In this review, we will be comparing Dymension DM40 and Imagine X2T, two Passive Floor-standing speakers from Definitive Technology and PSB. Let's have a brief look at the main features
of Definitive Dymension DM40 and PSB Imagine X2T first before getting into our more
detailed comparison.
What size room are the Definitive Dymension DM40 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:
In the following sections, we will get into more detail in order to better understand how the Definitive Dymension DM40 and PSB Imagine X2T 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 Dymension DM40 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.

Dymension DM40 features a 1" aluminum oxide 2 x Hard-Dome Tweeter and 4 x 4.5" Polypropelene Woofer . 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
Dymension DM40 has a frequency range of 55-23 kHz 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 Dymension DM40's min frequency of 55Hz.
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
Dymension DM40 is a 4 ohms speaker compared to the Imagine X2T which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Dymension DM40 can provide this impedance level.
These two speakers also have different sensitivity levels. Dymension DM40 sensitivity is rated at 87 dB and the Imagine X2T's is rated at 90 dB. This 3 dB difference makes the PSB Imagine X2T a more sensitive speaker compared to Definitive Dymension DM40, 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.
Dymension DM40 can handle a max power of 250 watts RMS from the amp the whereas Imagine X2T has a max power handling value of 200 watts RMS, 50 watts less than the Dymension DM40.
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. Dymension DM40 has a Binding post which doesn't feature bi-amping/bi-wiring.

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 Definitive Dymension DM40's and PSB Imagine X2T's external dimensions. Definitive Dymension DM40 has external dimensions of 950 x 261 x 255 mm ( 37.4 x 10.3 x 10.0 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) .
Definitive Dymension DM40 is 70mm shorter and 171mm less deeper than PSB Imagine X2T but it is also 32mm 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 Definitive Dymension DM40 is approximately 665.6cm2 / 103.2inch2 and base area of the PSB Imagine X2T is approximately 975.5cm2 / 151.2inch2. The Dymension DM40 requires 32% less surface area than the Imagine X2T which gives it a small advantage 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 Definitive Dymension DM40 weighs 17.30kg / 38.1lbs and the PSB Imagine X2T weighs 23.60kg / 51.9lbs. This makes the Imagine X2T 36% heavier than the Dymension DM40.
Here is a comparison of how Dymension DM40 and Imagine X2T's weights compare with the average, max and min weights in Passive Floor-standing class.
