In this review, we will be comparing 3030i and 3020i, two Passive Bookshelf speakers by Q Acoustics Let's have a brief look at the main features
of Q Acoustics 3030i and Q Acoustics 3020i first before getting into our more
detailed comparison.
3030i and 3020i are members of Q Acoustics's 3000 series of speakers. Below you can find the loudspeakers from this series.

What size room are the Q Acoustics 3030i and Q Acoustics 3020i 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 3030i and Q Acoustics 3020i compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

3030i features a 1" decoupled Tweeter and 1 x 6.5" Coated paper Woofer with a Crossover frequency at 2400Hz. On the other hand, the 3020i features a 0.9" decoupled Tweeter and 1 x 5" Coated paper Woofer with a Crossover frequency at 2400Hz and 2400Hz.
Frequency Response
3030i has a frequency range of 46-30k Hz whereas 3020i has a frequency range of 64-30k Hz.
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.

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
3030i and 3020i have the same Impedance of 6 ohms and their sensitivity is also same at 88 dB.

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.
3030i and 3020i has the same power range of 25-75 watts.
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
3030i features Post type posts and 3020i has a Post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both 3030i and 3020i have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 3030i's and Q Acoustics 3020i's external dimensions. Q Acoustics 3030i has external dimensions of 325.0 x 200.0 x 329.0mm ( 12.7 x 7.8 x 12.9inch) whereas Q Acoustics 3020i has external dimensions of 278.0 x 170.0 x 282.0mm ( 10.9 x 6.6 x 11.1inch) .
Q Acoustics 3030i is clearly the larger of the two speakers. Its body is 30mm wider, 47mm taller and 47mm deeper than Q Acoustics 3020i.
Below you can see the front view size comparison of Q Acoustics 3030i and Q Acoustics 3020i 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 3030i is approximately 658.0cm2 / 102.0inch2 and base area of the Q Acoustics 3020i is approximately 479.4cm2 / 74.3inch2. The 3030i requires 37% more surface area than the 3020i 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 3030i weighs 6.20kg / 13.6lbs and the Q Acoustics 3020i weighs 4.80kg / 10.6lbs. This makes the 3030i 29% heavier than the 3020i.
Here is a comparison of how 3030i and 3020i's weights compare with the average, max and min weights in Passive Bookshelf class.
