What size room are the B&W 607 and B&W 607 S2 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 BW 607 and 607 S2 AE are 2-way speakers.

BW 607 features a 1" Decoupled Carbon Hard-Dome Tweeter and 1 x 5" Continuum Woofer. On the other hand, the 607 S2 AE features a 1" Aluminum Decoupled Double Dome Tweeter and 1 x 5" Continuum Woofer.
Frequency Response
BW 607 and 607 S2 AE has exactly the same frequency range of 52-28k Hz.
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
BW 607 and 607 S2 AE have the same Impedance of 8 ohms and their sensitivity is also same at 84 dB.
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.
BW 607 and 607 S2 AE have the same power range of 30-100 watts.
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
Both BW 607 and 607 S2 AE features dual binding post speaker terminals for bi-amping or bi-wiring.
B&W 607 S2's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both BW 607 and 607 S2 AE 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 B&W 607's and B&W 607 S2's external dimensions. B&W 607 has external dimensions of 300.0 x 165.0 x 207.0mm (11.8 x 6.4 x 8.1inch) whereas B&W 607 S2 has external dimensions of 301.0 x 166.0 x 232.0mm (11-13/16 x 6-1/2 x 9-1/8inch).
B&W 607 S2 is clearly the larger of the two speakers. Its body is 1mm wider, 1mm taller and 25mm deeper than B&W 607.
Below you can see the front view size comparison of B&W 607 and B&W 607 S2 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 607 is approximately 341.6cm2 / 52.9inch2 and base area of the B&W 607 S2 is approximately 385.1cm2 / 59.7inch2. The BW 607 requires 11% less surface area than the 607 S2 AE 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 B&W 607 weighs 4.70kg / 10.3lbs and the B&W 607 S2 weighs 4.70kg / 10.3lbs.
Here is a comparison of how BW 607 and 607 S2 AE's weights compare with the average, max and min weights in Passive Bookshelf class.

Both are Bowers Wilkins, from different ranges - so the house sound is shared and the differences are mostly in scale, engineering and price.
| Area | Better | Why |
|---|
| Bass | evenly matched | Much the same reach (52Hz vs 52Hz). |
| Amplifier needs | evenly matched | Similar sensitivity (84dB vs 84dB) - both want much the same power. |
| Headroom | evenly matched | Similar power handling (100W vs 100W). |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | B&W 607: bi-amping; B&W 607 S2: bi-amping. |
| Price | evenly matched | Much the same money ($799 vs $799 a pair). |
A B&W 607 B B&W 607 S2
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?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it.
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.
