In this review, we will be comparing Concord and C 97 II, two Passive Floor-standing speakers from KLH and Jamo. Let's have a brief look at the main features
of KLH Concord and Jamo C 97 II 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 KLH Concord and Jamo C 97 II 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 Concord is a 2-way design whereas the C 97 II 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.

Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer . On the other hand, the C 97 II features a 1" Tweeter , a 6" Midrange and 3 x 6" Composite Woofer .
Frequency Response
Concord has a frequency range of 28-23k Hz whereas C 97 II has a frequency range of 32-24k Hz. With a minimum frequency of 28Hz, the Concord can go slightly deeper then the C 97 II's min frequency of 32Hz.
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
Concord is a 8 ohms speaker compared to the C 97 II which has a nominal impedance of 6 ohms.
These two speakers also have different sensitivity levels. Concord sensitivity is rated at 94 dB and the C 97 II's is rated at 89 dB. This 5 dB difference makes the KLH Concord a more sensitive speaker compared to Jamo C 97 II, 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.
Concord can handle a max power of 180 watts RMS from the amp the whereas Concord has a max power handling value of watts RMS , 180 watts less than the C 97 II.
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
C 97 II features 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 KLH Concord's and Jamo C 97 II's external dimensions. 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) whereas Jamo C 97 II has external dimensions of 1070.0 x 248.0 x 402.0mm ( 42-1/8 x 9-3/4 x 15-13/16inch) .
Jamo C 97 II is clearly the larger of the two speakers. Its body is 36mm wider, 44mm taller and 22mm deeper than KLH Concord.
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 KLH Concord is approximately 805.6cm2 / 124.9inch2 and base area of the Jamo C 97 II is approximately 997.0cm2 / 154.5inch2. The Concord requires 19% less surface area than the C 97 II 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 KLH Concord weighs 20.45kg / 45lbs and the Jamo C 97 II weighs 24.55kg / 54lbs. This makes the C 97 II 20% heavier than the Concord.
Here is a comparison of how Concord and C 97 II's weights compare with the average, max and min weights in Passive Floor-standing class.
