In this review, we will be comparing Imagine X2T and BW 603, two Passive Floor-standing speakers from PSB and Bowers Wilkins. Let's have a brief look at the main features
of PSB Imagine X2T and B&W 603 first before getting into our more
detailed comparison.
What size room are the PSB Imagine X2T and B&W 603 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 PSB Imagine X2T and B&W 603 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

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 BW 603 features a 1" Tweeter , a 6" Midrange and 2 x 6.5" Paper Woofer .
Frequency Response
Imagine X2T has a frequency range of 30-23k Hz whereas BW 603 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 BW 603'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.

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 BW 603 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 BW 603's is at 88.5 dB. This 1 dB difference makes the PSB Imagine X2T a more sensitive speaker compared to B&W 603, 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.
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
Both Imagine X2T and BW 603 features dual binding post speaker terminals for bi-amping or bi-wiring.
PSB Imagine X2T's 5-Way post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Imagine X2T has a front firing port whereas BW 603 has a rear firing ports. PSB Imagine X2T's front-firing port gives more flexibility in placement in regards to proximity to walls compared to B&W 603 with its rear-firing port.
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 B&W 603'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 B&W 603 has external dimensions of 985.0 x 190.0 x 340.0mm ( 38.7 x 7.4 x 13.3inch) .
PSB Imagine X2T is clearly the larger of the two speakers. Its body is 39mm wider, 35mm taller and 86mm deeper than B&W 603.
Below you can see the front view size comparison of PSB Imagine X2T and B&W 603 in scale.

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 B&W 603 is approximately 646.0cm2 / 100.1inch2. The Imagine X2T requires 51% more surface area than the BW 603 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 PSB Imagine X2T weighs 23.60kg / 51.9lbs and the B&W 603 weighs 24.14kg / 53.1lbs. This makes the BW 603 2% heavier than the Imagine X2T.
Here is a comparison of how Imagine X2T and BW 603's weights compare with the average, max and min weights in Passive Floor-standing class.
