In this review, we will be comparing Theva No1 and 606 S2 AE, two Passive Bookshelf speakers from Focal and Bowers Wilkins. Let's have a brief look at the main features
of Focal Theva No1 and B&W 606 S2 first before getting into our more
detailed comparison.
What size room are the Focal Theva No1 and B&W 606 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:
In the following sections, we will get into more detail in order to better understand how the Focal Theva No1 and B&W 606 S2 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Theva No1 features a 1" TNF Al/Mg inverted dome Tweeter and 1 x 6.5" Slatefiber Woofer with a Crossover frequency at 3000 Hz. On the other hand, the 606 S2 AE features a 1" Aluminum Decoupled Double Dome Tweeter and 1 x 6.5" Continuum Woofer .
Frequency Response
Theva No1 has a frequency range of 58-28kHz whereas 606 S2 AE has a frequency range of 52-28k Hz. With a minimum frequency of 52Hz, the 606 S2 AE can go significantly deeper on the low side and provide stronger bass compared to the Theva No1's min frequency of 58Hz.
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
Theva No1 and 606 S2 AE have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Theva No1 sensitivity is rated at 89 dB and the 606 S2 AE's is at 88 dB. This 1 dB difference makes the Focal Theva No1 a more sensitive speaker compared to B&W 606 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.
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 Theva No1 and 606 S2 AE features dual binding post speaker terminals for bi-amping or bi-wiring.
Focal Theva No1's Binding post terminals allows Bi-amping or bi-wiring
B&W 606 S2's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Theva No1 and 606 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
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 Focal Theva No1's and B&W 606 S2's external dimensions. Focal Theva No1 has external dimensions of 391.0 x 213.0 x 261.0mm ( 153/8 x 83/8 x 101/4) whereas B&W 606 S2 has external dimensions of 347.0 x 191.0 x 326.0mm ( 13-5/8 x 7-1/2 x 12-13/16inch) .
B&W 606 S2 is 22mm narrower and 44mm shorter than Focal Theva No1 but it is also 65mm deeper.
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 Focal Theva No1 is approximately 555.9cm2 / 86.2inch2 and base area of the B&W 606 S2 is approximately 622.7cm2 / 96.5inch2. The Theva No1 requires 11% less surface area than the 606 S2 AE which gives it a small advantage 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 Focal Theva No1 weighs 6.82kg / 15lbs and the B&W 606 S2 weighs 6.90kg / 15.2lbs. This makes the 606 S2 AE 1% heavier than the Theva No1.
Here is a comparison of how Theva No1 and 606 S2 AE's weights compare with the average, max and min weights in Passive Bookshelf class.
