In this review, we will be comparing Q Acoustics 5020 and 3030i, two Passive Bookshelf speakers by Q Acoustics Let's have a brief look at the main features
of Q Acoustics 5020 and Q Acoustics 3030i first before getting into our more
detailed comparison.
What size room are the Q Acoustics 5020 and Q Acoustics 3030i 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 5020 and Q Acoustics 3030i compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Q Acoustics 5020 features a 1" Soft-dome Tweeter and 1 x 5" Continuous Curved Cone Woofer with a Crossover frequency at 2500 Hz. On the other hand, the 3030i features a 1" decoupled Tweeter and 1 x 6.5" Coated paper Woofer with a Crossover frequency at 2400Hz.
Frequency Response
Q Acoustics 5020 has a frequency range of 53-30k Hz whereas 3030i has a frequency range of 46-30k Hz. With a minimum frequency of 46Hz, the 3030i can go significantly deeper on the low side and provide stronger bass compared to the Q Acoustics 5020's min frequency of 53Hz.
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
Q Acoustics 5020 and 3030i have the same Impedance of 6 ohms but where they differ is the sensitivity levels. Q Acoustics 5020 sensitivity is rated at 87.9 dB and the 3030i's is at 88 dB.
Sensitivity

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.
Q Acoustics 5020 can handle a max power of 100 watts RMS from the amp the whereas 3030i has a max power handling value of 75 watts RMS, 25 watts less than the Q Acoustics 5020.
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
Q Acoustics 5020 features Post type posts and 3030i has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Q Acoustics 5020 and 3030i 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 5020's and Q Acoustics 3030i's external dimensions. 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 ) whereas Q Acoustics 3030i has external dimensions of 325.0 x 200.0 x 329.0mm ( 12.7 x 7.8 x 12.9inch) .
Q Acoustics 3030i is clearly the larger of the two speakers. Its body is 19mm wider, 39mm taller and 36mm deeper than Q Acoustics 5020.
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 5020 is approximately 530.3cm2 / 82.2inch2 and base area of the Q Acoustics 3030i is approximately 658.0cm2 / 102.0inch2. The Q Acoustics 5020 requires 19% less surface area than the 3030i which gives it a small advantage on placement in tight spaces.
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 5020 weighs 7.00kg / 15.4lbs and the Q Acoustics 3030i weighs 6.20kg / 13.6lbs. This makes the Q Acoustics 5020 13% heavier than the 3030i.
Here is a comparison of how Q Acoustics 5020 and 3030i's weights compare with the average, max and min weights in Passive Bookshelf class.
