History
What size room are the Q Acoustics 5040 and Q Acoustics 5090 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.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
Both 5040 and 5090 are 2-way speakers.

5040 features a 1" Soft-dome Tweeter and 2 x 5" Continuous Curved Cone Woofer with a Crossover frequency at 2500 Hz. On the other hand, the 5090 features a 1" Soft-dome Tweeter and 2 x 4.5" Coated paper Woofer with a Crossover frequency at 2100 Hz.
Frequency Response
5040 has a frequency range of 39-30k Hz whereas 5090 has a frequency range of 57-30k Hz. With a minimum frequency of 39Hz, the 5040 can go significantly deeper on the low side and provide stronger bass compared to the 5090's min frequency of 57Hz.
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
5040 and 5090 have the same Impedance of 6 ohms but where they differ is the sensitivity levels. 5040 sensitivity is rated at 91.5 dB and the 5090's is at 90.5 dB. This 1 dB difference makes the Q Acoustics 5040 a more sensitive speaker compared to Q Acoustics 5090, 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.
5040 and 5090 have the same power range of 25-150 watts.
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
5040 features Binding post type posts and 5090 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both 5040 and 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
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 5040's and Q Acoustics 5090's external dimensions. Q Acoustics 5040 has external dimensions of 969.0 x 362.0 x 293.0mm (38-1/8inch x 14-1/4inch 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 803mm shorter and 48mm less deeper than Q Acoustics 5040 but it is also 69mm wider.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Near-identical footprints. Q Acoustics 5040 is 48mm deeper, so it stands that much further out from the wall. Q Acoustics 5040 is 803mm taller.
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 5040 is approximately 1060.7cm2 / 164.4inch2 and base area of the Q Acoustics 5090 is approximately 1056.0cm2 / 163.7inch2. The 5040 requires 0% more surface area than the 5090 which gives it a small disadvantage on placement in tight spaces.
