History
What size room are the Q Acoustics 3090c and Q Acoustics 3030c 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:

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 3090c and Q Acoustics 3030c compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

3090c features a 0.9" Soft-dome Tweeter and 2 x 4" Coated paper Woofer with a Crossover frequency at 2900 Hz. On the other hand, the 3030c features a 1" decoupled Tweeter and 1 x 5.5" Coated paper Woofer with a Crossover frequency at 2500Hz.
Frequency Response
3090c has a frequency range of 68-30k Hz whereas 3030c has a frequency range of 48-30k Hz. With a minimum frequency of 48Hz, the 3030c can go significantly deeper on the low side and provide stronger bass compared to the 3090c's min frequency of 68Hz.
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 Center Channel class in our database.

Center Channel Speakers
High Frequency
Center Channel 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
3090c and 3030c have the same Impedance of 6 ohms but where they differ is the sensitivity levels. 3090c sensitivity is rated at 92 dB and the 3030c's is at 86.5 dB. This 5 dB difference makes the Q Acoustics 3090c a more sensitive speaker compared to Q Acoustics 3030c, 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.
3090c can handle a max power of 120 watts RMS from the amp the whereas 3030c has a max power handling value of 90 watts RMS, 30 watts less than the 3090c.
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
3090c features Binding post type posts and 3030c has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both 3090c and 3030c 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 3090c's and Q Acoustics 3030c's external dimensions. Q Acoustics 3090c has external dimensions of 159 x 430 x 216 mm ( 6.3 x 16.9 x 8.5 in) whereas Q Acoustics 3030c has external dimensions of 325 x 205 x 329mm ( 12.8 x 8.1 x 13inch) .
Q Acoustics 3090c is 166mm shorter and 113mm less deeper than Q Acoustics 3030c but it is also 225mm 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 3090c is approximately 928.8cm2 / 144.0inch2 and base area of the Q Acoustics 3030c is approximately 674.5cm2 / 104.5inch2. The 3090c requires 38% more surface area than the 3030c which gives it a small disadvantage on placement in tight spaces.
