What size room are the Wharfedale EVO4.1 and Wharfedale Reva 1 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:

EVO4.1 features a 1.18x2.36" AMT (Ribbon) Tweeter and 1 x 5" Kevlar Woofer. On the other hand, the Reva 1 features a 1" woven textile Dome Tweeter and 1 x 4.5" Woven Glass Fiber Woofer.
Frequency Response
EVO4.1 has a frequency range of 64-22k Hz whereas Reva 1 has a frequency range of 52-20k Hz. With a minimum frequency of 52Hz, the Reva 1 can go significantly deeper on the low side and provide stronger bass compared to the EVO4.1's min frequency of 64Hz.
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
EVO4.1 and Reva 1 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. EVO4.1 sensitivity is rated at 87 dB and the Reva 1's is at 86 dB. This 1 dB difference makes the Wharfedale EVO4.1 a more sensitive speaker compared to Wharfedale Reva 1, 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.
EVO4.1 can handle a max power of 100 watts RMS, whereas Reva 1 has a max power handling value of 60 watts RMS, 40 watts less than the EVO4.1.
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 EVO4.1 and Reva 1 features dual binding post speaker terminals for bi-amping or bi-wiring.
Wharfedale EVO4.1's Binding post terminals allows Bi-amping or bi-wiring
Wharfedale Reva 1's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both EVO4.1 and Reva 1 have bottom firing ports.
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 EVO4.1's and Wharfedale Reva 1's external dimensions. Wharfedale EVO4.1 has external dimensions of 335.0 x 210.0 x 295.0mm (13.1 x 8.2 x 11.6inch) whereas Wharfedale Reva 1 has external dimensions of 318.0 x 174.0 x 285.0mm (12-1/2 x 6-13/16 x 11-3/16inch).
Wharfedale EVO4.1 is clearly the larger of the two speakers. Its body is 36mm wider, 17mm taller and 10mm deeper than Wharfedale Reva 1.
Below you can see the front view size comparison of Wharfedale EVO4.1 and Wharfedale Reva 1 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 EVO4.1 is approximately 619.5cm2 / 96.0inch2 and base area of the Wharfedale Reva 1 is approximately 495.9cm2 / 76.9inch2. The EVO4.1 requires 25% more surface area than the Reva 1 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 EVO4.1 weighs 7.80kg / 17.2lbs and the Wharfedale Reva 1 weighs 5.64kg / 12.4lbs. This makes the EVO4.1 38% heavier than the Reva 1.
Here is a comparison of how EVO4.1 and Reva 1's weights compare with the average, max and min weights in Passive Bookshelf class.

Both are Wharfedale, from different ranges - so the house sound is shared and the differences are mostly in scale, engineering and price.
| Area | Better | Why |
|---|
| Bass | B | Wharfedale Reva 1 digs deeper - 52Hz against 64Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (87dB vs 86dB) - both want much the same power. |
| Headroom | A | Wharfedale EVO4.1 takes more power (100W vs 60W) - more in hand in a big room. |
| Size | depends | Wharfedale Reva 1 is easier to place; Wharfedale EVO4.1 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Wharfedale EVO4.1: bi-amping; Wharfedale Reva 1: bi-amping. Wharfedale EVO4.1 sits in a wider range (7 models), so a matched surround system is easier later. |
| Price | evenly matched | Much the same money ($799 vs $799 a pair). |
A Wharfedale EVO4.1 B Wharfedale Reva 1
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?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 64Hz anyway, so judge these on the other rows instead. Match it to your room: we rate Wharfedale Reva 1 the better fit for near-field listening; elsewhere the two are rated the same.
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.
