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 Diamond 220 features a 1" Dome Tweeter and 1 x 5" Woven Kevlar Woofer with a Crossover frequency at 2200Hz.
Frequency Response
3020i has a frequency range of 64-30k Hz whereas Diamond 220 has a frequency range of 56-20k Hz. With a minimum frequency of 56Hz, the Diamond 220 can go significantly deeper on the low side and provide stronger bass compared to the 3020i'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
3020i is a 6 ohms speaker compared to the Diamond 220 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 Diamond 220's is rated at 86 dB. This 2 dB difference makes the Q Acoustics 3020i a more sensitive speaker compared to Wharfedale 220, 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.
Diamond 220 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 Diamond 220.
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
Diamond 220 features Post posts which make bi-amping or bi-wiring possible. 3020i has a Binding post which doesn't feature bi-amping/bi-wiring.
Wharfedale 220's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
3020i has a rear firing port whereas Diamond 220 has a bottom firing ports. Wharfedale 220'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 220'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 220 has external dimensions of 315.0 x 174.0 x 255.0mm (12.4 x 6.8 x 10.0inch).
Q Acoustics 3020i is 4mm narrower and 37mm shorter than Wharfedale 220 but it is also 27mm deeper.
Below you can see the front view size comparison of Q Acoustics 3020i and Wharfedale 220 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 220 is approximately 443.7cm2 / 68.8inch2. The 3020i requires 8% more surface area than the Diamond 220 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 Q Acoustics 3020i weighs 4.80kg / 10.6lbs and the Wharfedale 220 weighs 5.32kg / 11.7lbs. This makes the Diamond 220 11% heavier than the 3020i.

These sit in different price classes - Q Acoustics 3020i costs roughly 1.6x what Wharfedale 220 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 | Wharfedale 220 digs deeper - 56Hz against 64Hz. A subwoofer would even that out. |
| Amplifier needs | A | Q Acoustics 3020i is more sensitive (88dB vs 86dB), so it goes louder on the same amplifier. |
| Amplifier match | B | Wharfedale 220 is the easier load at 8 ohms. |
| Headroom | B | Wharfedale 220 takes more power (100W vs 75W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | Wharfedale 220: bi-amping. Q Acoustics 3020i sits in a wider range (6 models), so a matched surround system is easier later. |
| Price | B | Wharfedale 220 is cheaper - $249 against $399, about 38% less; arguably a different class. |
A Q Acoustics 3020i B Wharfedale 220
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?
Wharfedale 220 is the easier recommendation: it leads on most of the measured areas and costs less. Take Q Acoustics 3020i if its size, looks or fit in your room suit you better. 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 Q Acoustics 3020i 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.
