In this review, we will be comparing Prime Tower and BW 603, two Passive Floor-standing speakers from SVS and Bowers Wilkins. Let's have a brief look at the main features
of SVS Prime Tower and B&W 603 first before getting into our more
detailed comparison.
What size room are the SVS Prime Tower and B&W 603 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 SVS Prime Tower and B&W 603 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

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 BW 603 features a 1" Tweeter , a 6" Midrange and 2 x 6.5" Paper Woofer .
Frequency Response
Prime Tower has a frequency range of 30-25k Hz whereas BW 603 has a frequency range of 48-28k 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 BW 603's min frequency of 48Hz.
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

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 BW 603 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 BW 603's is at 88.5 dB. This 2 dB difference makes the B&W 603 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 250 watts RMS from the amp the whereas BW 603 has a max power handling value of 200 watts RMS, 50 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
BW 603 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.

Cabinet Type and Port Position
Both Prime Tower and BW 603 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 SVS Prime Tower's and B&W 603'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 B&W 603 has external dimensions of 985.0 x 190.0 x 340.0mm ( 38.7 x 7.4 x 13.3inch) .
SVS Prime Tower is 54mm shorter and 43mm less deeper than B&W 603 but it is also 14mm wider.
Below you can see the front view size comparison of SVS Prime Tower and B&W 603 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 B&W 603 is approximately 646.0cm2 / 100.1inch2. The Prime Tower requires 6% less surface area than the BW 603 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 B&W 603 weighs 24.14kg / 53.1lbs. This makes the BW 603 32% heavier than the Prime Tower.
