of SVS Prime Bookshelf and B&W 606 first before getting into our more
detailed comparison.
What size room are the SVS Prime Bookshelf and B&W 606 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 Bookshelf and B&W 606 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Prime Bookshelf features a 1" aluminum Hard-Dome Tweeter and 1 x 6.5" Woofer with a Crossover frequency at 2300Hz. On the other hand, the BW 606 features a 1" Decoupled Carbon Hard-Dome Tweeter and 1 x 6.5" Continuum Woofer .
Frequency Response
Prime Bookshelf has a frequency range of 48-25k Hz whereas BW 606 has a frequency range of 52-28k Hz. With a minimum frequency of 48Hz, the Prime Bookshelf can go slightly deeper then the BW 606's min frequency of 52Hz.
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 Bookshelf 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 Bookshelf and BW 606 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Prime Bookshelf sensitivity is rated at 87 dB and the BW 606's is at 88 dB. This 1 dB difference makes the B&W 606 a more sensitive speaker compared to SVS Prime Bookshelf, 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 Bookshelf can handle a max power of 150 watts RMS from the amp the whereas BW 606 has a max power handling value of 120 watts RMS, 30 watts less than the Prime Bookshelf.
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 606 features Post posts which make bi-amping or bi-wiring possible. Prime Bookshelf has a 5-way post which doesn't feature bi-amping/bi-wiring.

B&W 606's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Prime Bookshelf and BW 606 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 Bookshelf's and B&W 606's external dimensions. SVS Prime Bookshelf has external dimensions of 337.8 x 203.2 x 261.6mm ( 13.2 x 8.0 x 10.2inch) whereas B&W 606 has external dimensions of 345.0 x 190.0 x 324.0mm ( 13.5 x 7.4 x 12.7inch) .
SVS Prime Bookshelf is 7.2mm shorter and 62.4mm less deeper than B&W 606 but it is also 13.2mm wider.
Below you can see the front view size comparison of SVS Prime Bookshelf and B&W 606 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 Bookshelf is approximately 531.6cm2 / 82.4inch2 and base area of the B&W 606 is approximately 615.6cm2 / 95.4inch2. The Prime Bookshelf requires 14% less surface area than the BW 606 which gives it a small advantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 Bookshelf weighs 7.03kg / 15.5lbs and the B&W 606 weighs 6.90kg / 15.2lbs. This makes the Prime Bookshelf 2% heavier than the BW 606.
Here is a comparison of how Prime Bookshelf and BW 606's weights compare with the average, max and min weights in Passive Bookshelf class.
