In this review, we will be comparing Prime Pinnacle 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 Pinnacle and B&W 603 first before getting into our more
detailed comparison.
What size room are the SVS Prime Pinnacle 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 Pinnacle 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 Pinnacle features a 1" aluminum dome Tweeter , a 5.25" Midrange and 3 x 6.5" Polypropylene Woofer with a Crossover frequency at 300Hz 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 Pinnacle has a frequency range of 29-25k Hz whereas BW 603 has a frequency range of 48-28k Hz. With a minimum frequency of 29Hz, the Prime Pinnacle 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 Pinnacle and BW 603 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Prime Pinnacle sensitivity is rated at 88 dB and the BW 603's is at 88.5 dB. This 1 dB difference makes the B&W 603 a more sensitive speaker compared to SVS Prime Pinnacle, hence will play louder with the same amount of watts.

Floor-standing Speakers
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 Pinnacle can handle a max power of 300 watts RMS from the amp the whereas BW 603 has a max power handling value of 200 watts RMS, 100 watts less than the Prime Pinnacle.
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 Pinnacle has a 5-Way post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both Prime Pinnacle 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 Pinnacle's and B&W 603's external dimensions. SVS Prime Pinnacle has external dimensions of 1042.0 x 204.0 x 355.0mm ( 41 x 8 x 13-15/16inch) 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 Pinnacle is clearly the larger of the two speakers. Its body is 14mm wider, 57mm taller and 15mm deeper than B&W 603.
Below you can see the front view size comparison of SVS Prime Pinnacle 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 Pinnacle is approximately 724.2cm2 / 112.3inch2 and base area of the B&W 603 is approximately 646.0cm2 / 100.1inch2. The Prime Pinnacle requires 12% more surface area than the BW 603 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 SVS Prime Pinnacle weighs 25.95kg / 57.1lbs and the B&W 603 weighs 24.14kg / 53.1lbs. This makes the Prime Pinnacle 7% heavier than the BW 603.
