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:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
Both Prime Bookshelf and BW 606 are 2-way speakers.

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.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf 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 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.
Sensitivity
Bookshelf 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.
Prime Bookshelf can handle a max power of 150 watts RMS, whereas BW 606 has a max power handling value of 120 watts RMS, 30 watts less than the Prime Bookshelf.
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.
Which plays louder on your 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
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
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 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 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.

A generation apart: B&W 606 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 Bookshelf digs deeper - 48Hz against 52Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (87dB vs 88dB) - both want much the same power. |
| Headroom | A | SVS Prime Bookshelf takes more power (150W vs 120W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | B&W 606: bi-amping. SVS Prime Bookshelf sits in a wider range (8 models), so a matched surround system is easier later. |
| Price | A | SVS Prime Bookshelf is cheaper - $600 against $899, about 33% less. |
A SVS Prime Bookshelf B B&W 606
depends neither is better in the abstract - it turns on your room, your system 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?
SVS Prime Bookshelf is the easier recommendation: it leads on most of the measured areas and costs less. Take B&W 606 if its size, looks or fit in your room suit you better. Think about the whole system, not just the speakers: the roughly $299 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
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.
