In this review, we will be comparing Concept 500 and Concord, two Passive Floor-standing speakers from Q Acoustics and KLH.
Let's have a brief look at the main features
of Q Acoustics Concept 500 and KLH Concord first before getting into our more
detailed comparison.

Concept 500 features a 1.1" Dome Tweeter and 2 x 6.5" Paper composite Woofer with a Crossover frequency at 2500Hz. On the other hand, the Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer .
Frequency Response
Concept 500 has a frequency range of 41-30k 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 Concept 500's min frequency of 41Hz.
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.
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.
Concept 500 can handle a max power of 200 watts RMS from the amp the whereas Concord has a max power handling value of watts RMS, 200 watts less than the Concept 500.
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
Concept 500 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 Q Acoustics Concept 500's and KLH Concord's external dimensions. Q Acoustics Concept 500 has external dimensions of 1175.0 x 400.0 x 375.0mm ( 46-1/4 x 15-3/4 x 14-3/4inch) 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 188mm narrower and 149mm shorter than Q Acoustics Concept 500 but it is also 5mm 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 Q Acoustics Concept 500 is approximately 1500.0cm2 / 232.5inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The Concept 500 requires 86% 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 Q Acoustics Concept 500 weighs 42.00kg / 92.4lbs and the KLH Concord weighs 20.45kg / 45lbs. This makes the Concept 500 105% heavier than the Concord.
Here is a comparison of how Concept 500 and Concord's weights compare with the average, max and min weights in Passive Floor-standing class.
