In this review, we will be comparing UBR62 and BW 606, two Passive Bookshelf speakers from ELAC and Bowers Wilkins. Let's have a brief look at the main features
of ELAC Uni-Fi Ref UBR62 and B&W 606 first before getting into our more
detailed comparison.
What size room are the ELAC Uni-Fi Ref UBR62 and B&W 606 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 ELAC Uni-Fi Ref UBR62 and B&W 606 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 UBR62 is a 3-way design whereas the BW 606 is a 2-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.

UBR62 features a 1" soft dome Tweeter , a 4" Midrange and 1 x 6.5" Aluminum Woofer . On the other hand, the BW 606 features a 1" Decoupled Carbon Hard-Dome Tweeter and 1 x 6.5" Continuum Woofer .
Frequency Response
UBR62 has a frequency range of 41-35k Hz whereas BW 606 has a frequency range of 52-28k Hz. With a minimum frequency of 41Hz, the UBR62 can go significantly deeper on the low side and provide stronger bass compared to the BW 606's min frequency of 52Hz.
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
UBR62 is a 6 ohms speaker compared to the BW 606 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. UBR62 sensitivity is rated at 85 dB and the BW 606's is rated at 88 dB. This 3 dB difference makes the B&W 606 a more sensitive speaker compared to ELAC Uni-Fi Ref UBR62, 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.
UBR62 can handle a max power of 140 watts RMS from the amp the whereas BW 606 has a max power handling value of 120 watts RMS, 20 watts less than the UBR62.
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 UBR62 and BW 606 features dual binding post speaker terminals for bi-amping or bi-wiring.
ELAC Uni-Fi Ref UBR62's Binding post terminals allows Bi-amping or bi-wiring
B&W 606's Post terminals allows Bi-amping or bi-wiring
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 ELAC Uni-Fi Ref UBR62's and B&W 606's external dimensions. ELAC Uni-Fi Ref UBR62 has external dimensions of 359.0 x 210.0 x 332.0mm ( 14-1/8 x 8-1/4 x 13-1/16inch) whereas B&W 606 has external dimensions of 345.0 x 190.0 x 324.0mm ( 13.5 x 7.4 x 12.7inch) .
ELAC Uni-Fi Ref UBR62 is clearly the larger of the two speakers. Its body is 20mm wider, 14mm taller and 8mm deeper than B&W 606.
Below you can see the front view size comparison of ELAC Uni-Fi Ref UBR62 and B&W 606 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 ELAC Uni-Fi Ref UBR62 is approximately 697.2cm2 / 108.1inch2 and base area of the B&W 606 is approximately 615.6cm2 / 95.4inch2. The UBR62 requires 13% more surface area than the BW 606 which gives it a small disadvantage 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 ELAC Uni-Fi Ref UBR62 weighs 10.70kg / 23.5lbs and the B&W 606 weighs 6.90kg / 15.2lbs. This makes the UBR62 55% heavier than the BW 606.
Here is a comparison of how UBR62 and BW 606's weights compare with the average, max and min weights in Passive Bookshelf class.
