In this review, we will be comparing Concord and Oberon 9, two Passive Floor-standing speakers from KLH and DALI. Let's have a brief look at the main features
of KLH Concord and DALI Oberon 9 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 DALI Oberon 9 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 Oberon 9 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 Oberon 9 features a 1.125" Soft-Dome Tweeter , a 7" Midrange and 2 x 9" Wood Fiber Woofer with a Crossover frequency at 780Hz and 3400Hz.
Frequency Response
Concord has a frequency range of 28-23k Hz whereas Oberon 9 has a frequency range of 35-26k Hz. With a minimum frequency of 28Hz, the Concord can go significantly deeper on the low side and provide stronger bass compared to the Oberon 9'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.

High Frequency
Floor-standing Speakers
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 Oberon 9 which has a nominal impedance of 4 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 Oberon 9 can provide this impedance level.
These two speakers also have different sensitivity levels. Concord sensitivity is rated at 94 dB and the Oberon 9's is rated at 90.5 dB. This 3 dB difference makes the KLH Concord a more sensitive speaker compared to DALI Oberon 9, 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 400 watts RMS from the amp the whereas Concord has a max power handling value of watts RMS , 400 watts less than the Oberon 9.
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
Concord features Post type posts and Oberon 9 has a Post type posts. None of these speakers 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 DALI Oberon 9'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 DALI Oberon 9 has external dimensions of 1172.0 x 260.0 x 407.0mm ( 46-1/8 x 10-1/4 x 16inch) .
DALI Oberon 9 is clearly the larger of the two speakers. Its body is 48mm wider, 146mm taller and 27mm deeper than KLH Concord.
Below you can see the front view size comparison of KLH Concord and DALI Oberon 9 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 KLH Concord is approximately 805.6cm2 / 124.9inch2 and base area of the DALI Oberon 9 is approximately 1058.2cm2 / 164.0inch2. The Concord requires 24% less surface area than the Oberon 9 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 DALI Oberon 9 weighs 37.10kg / 81.6lbs. This makes the Oberon 9 81% heavier than the Concord.
Here is a comparison of how Concord and Oberon 9's weights compare with the average, max and min weights in Passive Floor-standing class.
