History
What size room are the Q Acoustics 3030c and Q Acoustics 3020c 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:

(* Approximate Room sizes: Small < 100sq. ft / 9 m2,
Mid-size: 100-220 sq. ft / 9-20 m2, Large 220-400 sq. ft / 20-36 m2, Very Large: >
400 sq. ft / 36 m2.
Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the Q Acoustics 3030c and Q Acoustics 3020c compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

3030c features a 1" decoupled Tweeter and 1 x 5.5" Coated paper Woofer with a Crossover frequency at 2500Hz. On the other hand, the 3020c features a 0.9" decoupled Tweeter and 1 x 4.74" Coated paper Woofer with a Crossover frequency at 2600Hz.
Frequency Response
3030c has a frequency range of 48-30k Hz whereas 3020c has a frequency range of 60-30k Hz. With a minimum frequency of 48Hz, the 3030c can go significantly deeper on the low side and provide stronger bass compared to the 3020c's min frequency of 60Hz.
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
Bookshelf Speakers
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
3030c and 3020c have the same Impedance of 6 ohms but where they differ is the sensitivity levels. 3030c sensitivity is rated at 86.5 dB and the 3020c's is at 87 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.
3030c and 3020c has the same power range of 25-90 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
3030c features Binding post type posts and 3020c has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both 3030c and 3020c 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 3030c's and Q Acoustics 3020c's external dimensions. Q Acoustics 3030c has external dimensions of 325 x 205 x 329mm ( 12.8 x 8.1 x 13inch) whereas Q Acoustics 3020c has external dimensions of 279 x 175 x 281 mm ( 11.0 x 6.9 x 11.1 in) .
Q Acoustics 3030c is clearly the larger of the two speakers. Its body is 30mm wider, 46mm taller and 48mm deeper than Q Acoustics 3020c.
Below you can see the front view size comparison of Q Acoustics 3030c and Q Acoustics 3020c 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 3030c is approximately 674.5cm2 / 104.5inch2 and base area of the Q Acoustics 3020c is approximately 491.8cm2 / 76.2inch2. The 3030c requires 37% more surface area than the 3020c 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 3030c weighs 7.50kg / 16.5lbs and the Q Acoustics 3020c weighs 5.50kg / 12.1lbs. This makes the 3030c 36% heavier than the 3020c.
Here is a comparison of how 3030c and 3020c's weights compare with the average, max and min weights in Passive Bookshelf class.
