Q6 Meta features a 0.75" vented aluminum dome with MAT absorber Hard-dome Tweeter , a 4" Midrange and 2 x 6.5" Aluminum Woofer with a Crossover frequency at 560 Hz, 2.7 kHz. On the other hand, the Q Concerto Meta features a 0.75" vented aluminum dome with MAT absorber Hard dome Tweeter , a 4" Midrange and 1 x 6.5" Aluminum Woofer with a Crossover frequency at 430 Hz, 2.9 kHz.
Frequency Response
Q6 Meta has a frequency range of 63-20k Hz whereas Q Concerto Meta has a frequency range of 48-20k Hz. With a minimum frequency of 48Hz, the Q Concerto Meta can go significantly deeper on the low side and provide stronger bass compared to the Q6 Meta's min frequency of 63Hz.
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 Center Channel class in our database.
Low Frequency

High Frequency
Center Channel 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
Q6 Meta and Q Concerto Meta have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Q6 Meta sensitivity is rated at 86 dB and the Q Concerto Meta's is at 85 dB. This 1 dB difference makes the KEF Q6 Meta a more sensitive speaker compared to KEF Q Concerto Meta, hence will play louder with the same amount of watts.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Q6 Meta and the Q6 Meta can provide this impedance level.

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.
Q6 Meta can handle a max power of 200 watts RMS from the amp the whereas Q Concerto Meta has a max power handling value of 180 watts RMS, 20 watts less than the Q6 Meta.
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
Q6 Meta features Binding Post type posts and Q Concerto Meta has a Binding 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 KEF Q6 Meta's and KEF Q Concerto Meta's external dimensions. KEF Q6 Meta has external dimensions of 210 x 629 x 303 mm ( 8.3 x 24.8 x 11.9 in.) whereas KEF Q Concerto Meta has external dimensions of 415 x 210 x 315 mm ( 16.3 x 8.3 x 12.4 in.) .
KEF Q6 Meta is 205mm shorter and 12mm less deeper than KEF Q Concerto Meta but it is also 419mm wider.
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 KEF Q6 Meta is approximately 1905.9cm2 / 295.4inch2 and base area of the KEF Q Concerto Meta is approximately 661.5cm2 / 102.5inch2. The Q6 Meta requires 188% more surface area than the Q Concerto Meta which gives it a small disadvantage on placement in tight spaces.
