Drivers
One of the fundamental differences between these two speakers is that Dymension DM70 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.

Dymension DM70 features a 1" aluminum oxide 2 x Hard-Dome Tweeter , a 5.25" Midrange and 1 x 10" Polypropelene Woofer . On the other hand, the Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer .
Frequency Response
Dymension DM70 has a frequency range of 30-23 kHz whereas Concord has a frequency range of 28-23k Hz. With a minimum frequency of 28Hz, the Concord can go slightly deeper then the Dymension DM70's min frequency of 30Hz.
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.

Definitive Dymension DM70
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
Dymension DM70 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 Dymension DM70 can provide this impedance level.
These two speakers also have different sensitivity levels. Dymension DM70 sensitivity is rated at 90 dB and the Concord's is rated at 94 dB. This 4 dB difference makes the KLH Concord a more sensitive speaker compared to Definitive Dymension DM70, 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.
Dymension DM70 can handle a max power of 300 watts RMS from the amp the whereas Concord has a max power handling value of watts RMS, 300 watts less than the Dymension DM70.
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
Dymension DM70 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 Definitive Dymension DM70's and KLH Concord's external dimensions. Definitive Dymension DM70 has external dimensions of 1204 x 287 x 407 mm ( 47.4 x 11.3 x 16.0 in) 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) .
Definitive Dymension DM70 is clearly the larger of the two speakers. Its body is 75mm wider, 178mm taller and 27mm 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 Definitive Dymension DM70 is approximately 1168.1cm2 / 181.1inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The Dymension DM70 requires 45% more surface area than the Concord which gives it a small disadvantage on placement in tight spaces.
