In this review, we will be comparing Sib Evo and RP-600M, two Passive Bookshelf speakers from Focal and Klipsch. Let's have a brief look at the main features
of Focal Sib Evo and Klipsch RP-600M first before getting into our more
detailed comparison.
What size room are the Focal Sib Evo 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 Focal Sib Evo 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.

Sib Evo features a 1" Soft-Dome Tweeter and 1 x 5" Polyflex 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
Sib Evo has a frequency range of 70-25k Hz whereas RP-600M has a frequency range of 45-25k 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 Sib Evo's min frequency of 70Hz.
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
Sib Evo is a 6 ohms speaker compared to the RP-600M which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Sib Evo sensitivity is rated at 90 dB and the RP-600M's is rated at 96 dB. This 6 dB difference makes the Klipsch RP-600M a more sensitive speaker compared to Focal Sib Evo, 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.
Sib Evo can handle a max power of 200 watts RMS from the amp the whereas RP-600M has a max power handling value of 100 watts RMS, 100 watts less than the Sib Evo.
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. Sib Evo has a Push button which doesn't feature bi-amping/bi-wiring.

Klipsch RP-600M's Dual binding posts/bi-wire/bi-amp terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Sib Evo and RP-600M 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 Focal Sib Evo's and Klipsch RP-600M's external dimensions. Focal Sib Evo has external dimensions of 251.0 x 162.0 x 164.0mm ( 28-36inch x 6-3/8inch x 6-7/16inch ) whereas Klipsch RP-600M has external dimensions of 399.0 x 202.0 x 301.0mm ( 15.7 x 7.9 x 11.8inch) .
Klipsch RP-600M is clearly the larger of the two speakers. Its body is 40mm wider, 148mm taller and 137mm deeper than Focal Sib Evo.
Below you can see the front view size comparison of Focal Sib Evo 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 Focal Sib Evo is approximately 265.7cm2 / 41.2inch2 and base area of the Klipsch RP-600M is approximately 608.0cm2 / 94.2inch2. The Sib Evo requires 56% less surface area than the RP-600M which gives it a small advantage on placement in tight spaces.
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 Focal Sib Evo weighs 1.80kg / 4lbs and the Klipsch RP-600M weighs 7.30kg / 16.1lbs. This makes the RP-600M 306% heavier than the Sib Evo.
Here is a comparison of how Sib Evo and RP-600M's weights compare with the average, max and min weights in Passive Bookshelf class.
