Drivers
One of the fundamental differences between these two speakers is that Debut 3.0 DF63 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.

Debut 3.0 DF63 features a 1" Hard-Dome Tweeter , a 6.5" Midrange and 2 x 6.5" Aramid fiber Woofer with a Crossover frequency at 550Hz and 2000Hz. On the other hand, the Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer .
Frequency Response
Debut 3.0 DF63 has a frequency range of 31 to 38K Hz whereas Concord has a frequency range of 28-23k Hz. With a minimum frequency of 28Hz, the Concord can go slightly deeper then the Debut 3.0 DF63's min frequency of 31Hz.
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
Debut 3.0 DF63 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 Debut 3.0 DF63 can provide this impedance level.
These two speakers also have different sensitivity levels. Debut 3.0 DF63 sensitivity is rated at 87.5 dB and the Concord's is rated at 94 dB. This 6 dB difference makes the KLH Concord a more sensitive speaker compared to ELAC Debut 3.0 DF63, 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.
Debut 3.0 DF63 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 Debut 3.0 DF63.
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
Debut 3.0 DF63 features 5-Way post type posts and Concord has a 5-Way 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 ELAC Debut 3.0 DF63's and KLH Concord's external dimensions. ELAC Debut 3.0 DF63 has external dimensions of 1094.0 x 245.0 x 320.0mm ( 43-1/16-inch x 9-5/8-inch x 12-9/16-inch) 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 33mm narrower and 68mm shorter than ELAC Debut 3.0 DF63 but it is also 60mm 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 ELAC Debut 3.0 DF63 is approximately 784.0cm2 / 121.5inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The Debut 3.0 DF63 requires 3% less surface area than the Concord which gives it a small advantage on placement in tight spaces.
