606 S3 features a 1" Titanium Decoupled Double Dome Titanium Tweeter and 1 x 6.5" Continuum Woofer . On the other hand, the Lumina II features a 1.15" high definition DAD Tweeter and 1 x 6" paper cone Woofer with a Crossover frequency at 1800Hz.
Frequency Response
606 S3 has a frequency range of 52-28k Hz whereas Lumina II has a frequency range of 55-24k Hz. With a minimum frequency of 52Hz, the 606 S3 can go slightly deeper then the Lumina II's min frequency of 55Hz.
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.

High Frequency
Bookshelf Speakers
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 S3 is a 8 ohms speaker compared to the Lumina II 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 Lumina II can provide this impedance level.
These two speakers also have different sensitivity levels. 606 S3 sensitivity is rated at 88 dB and the Lumina II's is rated at 86 dB. This 2 dB difference makes the B&W 606 S3 a more sensitive speaker compared to Sonus Lumina II, 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.
606 S3 can handle a max power of 150 watts RMS from the amp the whereas 606 S3 has a max power handling value of 120 watts RMS , 30 watts less than the Lumina II.
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 606 S3 and Lumina II features dual binding post speaker terminals for bi-amping or bi-wiring.
B&W 606 S3's Binding post terminals allows Bi-amping or bi-wiring
Sonus Lumina II's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
606 S3 has a rear firing port whereas Lumina II has a front firing ports. Sonus Lumina II's front-firing port gives more flexibility in placement in regards to proximity to walls compared to B&W 606 S3 with its rear-firing port.
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 606 S3's and Sonus Lumina II's external dimensions. B&W 606 S3 has external dimensions of 344.0 x 189.0 x 328.0mm ( 13.6 x 7.4 x 12.9inch) whereas Sonus Lumina II has external dimensions of 304.0 x 180.0 x 263.0mm ( 12 x 7.1 x 10.3inch) .
B&W 606 S3 is clearly the larger of the two speakers. Its body is 9mm wider, 40mm taller and 65mm deeper than Sonus Lumina II.
Below you can see the front view size comparison of B&W 606 S3 and Sonus Lumina II 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 606 S3 is approximately 619.9cm2 / 96.1inch2 and base area of the Sonus Lumina II is approximately 473.4cm2 / 73.4inch2. The 606 S3 requires 31% more surface area than the Lumina II which gives it a small disadvantage on placement in tight spaces.
