Drivers
One of the fundamental differences between these two speakers is that Sonus faber Sonetto III G2 is a -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.

Sonus faber Sonetto III G2 features a 1.1" Soft-dome Tweeter and 2 x 6.5" Paper Pulp Woofer . On the other hand, the Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer .
Frequency Response
Sonus faber Sonetto III G2 has a frequency range of 38-40k 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 Sonus faber Sonetto III G2's min frequency of 38Hz.
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
Sonus faber Sonetto III G2 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 Sonus faber Sonetto III G2 can provide this impedance level.
These two speakers also have different sensitivity levels. Sonus faber Sonetto III G2 sensitivity is rated at 88 dB and the Concord's is rated at 94 dB. This 6 dB difference makes the KLH Concord a more sensitive speaker compared to Sonus faber Sonetto III G2, 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.
Sonus faber Sonetto III G2 can handle a max power of 280 watts RMS from the amp the whereas Concord has a max power handling value of watts RMS, 280 watts less than the Sonus faber Sonetto III G2.
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
Sonus faber Sonetto III G2 features Binding 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 Sonus faber Sonetto III G2's and KLH Concord's external dimensions. Sonus faber Sonetto III G2 has external dimensions of 1069.0 x 288.0 x 364.0mm ( 42-1/16inch x 11-5/16inch x 14-5/16inch ) 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) .
KLH Concord is 76mm narrower and 43mm shorter than Sonus faber Sonetto III G2 but it is also 16mm deeper.
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 Sonus faber Sonetto III G2 is approximately 1048.3cm2 / 162.5inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The Sonus faber Sonetto III G2 requires 30% 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 Sonus faber Sonetto III G2 weighs 25.85kg / 56.9lbs and the KLH Concord weighs 20.45kg / 45lbs. This makes the Sonus faber Sonetto III G2 26% heavier than the Concord.
