In this review, we will be comparing Lumina III and R-625FA, two Passive Floor-standing speakers from Sonus Faber and Klipsch. Let's have a brief look at the main features
of Sonus Lumina III and Klipsch R-625FA first before getting into our more
detailed comparison.
What size room are the Sonus Lumina III and Klipsch R-625FA 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 Sonus Lumina III and Klipsch R-625FA compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Lumina III is a 3-way design whereas the R-625FA is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Lumina III features a 1.15" high definition DAD Tweeter , a 6" Midrange and 2 x 6" paper cone Woofer with a Crossover frequency at 350 and 3500 Hz. On the other hand, the R-625FA features a 1" Tweeter and 2 x 6.5" Copper-spun IMG Woofer with a Crossover frequency at 2000Hz.
Frequency Response
Lumina III has a frequency range of 40-24k Hz whereas R-625FA has a frequency range of 38-21k Hz. With a minimum frequency of 38Hz, the R-625FA can go slightly deeper then the Lumina III's min frequency of 40Hz.
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 Floor-standing class in our database.

High Frequency
Floor-standing 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
Lumina III is a 4 ohms speaker compared to the R-625FA 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 Lumina III can provide this impedance level.
These two speakers also have different sensitivity levels. Lumina III sensitivity is rated at 89 dB and the R-625FA's is rated at 96 dB. This 7 dB difference makes the Klipsch R-625FA a more sensitive speaker compared to Sonus Lumina III, 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.
Lumina III can handle a max power of 250 watts RMS from the amp the whereas R-625FA has a max power handling value of 100 watts RMS, 150 watts less than the Lumina III.
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
Lumina III features Binding post posts which make bi-amping or bi-wiring possible. R-625FA has a Post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Lumina III has a bottom firing port whereas R-625FA has a rear firing ports. Sonus Lumina III's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Klipsch R-625FA 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 Sonus Lumina III's and Klipsch R-625FA's external dimensions. Sonus Lumina III has external dimensions of 989.0 x 228.0 x 278.0mm ( 38.9 x 9 x 10.9inch) whereas Klipsch R-625FA has external dimensions of 1021.0 x 239.0 x 426.0mm ( 40-3/16 x 9-3/8 x 16-3/4inch) .
Klipsch R-625FA is clearly the larger of the two speakers. Its body is 11mm wider, 32mm taller and 148mm deeper than Sonus Lumina III.
Below you can see the front view size comparison of Sonus Lumina III and Klipsch R-625FA 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 Sonus Lumina III is approximately 633.8cm2 / 98.2inch2 and base area of the Klipsch R-625FA is approximately 1018.1cm2 / 157.8inch2. The Lumina III requires 38% less surface area than the R-625FA 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 Sonus Lumina III weighs 15.90kg / 35lbs and the Klipsch R-625FA weighs 22.20kg / 48.8lbs. This makes the R-625FA 40% heavier than the Lumina III.
Here is a comparison of how Lumina III and R-625FA's weights compare with the average, max and min weights in Passive Floor-standing class.
