History
What size room are the Q Acoustics 3050i and Q Acoustics 3090Ci 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.)

3050i features a 0.9" decoupled Tweeter and 2 x 6.5" Coated paper Woofer with a Crossover frequency at 2500 Hz. On the other hand, the 3090Ci features a 1" Soft-dome Tweeter and 2 x 4" Coated paper Woofer with a Crossover frequency at 2700 Hz.
Frequency Response
3050i has a frequency range of 44-30k Hz whereas 3090Ci has a frequency range of 75-30k Hz. With a minimum frequency of 44Hz, the 3050i can go significantly deeper on the low side and provide stronger bass compared to the 3090Ci's min frequency of 75Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing 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
3050i and 3090Ci have the same Impedance of 6 ohms but where they differ is the sensitivity levels. 3050i sensitivity is rated at 91 dB and the 3090Ci's is at 89 dB. This 2 dB difference makes the Q Acoustics 3050i a more sensitive speaker compared to Q Acoustics 3090Ci, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing 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.
3050i can handle a max power of 175 watts RMS, whereas 3090Ci has a max power handling value of 100 watts RMS, 75 watts less than the 3050i.
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
3050i features Binding post type posts and 3090Ci has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both 3050i and 3090Ci 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 3050i's and Q Acoustics 3090Ci's external dimensions. Q Acoustics 3050i has external dimensions of 1020 x 310 x 320 mm (40.2 x 12.2 x 12.6 in) whereas Q Acoustics 3090Ci has external dimensions of 153 x 430 x 216 mm (6 x 16.9 x 8.5 in).
Q Acoustics 3090Ci is 867mm shorter and 104mm less deeper than Q Acoustics 3050i but it is also 120mm 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 3050i is approximately 992.0cm2 / 153.8inch2 and base area of the Q Acoustics 3090Ci is approximately 928.8cm2 / 144.0inch2. The 3050i requires 7% more surface area than the 3090Ci which gives it a small disadvantage on placement in tight spaces.
