What size room are the Q Acoustics 5050 and PSB Imagine X2T 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:

Drivers
One of the fundamental differences between these two speakers is that 5050 is a 2-way design whereas the Imagine X2T is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

5050 features a 1" Soft-dome Tweeter and 2 x 6" Continuous Curved Cone Woofer with a Crossover frequency at 2700 Hz. On the other hand, the Imagine X2T features a 1" titanium with neodymium magnets Dome Tweeter, a 5.25" Midrange and 2 x 6.2" Clay/Ceramic/Poly Woofer with a Crossover frequency at 500Hz and 2200Hz.
Frequency Response
5050 has a frequency range of 39-30k Hz whereas Imagine X2T has a frequency range of 30-23k Hz. With a minimum frequency of 30Hz, the Imagine X2T can go significantly deeper on the low side and provide stronger bass compared to the 5050's min frequency of 39Hz.
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
5050 is a 6 ohms speaker compared to the Imagine X2T which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. 5050 sensitivity is rated at 91.5 dB and the Imagine X2T's is rated at 90 dB. This 2 dB difference makes the Q Acoustics 5050 a more sensitive speaker compared to PSB Imagine X2T, 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.
Imagine X2T can handle a max power of 200 watts RMS, whereas 5050 has a max power handling value of 175 watts RMS, 25 watts less than the Imagine X2T.
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
Imagine X2T features 5-Way post posts which make bi-amping or bi-wiring possible. 5050 has a Binding post which doesn't feature bi-amping/bi-wiring.

PSB Imagine X2T's 5-Way post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
5050 has a rear firing port whereas Imagine X2T has a front firing ports. PSB Imagine X2T's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Q Acoustics 5050 with its rear-firing port.
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 5050's and PSB Imagine X2T's external dimensions. Q Acoustics 5050 has external dimensions of 1100.0 x 320.0 x 439.0mm (40.0 x 15.2 x 13.2 in) whereas PSB Imagine X2T has external dimensions of 1020.0 x 229.0 x 426.0mm (40-1/8 x 9 x 16-3/4inch).
Q Acoustics 5050 is clearly the larger of the two speakers. Its body is 91mm wider, 80mm taller and 13mm deeper than PSB Imagine X2T.
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 5050 is approximately 1404.8cm2 / 217.7inch2 and base area of the PSB Imagine X2T is approximately 975.5cm2 / 151.2inch2. The 5050 requires 44% more surface area than the Imagine X2T which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Q Acoustics 5050 weighs 21.60kg / 47.5lbs and the PSB Imagine X2T weighs 23.60kg / 51.9lbs. This makes the Imagine X2T 9% heavier than the 5050.
Here is a comparison of how 5050 and Imagine X2T's weights compare with the average, max and min weights in Passive Floor-standing class.

A generation apart: Q Acoustics 5050 is the newer design, against a 2013 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | B | PSB Imagine X2T digs deeper - 30Hz against 39Hz. A subwoofer would even that out. |
| Amplifier needs | A | Q Acoustics 5050 is more sensitive (92dB vs 90dB), so it goes louder on the same amplifier. |
| Amplifier match | B | PSB Imagine X2T is the easier load at 8 ohms. |
| Headroom | evenly matched | Similar power handling (175W vs 200W). |
| Size | depends | PSB Imagine X2T is easier to place; Q Acoustics 5050 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | B | PSB Imagine X2T: bi-amping. |
| Price | B | PSB Imagine X2T is cheaper - $1,500 against $1,999, about 25% less. |
A Q Acoustics 5050 B PSB Imagine X2T
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
PSB Imagine X2T is the easier recommendation: it leads on most of the measured areas and costs less. Take Q Acoustics 5050 if its size, looks or fit in your room suit you better. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 39Hz anyway, so judge these on the other rows instead. In a large or open-plan room, Q Acoustics 5050 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, PSB Imagine X2T is the easier speaker to get right.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
