What size room are the Q Acoustics 3030c and Q Acoustics 5020 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:

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.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.

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 5020 features a 1" Soft-dome Tweeter and 1 x 5" Continuous Curved Cone Woofer with a Crossover frequency at 2500 Hz.
Frequency Response
3030c has a frequency range of 48-30k Hz whereas 5020 has a frequency range of 53-30k Hz. With a minimum frequency of 48Hz, the 3030c can go significantly deeper on the low side and provide stronger bass compared to the 5020's min frequency of 53Hz.
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
3030c and 5020 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 5020's is at 87.9 dB. This 1 dB difference makes the Q Acoustics 5020 a more sensitive speaker compared to Q Acoustics 3030c, 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.
5020 can handle a max power of 100 watts RMS, whereas 3030c has a max power handling value of 90 watts RMS, 10 watts less than the 5020.
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
3030c features Binding post type posts and 5020 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both 3030c and 5020 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 3030c's and Q Acoustics 5020'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 5020 has external dimensions of 286.0 x 181.0 x 293.0mm (11-1/4nch x 7-1/8inch x 11-1/2inch).
Q Acoustics 3030c is clearly the larger of the two speakers. Its body is 24mm wider, 39mm taller and 36mm deeper than Q Acoustics 5020.
Below you can see the front view size comparison of Q Acoustics 3030c and Q Acoustics 5020 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 5020 is approximately 530.3cm2 / 82.2inch2. The 3030c requires 27% more surface area than the 5020 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 3030c weighs 7.50kg / 16.5lbs and the Q Acoustics 5020 weighs 7.00kg / 15.4lbs. This makes the 3030c 7% heavier than the 5020.
Here is a comparison of how 3030c and 5020's weights compare with the average, max and min weights in Passive Bookshelf class.

Both are Q Acoustics, from different ranges - so the house sound is shared and the differences are mostly in scale, engineering and price.
| Area | Better | Why |
|---|
| Bass | A | Q Acoustics 3030c digs deeper - 48Hz against 53Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (87dB vs 88dB) - both want much the same power. |
| Headroom | evenly matched | Similar power handling (90W vs 100W). |
| Size | depends | Q Acoustics 5020 is easier to place; Q Acoustics 3030c is bigger, which usually goes with fuller bass. Your room decides. |
| Price | A | Q Acoustics 3030c is cheaper - $699 against $899, about 22% less. |
A Q Acoustics 3030c B Q Acoustics 5020
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?
Q Acoustics 3030c has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 53Hz anyway, so judge these on the other rows instead. In a large or open-plan room, Q Acoustics 3030c has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Q Acoustics 5020 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.
