What size room are the B&W 707 S2 and B&W 706 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:

Listening Environment*	B&W 707 S2	B&W 706 S2
Near-field	Average	Poor
Small Room	Good	Average
Mid-size Room	Average	Good
Large Room	Poor	Average
Very Large Room	Bad	Poor

(* Approximate Room sizes: Small < 100sq. ft / 9 m², Mid-size: 100-220 sq. ft / 9-20 m², Large 220-400 sq. ft / 20-36 m², Very Large: > 400 sq. ft / 36 m². 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.)

In the following sections, we will get into more detail in order to better understand how the B&W 707 S2 and B&W 706 S2 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

707 S2 features a 1" Decoupled Soft-Dome Tweeter and 1 x 5" Continuum Woofer . On the other hand, the 706 S2 features a 1" Decoupled Soft-Dome Tweeter and 1 x 6.5" Continuum Woofer .

Frequency Response

707 S2 and 706 S2 has exactly the same frequency range of 50-28k Hz.

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

707 S2 and 706 S2 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. 707 S2 sensitivity is rated at 84 dB and the 706 S2's is at 88 dB. This 4 dB difference makes the B&W 706 S2 a more sensitive speaker compared to B&W 707 S2, 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.

707 S2 can handle a max power of 120 watts RMS from the amp the whereas 707 S2 has a max power handling value of 100 watts RMS , 20 watts less than the 706 S2.

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

Both 707 S2 and 706 S2 features dual binding post speaker terminals for bi-amping or bi-wiring.

Cabinet Type and Port Position

Both 707 S2 and 706 S2 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 B&W 707 S2's and B&W 706 S2's external dimensions. B&W 707 S2 has external dimensions of 280.0 x 165.0 x 276.0mm ( 11-inch x 6.5-inch x 10.9-inch) whereas B&W 706 S2 has external dimensions of 340.0 x 200.0 x 301.0mm ( 13.5-inch x 7.8-inch x 11.-inch) .

B&W 706 S2 is clearly the larger of the two speakers. Its body is 35mm wider, 60mm taller and 25mm deeper than B&W 707 S2.

Below you can see the front view size comparison of B&W 707 S2 and B&W 706 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 707 S2 is approximately 455.4cm² / 70.6inch² and base area of the B&W 706 S2 is approximately 602.0cm² / 93.3inch². The 707 S2 requires 24% less surface area than the 706 S2 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 B&W 707 S2 weighs 6.00kg / 13.2lbs and the B&W 706 S2 weighs 8.05kg / 17.7lbs. This makes the 706 S2 34% heavier than the 707 S2.

Here is a comparison of how 707 S2 and 706 S2's weights compare with the average, max and min weights in Passive Bookshelf class.
