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.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. 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.
Sensitivity
Floor-standing Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
R700 can handle a max power of 300 watts RMS, whereas Prime Tower has a max power handling value of 250 watts RMS, 50 watts less than the R700.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.

Starting with a popular amplifier — change it to the one you own, or any you are
considering, and watch both numbers move.
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
The size of a speaker can sometimes be 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.

A generation apart: Polk R700 is the newer design, against a 2015 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass |
A |
SVS Prime Tower digs deeper - 30Hz against 38Hz. A subwoofer would even that out. |
| Amplifier needs |
evenly matched |
Similar sensitivity (87dB vs 88dB) - both want much the same power. |
| Headroom |
evenly matched |
Similar power handling (250W vs 300W). |
| Size |
depends |
SVS Prime Tower is easier to place; Polk R700 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability |
B |
Polk R700: bi-amping. |
| Price |
A |
SVS Prime Tower is cheaper - $1,400 against $2,198, about 36% less. |
A SVS Prime Tower
B Polk R700
depends neither is better in the abstract - it turns on your room, placement or how you will use them.
Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 38Hz anyway, so judge these on the other rows instead. In a large or open-plan room, Polk R700 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, SVS Prime Tower is the easier speaker to get right.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
