What size room are the Wharfedale Reva 2 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:

The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers

Reva 2 features a 1" woven textile Dome Tweeter and 1 x 5" Woven Glass Fiber 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
Reva 2 has a frequency range of 48-20k Hz whereas BW 606 has a frequency range of 52-28k Hz. With a minimum frequency of 48Hz, the Reva 2 can go slightly deeper then the BW 606's min frequency of 52Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Reva 2 and BW 606 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Reva 2 sensitivity is rated at 86 dB and the BW 606's is at 88 dB. This 2 dB difference makes the B&W 606 a more sensitive speaker compared to Wharfedale Reva 2, hence will play louder with the same amount of watts.
Sensitivity
Bookshelf Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
BW 606 can handle a max power of 120 watts RMS, whereas Reva 2 has a max power handling value of 80 watts RMS, 40 watts less than the BW 606.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Both Reva 2 and BW 606 features dual binding post speaker terminals for bi-amping or bi-wiring.
Wharfedale Reva 2's Post terminals allows Bi-amping or bi-wiring
B&W 606's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Reva 2 has a bottom firing port whereas BW 606 has a rear firing ports. Wharfedale Reva 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
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Wharfedale Reva 2's and B&W 606's external dimensions. Wharfedale Reva 2 has external dimensions of 358.0 x 201.0 x 326.0mm (14-1/16 x 7-7/8 x 12-13/16inch) whereas B&W 606 has external dimensions of 345.0 x 190.0 x 324.0mm (13.5 x 7.4 x 12.7inch).
Wharfedale Reva 2 is clearly the larger of the two speakers. Its body is 11mm wider, 13mm taller and 2mm deeper than B&W 606.
Below you can see the front view size comparison of Wharfedale Reva 2 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 Wharfedale Reva 2 is approximately 655.3cm2 / 101.6inch2 and base area of the B&W 606 is approximately 615.6cm2 / 95.4inch2. The Reva 2 requires 6% more surface area than the BW 606 which gives it a small disadvantage on placement in tight spaces.
Here is 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 Wharfedale Reva 2 weighs 7.82kg / 17.2lbs and the B&W 606 weighs 6.90kg / 15.2lbs. This makes the Reva 2 13% heavier than the BW 606.

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.
| Area | Better | Why |
|---|
| Bass | A | Wharfedale Reva 2 digs deeper - 48Hz against 52Hz. A subwoofer would even that out. |
| Amplifier needs | B | B&W 606 is more sensitive (88dB vs 86dB), so it goes louder on the same amplifier. |
| Headroom | B | B&W 606 takes more power (120W vs 80W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | Wharfedale Reva 2: bi-amping; B&W 606: bi-amping. |
| Price | B | B&W 606 is cheaper - $899 against $999, about 10% less. |
A Wharfedale Reva 2 B B&W 606
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
B&W 606 has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. Match it to your room: we rate Wharfedale Reva 2 the better fit for near-field listening and a small room, and B&W 606 for a mid-size room and a large room. If your amplifier is modest, vintage or valve-based, B&W 606 is the safer partner - the other will want more current or more watts to sound its best.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
