What size room are the Wharfedale EVO4.1 and B&W 705 S2 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 705 S2 features a 1" Solid Body Soft-Dome Tweeter and 1 x 6.5" Continuum Woofer.
Frequency Response
EVO4.1 has a frequency range of 64-22k Hz whereas 705 S2 has a frequency range of 50-28k Hz. With a minimum frequency of 50Hz, the 705 S2 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 705 S2 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 705 S2's is at 88 dB. This 1 dB difference makes the B&W 705 S2 a more sensitive speaker compared to Wharfedale EVO4.1, 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.
705 S2 can handle a max power of 120 watts RMS, whereas EVO4.1 has a max power handling value of 100 watts RMS, 20 watts less than the 705 S2.
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 705 S2 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
Cabinet Type and Port Position
EVO4.1 has a bottom firing port whereas 705 S2 has a rear firing ports. Wharfedale EVO4.1's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to B&W 705 S2 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 EVO4.1's and B&W 705 S2'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 B&W 705 S2 has external dimensions of 407.0 x 200.0 x 301.0mm (16-inch x 7.8-inch x 11.9-inch).
Wharfedale EVO4.1 is 72mm shorter and 6mm less deeper than B&W 705 S2 but it is also 10mm wider.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Near-identical footprints. B&W 705 S2 is 72mm taller.
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 B&W 705 S2 is approximately 602.0cm2 / 93.3inch2. The EVO4.1 requires 3% more surface area than the 705 S2 which gives it a small disadvantage on placement in tight spaces.
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 B&W 705 S2 weighs 9.32kg / 20.5lbs. This makes the 705 S2 19% heavier than the EVO4.1.

These sit in different price classes - B&W 705 S2 costs roughly 4.1x what Wharfedale EVO4.1 does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | B | B&W 705 S2 digs deeper - 50Hz against 64Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (87dB vs 88dB) - both want much the same power. |
| Headroom | evenly matched | Similar power handling (100W vs 120W). |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | Wharfedale EVO4.1: bi-amping; B&W 705 S2: bi-amping. |
| Price | A | Wharfedale EVO4.1 is cheaper - $799 against $3,299, about 76% less; arguably a different class. |
A Wharfedale EVO4.1 B B&W 705 S2
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 705 S2 is ahead, but only on 1 of the measured areas, and it costs about 4.1x the price. That is a lot of money for a narrow margin on paper - Wharfedale EVO4.1 looks like the sensible buy unless something else about the B&W 705 S2 appeals to you. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 64Hz anyway, which makes the cheaper Wharfedale EVO4.1 much easier to justify. Match it to your room: we rate Wharfedale EVO4.1 the better fit for near-field listening and a small room, and B&W 705 S2 for a mid-size room and a large room.
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.
