R6 Meta features a 1" Aluminum with MAT absorber Hard-Dome Tweeter , a 5" Midrange and 2 x 6.5" Hybrid Aluminum Woofer with a Crossover frequency at 500Hz and 2400Hz. On the other hand, the R11 Meta features a 1" Aluminum with MAT absorber Vented dome Tweeter , a 5" Midrange and 4 x 6.5" Hybrid Aluminum Woofer with a Crossover frequency at 330Hz and 2500Hz.
Frequency Response
R6 Meta has a frequency range of 65-28k Hz whereas R11 Meta has a frequency range of 46-28 Hz. With a minimum frequency of 46Hz, the R11 Meta can go significantly deeper on the low side and provide stronger bass compared to the R6 Meta's min frequency of 65Hz.
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.

High Frequency

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
R6 Meta and R11 Meta have the same Impedance of 4 ohms but where they differ is the sensitivity levels. R6 Meta sensitivity is rated at 88 dB and the R11 Meta's is at 90 dB. This 2 dB difference makes the KEF R11 Meta a more sensitive speaker compared to KEF R6 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 R6 Meta and the R6 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.
R6 Meta can handle a max power of 300 watts RMS from the amp the whereas R6 Meta has a max power handling value of 250 watts RMS , 50 watts less than the R11 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
Both R6 Meta and R11 Meta features dual binding post speaker terminals for bi-amping or bi-wiring.
KEF R6 Meta's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
KEF R11 Meta's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or 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 R6 Meta's and KEF R11 Meta's external dimensions. KEF R6 Meta has external dimensions of 202.0 x 626.0 x 339.0mm ( 7-15/16-inch x 24-5/8-inch x 13-5/16-inch) whereas KEF R11 Meta has external dimensions of 1296.0 x 312.0 x 385.0mm ( 51-inch x 12-1/4-inch x 15-1/8-inch) .
KEF R6 Meta is 1094mm shorter and 46mm less deeper than KEF R11 Meta but it is also 314mm 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 R6 Meta is approximately 2122.1cm2 / 328.9inch2 and base area of the KEF R11 Meta is approximately 1201.2cm2 / 186.2inch2. The R6 Meta requires 77% more surface area than the R11 Meta which gives it a small disadvantage on placement in tight spaces.
