What size room are the B&W 606 and Wharfedale EVO4.2 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.)
In the following sections, we will get into more detail in order to better understand how the B&W 606 and Wharfedale EVO4.2 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that BW 606 is a 2-way design whereas the EVO4.2 is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

BW 606 features a 1" Decoupled Carbon Hard-Dome Tweeter and 1 x 6.5" Continuum Woofer . On the other hand, the EVO4.2 features a 1.18x2.36" AMT (Ribbon) Tweeter , a 2" Midrange and 1 x 6.5" Kevlar Woofer .
Frequency Response
BW 606 has a frequency range of 52-28k Hz whereas EVO4.2 has a frequency range of 54-22k Hz. With a minimum frequency of 52Hz, the BW 606 can go slightly deeper then the EVO4.2's min frequency of 54Hz.
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
BW 606 and EVO4.2 have the same Impedance of 8 ohms and their sensitivity is also same at 88 dB.

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 BW 606 and EVO4.2 features dual binding post speaker terminals for bi-amping or bi-wiring.
B&W 606's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
BW 606 has a rear firing port whereas EVO4.2 has a bottom firing ports. Wharfedale EVO4.2's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to B&W 606 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's and Wharfedale EVO4.2's external dimensions. B&W 606 has external dimensions of 345.0 x 190.0 x 324.0mm ( 13.5 x 7.4 x 12.7inch) whereas Wharfedale EVO4.2 has external dimensions of 455.0 x 250.0 x 350.0mm ( 17.9 x 9.8 x 13.7inch) .
Wharfedale EVO4.2 is clearly the larger of the two speakers. Its body is 60mm wider, 110mm taller and 26mm deeper than B&W 606.
Below you can see the front view size comparison of B&W 606 and Wharfedale EVO4.2 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 is approximately 615.6cm2 / 95.4inch2 and base area of the Wharfedale EVO4.2 is approximately 875.0cm2 / 135.6inch2. The BW 606 requires 30% less surface area than the EVO4.2 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 606 weighs 6.90kg / 15.2lbs and the Wharfedale EVO4.2 weighs 13.40kg / 29.5lbs. This makes the EVO4.2 94% heavier than the BW 606.
Here is a comparison of how BW 606 and EVO4.2's weights compare with the average, max and min weights in Passive Bookshelf class.
