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

606 S2 AE is a 8 ohms speaker compared to the Sib-T which has a nominal impedance of 4 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Sib-T can provide this impedance level.

These two speakers also have different sensitivity levels. 606 S2 AE sensitivity is rated at 88 dB and the Sib-T's is rated at 90 dB. This 2 dB difference makes the Focal Sib-T a more sensitive speaker compared to B&W 606 S2, hence will play louder with the same amount of watts.

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 606 S2 is approximately 622.7cm2 / 96.5inch2 and base area of the Focal Sib-T is approximately 243.1cm2 / 37.7inch2. The 606 S2 AE requires 156% more surface area than the Sib-T which gives it a small disadvantage 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.
