What size room are the PSB Imagine X2T and KEF Q750 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 PSB Imagine X2T and KEF Q750 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Imagine X2T is a 3-way design whereas the Q750 is a 2-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.

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. On the other hand, the Q750 features a 1" vented aluminum Dome Tweeter and 2 x 6.5" Aluminum Woofer with a Crossover frequency at 2500Hz.
Frequency Response
Imagine X2T has a frequency range of 30-23k Hz whereas Q750 has a frequency range of 48-28k 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 Q750's min frequency of 48Hz.
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.

High Frequency

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
Imagine X2T and Q750 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Imagine X2T sensitivity is rated at 90 dB and the Q750's is at 88 dB. This 2 dB difference makes the PSB Imagine X2T a more sensitive speaker compared to KEF Q750, 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.
Imagine X2T can handle a max power of 200 watts RMS from the amp the whereas Q750 has a max power handling value of 150 watts RMS, 50 watts less than the Imagine X2T.
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
Imagine X2T features 5-Way post posts which make bi-amping or bi-wiring possible. Q750 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
Both Imagine X2T and Q750 have front firing ports. front ported speakers offers more flexibility in placement in regards to proximity to walls&surfaces compared to rear ported speakers.
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 PSB Imagine X2T's and KEF Q750's external dimensions. PSB Imagine X2T has external dimensions of 1020.0 x 229.0 x 426.0mm ( 40-1/8 x 9 x 16-3/4inch) whereas KEF Q750 has external dimensions of 945.0 x 328.0 x 315.0mm ( 37-3/16 x 12-7/8 x 12-3/8inch) .
KEF Q750 is 75mm shorter and 111mm less deeper than PSB Imagine X2T but it is also 99mm 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 PSB Imagine X2T is approximately 975.5cm2 / 151.2inch2 and base area of the KEF Q750 is approximately 1033.2cm2 / 160.1inch2. The Imagine X2T requires 6% less surface area than the Q750 which gives it a small advantage on placement in tight spaces.
