600M is approximately 608.0cm2 / 94.2inch2. The SX-60 requires 8% less surface area than the RP-600M which gives it a small advantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Cambridge SX-60 weighs 5.00kg / 11lbs and the Klipsch RP-600M weighs 7.30kg / 16.1lbs. This makes the RP-600M 46% heavier than the SX-60.
Here is a comparison of how SX-60 and RP-600M's weights compare with the average, max and min weights in Passive Bookshelf class.
