704 S3 features a 1" Tweeter , a 5" Midrange and 2 x 5" Aerofoil Woofer . On the other hand, the 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.
Frequency Response
704 S3 has a frequency range of 46-28k Hz whereas Prime Tower has a frequency range of 30-25k 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 704 S3's min frequency of 46Hz.
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.
Low Frequency

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
704 S3 and Prime Tower have the same Impedance of 8 ohms but where they differ is the sensitivity levels. 704 S3 sensitivity is rated at 88 dB and the Prime Tower's is at 87 dB. This 1 dB difference makes the B&W 704 S3 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.
704 S3 can handle a max power of 250 watts RMS from the amp the whereas 704 S3 has a max power handling value of 150 watts RMS , 100 watts less than the Prime Tower.
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
704 S3 features Binding 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.
B&W 704 S3's Binding post terminals allows Bi-amping or bi-wiring
SVS Prime Tower's 5-Way post terminals
Cabinet Type and Port Position
Both 704 S3 and Prime Tower have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 B&W 704 S3's and SVS Prime Tower's external dimensions. B&W 704 S3 has external dimensions of 964.0 x 165.0 x 300.0mm ( 38-inch x 6.5-inch x 11.8-inch) whereas SVS Prime Tower has external dimensions of 931.0 x 204.0 x 297.0mm ( 36-5/8 x 8 x 11-11/16inch) .
SVS Prime Tower is 33mm shorter and 3mm less deeper than B&W 704 S3 but it is also 39mm wider.
Below you can see the front view size comparison of B&W 704 S3 and SVS Prime Tower 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 B&W 704 S3 is approximately 495.0cm2 / 76.7inch2 and base area of the SVS Prime Tower is approximately 605.9cm2 / 93.9inch2. The 704 S3 requires 18% less surface area than the Prime Tower which gives it a small advantage on placement in tight spaces.
