In this review, we will be comparing R700 and R-625FA, two Passive Floor-standing speakers from Polk Audio and Klipsch. Let's have a brief look at the main features
of Polk R700 and Klipsch R-625FA first before getting into our more
detailed comparison.
What size room are the Polk R700 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 Polk R700 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 R700 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.

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. 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
R700 has a frequency range of 38-38k Hz whereas R-625FA has a frequency range of 38-21k 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.

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
R700 and R-625FA have the same Impedance of 8 ohms but where they differ is the sensitivity levels. R700 sensitivity is rated at 88 dB and the R-625FA's is at 96 dB. This 8 dB difference makes the Klipsch R-625FA 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.
R700 can handle a max power of 300 watts RMS from the amp the whereas R-625FA has a max power handling value of 100 watts RMS, 200 watts less than the R700.
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
R700 features 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
R700 has a bottom firing port whereas R-625FA has a rear firing ports. Polk R700'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 Polk R700's and Klipsch R-625FA's external dimensions. Polk R700 has external dimensions of 1143.8 x 320.7 x 428.3mm ( 45 x 12.6 x 16.9inch) 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) .
Polk R700 is clearly the larger of the two speakers. Its body is 81.7mm wider, 122.8mm taller and 2.3mm deeper than Klipsch R-625FA.
Below you can see the front view size comparison of Polk R700 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 Polk R700 is approximately 1373.6cm2 / 212.9inch2 and base area of the Klipsch R-625FA is approximately 1018.1cm2 / 157.8inch2. The R700 requires 35% more surface area than the R-625FA which gives it a small disadvantage 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 Polk R700 weighs 35.90kg / 79lbs and the Klipsch R-625FA weighs 22.20kg / 48.8lbs. This makes the R700 62% heavier than the R-625FA.
