History
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:

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.
Frequency Response
3030i has a frequency range of 46-30k Hz whereas 3020i has a frequency range of 64-30k Hz. With a minimum frequency of 46Hz, the 3030i 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
3030i and 3020i have the same Impedance of 6 ohms and their sensitivity is also same at 88 dB.
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.
3030i and 3020i have the same power range of 25-75 watts.
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
3030i features Binding post type posts and 3020i has a Binding 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
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 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 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.

Siblings in Q Acoustics's 3000i series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | A | Q Acoustics 3030i digs deeper - 46Hz against 64Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (88dB vs 88dB) - both want much the same power. |
| Headroom | evenly matched | Similar power handling (75W vs 75W). |
| Size | depends | Q Acoustics 3020i is easier to place; Q Acoustics 3030i is bigger, which usually goes with fuller bass. Your room decides. |
| Price | B | Q Acoustics 3020i is cheaper - $399 against $499, about 20% less. |
A Q Acoustics 3030i B Q Acoustics 3020i
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: Q Acoustics 3030i measures better, Q Acoustics 3020i costs about about 25% 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. 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 Q Acoustics 3020i much easier to justify. In a large or open-plan room, Q Acoustics 3030i 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.
