In this review, we will be comparing Imagine X1T and Concord, two Passive Floor-standing speakers from PSB and KLH. Let's have a brief look at the main features
of PSB Imagine X1T and KLH Concord first before getting into our more
detailed comparison.
In the following sections, we will get into more detail in order to better understand how the PSB Imagine X1T and KLH Concord compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Imagine X1T features a 1" titanium with neodymium magnets Dome Tweeter and 2 x 5.25" Clay/Ceramic/Poly Woofer with a Crossover frequency at 1800Hz. On the other hand, the Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer .
Frequency Response
Imagine X1T has a frequency range of 35-23k Hz whereas Concord has a frequency range of 28-23k Hz. With a minimum frequency of 28Hz, the Concord can go significantly deeper on the low side and provide stronger bass compared to the Imagine X1T's min frequency of 35Hz.
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 X1T and Concord have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Imagine X1T sensitivity is rated at 90 dB and the Concord's is at 94 dB. This 4 dB difference makes the KLH Concord a more sensitive speaker compared to PSB Imagine X1T, 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 X1T can handle a max power of 200 watts RMS from the amp the whereas Concord has a max power handling value of watts RMS, 200 watts less than the Imagine X1T.
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 X1T features 5-Way post posts which make bi-amping or bi-wiring possible. Concord has a 5-Way 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 PSB Imagine X1T's and KLH Concord's external dimensions. PSB Imagine X1T has external dimensions of 877.0 x 210.0 x 378.0mm ( 34-1/2 x 8-1/4 x 14-7/8inch) whereas KLH Concord has external dimensions of 1026.0 x 212.0 x 380.0mm ( 40-3/8 x 8-5/16 x 14-15/16inch) .
KLH Concord is clearly the larger of the two speakers. Its body is 2mm wider, 149mm taller and 2mm deeper than PSB Imagine X1T.
Below you can see the front view size comparison of PSB Imagine X1T and KLH Concord 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 X1T is approximately 793.8cm2 / 123.0inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The Imagine X1T requires 1% less surface area than the Concord 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 PSB Imagine X1T weighs 17.30kg / 38.1lbs and the KLH Concord weighs 20.45kg / 45lbs. This makes the Concord 18% heavier than the Imagine X1T.
Here is a comparison of how Imagine X1T and Concord's weights compare with the average, max and min weights in Passive Floor-standing class.
