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 Q Acoustics 5090 features a 1" Soft-dome Tweeter and 2 x 4.5" Continuous Curved Cone Woofer with a Crossover frequency at 2100 Hz.
Frequency Response
Q Acoustics 5020 has a frequency range of 53-30k Hz whereas Q Acoustics 5090 has a frequency range of 57-30k Hz. With a minimum frequency of 53Hz, the Q Acoustics 5020 can go slightly deeper then the Q Acoustics 5090's min frequency of 57Hz.
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
Q Acoustics 5020 and Q Acoustics 5090 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 Q Acoustics 5090's is at 90.5 dB. This 3 dB difference makes the Q Acoustics 5090 a more sensitive speaker compared to Q Acoustics 5020, hence will play louder with the same amount of watts.

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 150 watts RMS from the amp the whereas Q Acoustics 5020 has a max power handling value of 100 watts RMS , 50 watts less than the Q Acoustics 5090.
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 Binding post type posts and Q Acoustics 5090 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Q Acoustics 5020 and Q Acoustics 5090 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 5090'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 5090 has external dimensions of 166.0 x 431.0 x 245.0mm ( 6-1/2inch x 16-15/16inch x 9-5/8inch ) .
Q Acoustics 5090 is 120mm shorter and 48mm less deeper than Q Acoustics 5020 but it is also 250mm wider.
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 5090 is approximately 1056.0cm2 / 163.7inch2. The Q Acoustics 5020 requires 50% less surface area than the Q Acoustics 5090 which gives it a small advantage on placement in tight spaces.
