In this review, we will be comparing Motion 60XTi and Concord, two Passive Floor-standing speakers from MartinLogan and KLH. Let's have a brief look at the main features
of MartinLogan 60XTi 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 MartinLogan 60XTi and KLH Concord 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 Motion 60XTi is a 3-way design whereas the Concord 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.

Motion 60XTi features a 1.25 x 2.4" Folded Motion XT Tweeter , a 6.5" Midrange and 2 x 8" Aluminum Woofer with a Crossover frequency at 400Hz and 2200Hz. On the other hand, the Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer .
Frequency Response
Motion 60XTi has a frequency range of 35-25k 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 Motion 60XTi'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
Motion 60XTi is a 4 ohms speaker compared to the Concord 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 Motion 60XTi can provide this impedance level.
On the other hand, they have the same sensitivity of 94 dBdB.

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.
Motion 60XTi can handle a max power of 400 watts RMS from the amp the whereas Concord has a max power handling value of watts RMS, 400 watts less than the Motion 60XTi.
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
Motion 60XTi features Custom 5-way bi-wire tool-less binding posts 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 MartinLogan 60XTi's and KLH Concord's external dimensions. MartinLogan 60XTi has external dimensions of 1174.0 x 231.0 x 396.0mm ( 46-3/16 x 9-1/16 x 15-9/16inch) 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) .
MartinLogan 60XTi is clearly the larger of the two speakers. Its body is 19mm wider, 148mm taller and 16mm deeper than KLH Concord.
Below you can see the front view size comparison of MartinLogan 60XTi 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 MartinLogan 60XTi is approximately 914.8cm2 / 141.8inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The Motion 60XTi requires 14% more surface area than the Concord 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 MartinLogan 60XTi weighs 30.00kg / 66lbs and the KLH Concord weighs 20.45kg / 45lbs. This makes the Motion 60XTi 47% heavier than the Concord.
Here is a comparison of how Motion 60XTi and Concord's weights compare with the average, max and min weights in Passive Floor-standing class.
