In this review, we will be comparing 3020i and Diamond 220, two Passive Bookshelf speakers from Q Acoustics and Wharfedale. Let's have a brief look at the main features
of Q Acoustics 3020i and Wharfedale 220 first before getting into our more
detailed comparison.
What size room are the Q Acoustics 3020i and Wharfedale 220 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:
In the following sections, we will get into more detail in order to better understand how the Q Acoustics 3020i and Wharfedale 220 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

3020i features a 0.9" decoupled Tweeter and 1 x 5" Coated paper Woofer with a Crossover frequency at 2400Hz and 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 46Hz, the 3020i can go significantly deeper on the low side and provide stronger bass compared to the Diamond 220's min frequency of 56Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Bookshelf class in our database.

High Frequency

None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. 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.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
3020i can handle a max power of 100 watts RMS from the amp the whereas 3020i has a max power handling value of 75 watts RMS , 25 watts less than the Diamond 220.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Diamond 220 features Post posts which make bi-amping or bi-wiring possible. 3020i has a 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
Size of a speaker can sometimes become 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 an 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.
Here is a comparison of how 3020i and Diamond 220's weights compare with the average, max and min weights in Passive Bookshelf class.
