In this review, we will be comparing Sib-T and RP-500M, two Passive Bookshelf speakers from Focal and Klipsch. Let's have a brief look at the main features
of Focal Sib-T and Klipsch RP-500M first before getting into our more
detailed comparison.
In the following sections, we will get into more detail in order to better understand how the Focal Sib-T 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.

Sib-T features a .75" Dome Tweeter and 1 x 5.125" Polyflex 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
Sib-T has a frequency range of 80-20kHz whereas RP-500M has a frequency range of 48-25k Hz. With a minimum frequency of 48Hz, the RP-500M can go significantly deeper on the low side and provide stronger bass compared to the Sib-T's min frequency of 80Hz.
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-T is a 4 ohms speaker compared to the RP-500M which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Sib-T can provide this impedance level.
These two speakers also have different sensitivity levels. Sib-T sensitivity is rated at 90 dB and the RP-500M's is rated at 93 dB. This 3 dB difference makes the Klipsch RP-500M a more sensitive speaker compared to Focal Sib-T, hence will play louder with the same amount of watts.

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-T's and Klipsch RP-500M's external dimensions. Focal Sib-T has external dimensions of 64.0 x 143.0 x 170.0mm ( 2-1/2 x 5-5/8 x 6-11/16inch) 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 clearly the larger of the two speakers. Its body is 30mm wider, 279mm taller and 71mm deeper than Focal Sib-T.
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-T is approximately 243.1cm2 / 37.7inch2 and base area of the Klipsch RP-500M is approximately 416.9cm2 / 64.6inch2. The Sib-T requires 42% less surface area than the RP-500M 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-T weighs 2.60kg / 5.7lbs and the Klipsch RP-500M weighs 5.40kg / 11.9lbs. This makes the RP-500M 108% heavier than the Sib-T.
Here is a comparison of how Sib-T and RP-500M's weights compare with the average, max and min weights in Passive Bookshelf class.
