Prime Tower features a 1" aluminum dome Tweeter , a 4.5" Midrange and 2 x 6.5" Polypropylene Woofer with a Crossover frequency at 350Hz and 2100Hz. 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
Prime Tower has a frequency range of 30-25k Hz whereas R700 has a frequency range of 38-38k Hz. With a minimum frequency of 30Hz, the Prime Tower can go significantly deeper on the low side and provide stronger bass compared to the R700's min frequency of 38Hz.
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
Prime Tower and R700 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Prime Tower sensitivity is rated at 87 dB and the R700's is at 88 dB. This 1 dB difference makes the Polk R700 a more sensitive speaker compared to SVS Prime Tower, 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.
Prime Tower can handle a max power of 300 watts RMS from the amp the whereas Prime Tower has a max power handling value of 250 watts RMS , 50 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. Prime Tower has a 5-Way post which doesn't feature bi-amping/bi-wiring.

Polk R700's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Prime Tower has a rear firing port whereas R700 has a bottom firing ports. Polk R700's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to SVS Prime Tower 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 SVS Prime Tower's and Polk R700's external dimensions. SVS Prime Tower has external dimensions of 931.0 x 204.0 x 297.0mm ( 36-5/8 x 8 x 11-11/16inch) 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 116.7mm wider, 212.8mm taller and 131.3mm deeper than SVS Prime Tower.
Below you can see the front view size comparison of SVS Prime Tower 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 SVS Prime Tower is approximately 605.9cm2 / 93.9inch2 and base area of the Polk R700 is approximately 1373.6cm2 / 212.9inch2. The Prime Tower requires 56% 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 SVS Prime Tower weighs 18.23kg / 40.1lbs and the Polk R700 weighs 35.90kg / 79lbs. This makes the R700 97% heavier than the Prime Tower.
Here is a comparison of how Prime Tower and R700's weights compare with the average, max and min weights in Passive Floor-standing class.
