3020i features a 0.9" decoupled Tweeter and 1 x 5" Coated paper Woofer with a Crossover frequency at 2400Hz. On the other hand, the EVO4.1 features a 1.18x2.36" AMT (Ribbon) Tweeter and 1 x 5" Kevlar Woofer.
Frequency Response
3020i has a frequency range of 64-30k Hz whereas EVO4.1 has a frequency range of 64-22k Hz.
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
3020i is a 6 ohms speaker compared to the EVO4.1 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. 3020i sensitivity is rated at 88 dB and the EVO4.1's is rated at 87 dB. This 1 dB difference makes the Q Acoustics 3020i a more sensitive speaker compared to Wharfedale EVO4.1, hence will play louder with the same amount of watts.
Sensitivity

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 3020i has a max power handling value of 75 watts RMS, 25 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
EVO4.1 features Binding post posts which make bi-amping or bi-wiring possible. 3020i has a Binding post which doesn't feature bi-amping/bi-wiring.
Wharfedale EVO4.1's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
3020i has a rear firing port whereas EVO4.1 has a bottom firing ports. Wharfedale EVO4.1's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Q Acoustics 3020i 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 Q Acoustics 3020i's and Wharfedale EVO4.1's external dimensions. Q Acoustics 3020i has external dimensions of 278.0 x 170.0 x 282.0mm (10.9 x 6.6 x 11.1inch) whereas Wharfedale EVO4.1 has external dimensions of 335.0 x 210.0 x 295.0mm (13.1 x 8.2 x 11.6inch).
Wharfedale EVO4.1 is clearly the larger of the two speakers. Its body is 40mm wider, 57mm taller and 13mm deeper than Q Acoustics 3020i.
Below you can see the front view size comparison of Q Acoustics 3020i and Wharfedale EVO4.1 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 Q Acoustics 3020i is approximately 479.4cm2 / 74.3inch2 and base area of the Wharfedale EVO4.1 is approximately 619.5cm2 / 96.0inch2. The 3020i requires 23% less surface area than the EVO4.1 which gives it a small advantage 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 Q Acoustics 3020i weighs 4.80kg / 10.6lbs and the Wharfedale EVO4.1 weighs 7.80kg / 17.2lbs. This makes the EVO4.1 63% heavier than the 3020i.

These sit in different price classes - Wharfedale EVO4.1 costs roughly 2x what Q Acoustics 3020i 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 | evenly matched | Much the same reach (64Hz vs 64Hz). |
| Amplifier needs | evenly matched | Similar sensitivity (88dB vs 87dB) - both want much the same power. |
| Amplifier match | B | Wharfedale EVO4.1 is the easier load at 8 ohms. |
| Headroom | B | Wharfedale EVO4.1 takes more power (100W vs 75W) - more in hand in a big room. |
| Size | depends | Q Acoustics 3020i is easier to place; Wharfedale EVO4.1 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | B | Wharfedale EVO4.1: bi-amping. |
| Price | A | Q Acoustics 3020i is cheaper - $399 against $799, about 50% less; arguably a different class. |
A Q Acoustics 3020i B Wharfedale EVO4.1
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?
The usual trade-off: Wharfedale EVO4.1 measures better, Q Acoustics 3020i costs about about 100% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. Match it to your room: we rate Q Acoustics 3020i the better fit for near-field listening; elsewhere the two are rated the same. In a large or open-plan room, Wharfedale EVO4.1 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Q Acoustics 3020i is the easier speaker to get right.
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.
