3050c features a 0.9" decoupled Tweeter and 2 x 5.5" Coated paper Woofer with a Crossover frequency at 2400 Hz. On the other hand, the Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer .
Frequency Response
3050c has a frequency range of 42-30k 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 3050c's min frequency of 42Hz.
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
3050c is a 6 ohms speaker compared to the Concord which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. 3050c 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 Q Acoustics 3050c, 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.
3050c can handle a max power of 150 watts RMS from the amp the whereas Concord has a max power handling value of watts RMS, 150 watts less than the 3050c.
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
3050c 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 3050c's and KLH Concord's external dimensions. Q Acoustics 3050c has external dimensions of 1020 x 315 x 316 mm ( 40.2 x 12.4 x 12.4 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) .
Q Acoustics 3050c is 6mm shorter and 64mm less deeper than KLH Concord but it is also 103mm wider.
Below you can see the front view size comparison of Q Acoustics 3050c and KLH Concord 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 Q Acoustics 3050c is approximately 995.4cm2 / 154.3inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The 3050c requires 24% 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 3050c weighs 17.80kg / 39.2lbs and the KLH Concord weighs 20.45kg / 45lbs. This makes the Concord 15% heavier than the 3050c.
Here is a comparison of how 3050c and Concord's weights compare with the average, max and min weights in Passive Floor-standing class.
