In this review, we will be comparing Lumina V and R700, two Passive Floor-standing speakers from Sonus Faber and Polk Audio. Let's have a brief look at the main features
of Sonus Lumina V and Polk R700 first before getting into our more
detailed comparison.
What size room are the Sonus Lumina V and Polk R700 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 V and Polk R700 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Lumina V features a 1.15" high definition DAD Tweeter , a 6" Midrange and 2 x 6.5" paper cone Woofer with a Crossover frequency at 260 and 2600 Hz. On the other hand, the R700 features a 1" Pinnacle Ring Radiator Tweeter , a 6.5" Midrange and 2 x 8" Polypropylene Woofer with a Crossover frequency at 350Hz and 2700Hz.
Frequency Response
Lumina V has a frequency range of 38-24k Hz whereas R700 has a frequency range of 38-38k Hz.
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 V is a 4 ohms speaker compared to the R700 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 V can provide this impedance level.
These two speakers also have different sensitivity levels. Lumina V sensitivity is rated at 90 dB and the R700's is rated at 88 dB. This 2 dB difference makes the Sonus Lumina V a more sensitive speaker compared to Polk R700, 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 V and R700 has the same power range of 50-300 watts.
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
Both Lumina V and R700 features dual binding post speaker terminals for bi-amping or bi-wiring.
Polk R700's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Lumina V and R700 have bottom firing ports.

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 V's and Polk R700's external dimensions. Sonus Lumina V has external dimensions of 1049.0 x 280.0 x 373.0mm ( 41.3 x 11 x 14.7inch) whereas Polk R700 has external dimensions of 1143.8 x 320.7 x 428.3mm ( 45 x 12.6 x 16.9inch) .
Polk R700 is clearly the larger of the two speakers. Its body is 40.7mm wider, 94.8mm taller and 55.3mm deeper than Sonus Lumina V.
Below you can see the front view size comparison of Sonus Lumina V and Polk R700 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 V is approximately 1044.4cm2 / 161.9inch2 and base area of the Polk R700 is approximately 1373.6cm2 / 212.9inch2. The Lumina V requires 24% less surface area than the R700 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 V weighs 22.50kg / 49.5lbs and the Polk R700 weighs 35.90kg / 79lbs. This makes the R700 60% heavier than the Lumina V.
