What size room are the Q Acoustics 3050c and Q Acoustics 3090c 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:

Listening Environment* Q Acoustics 3050c Q Acoustics 3090c
Near-field Bad Average
Small Room Poor Good
Mid-size Room Good Average
Large Room Good Poor
Very Large Room Poor Bad

(* Approximate Room sizes: Small < 100sq. ft / 9 m2, Mid-size: 100-220 sq. ft / 9-20 m2, Large 220-400 sq. ft / 20-36 m2, Very Large: > 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 3050c and Q Acoustics 3090c compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Woofer 2 x 5.5-inch 2 x 4-inch

3050c features a 0.9" decoupled Tweeter and 2 x 5.5" Coated paper Woofer with a Crossover frequency at 2400 Hz. On the other hand, the 3090c features a 0.9" Soft-dome Tweeter and 2 x 4" Coated paper Woofer with a Crossover frequency at 2900 Hz.

Frequency Response

3050c has a frequency range of 42-30k Hz whereas 3090c has a frequency range of 68-30k Hz. With a minimum frequency of 42Hz, the 3050c 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 Floor-standing 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

3050c and 3090c have the same Impedance of 6 ohms but where they differ is the sensitivity levels. 3050c sensitivity is rated at 90 dB and the 3090c's is at 92 dB. This 2 dB difference makes the Q Acoustics 3090c a more sensitive speaker compared to Q Acoustics 3050c, 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.

3050c can handle a max power of 150 watts RMS from the amp the whereas 3090c has a max power handling value of 120 watts RMS, 30 watts less than the 3050c.

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

3050c features Binding post type posts and 3090c has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position

Both 3050c and 3090c 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 3050c's and Q Acoustics 3090c's external dimensions. Q Acoustics 3050c has external dimensions of 1020 x 315 x 316 mm ( 40.2 x 12.4 x 12.4 in) whereas Q Acoustics 3090c has external dimensions of 159 x 430 x 216 mm ( 6.3 x 16.9 x 8.5 in) .

Q Acoustics 3090c is 861mm shorter and 100mm less deeper than Q Acoustics 3050c but it is also 115mm 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 3050c is approximately 995.4cm2 / 154.3inch2 and base area of the Q Acoustics 3090c is approximately 928.8cm2 / 144.0inch2. The 3050c requires 7% more surface area than the 3090c which gives it a small disadvantage on placement in tight spaces.
