Q11 Meta features a 0.75" vented aluminum dome with MAT absorber Hard dome Tweeter , a 4" Midrange and 3 x 6.5" Aluminum Woofer with a Crossover frequency at 480 Hz, 2.7 kHz. On the other hand, the R3 features a 1" aluminum Dome Tweeter , a 5" Midrange and 1 x 6.5" Hybrid aluminum Woofer with a Crossover frequency at 400Hz and 2900Hz.
Frequency Response
Q11 Meta has a frequency range of 44-20k Hz whereas R3 has a frequency range of 52-28k Hz. With a minimum frequency of 44Hz, the Q11 Meta can go significantly deeper on the low side and provide stronger bass compared to the R3's min frequency of 52Hz.
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.
Low Frequency
Floor-standing Speakers
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
Q11 Meta is a 4 ohms speaker compared to the R3 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 Q11 Meta can provide this impedance level.
These two speakers also have different sensitivity levels. Q11 Meta sensitivity is rated at 89 dB and the R3's is rated at 87 dB. This 2 dB difference makes the KEF Q11 Meta a more sensitive speaker compared to KEF R3, 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.
Q11 Meta can handle a max power of 225 watts RMS from the amp the whereas R3 has a max power handling value of 180 watts RMS, 45 watts less than the Q11 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
R3 features Binding post posts which make bi-amping or bi-wiring possible. Q11 Meta has a Binding Post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both Q11 Meta and R3 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.

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 Q11 Meta's and KEF R3's external dimensions. KEF Q11 Meta has external dimensions of 1112 x 317 x 380 mm ( 43.8 x 12.5 x 15.0 in.) whereas KEF R3 has external dimensions of 423.0 x 199.0 x 337.0mm ( 16-5/8 x 7-13/16 x 13-1/4inch) .
KEF Q11 Meta is clearly the larger of the two speakers. Its body is 118mm wider, 689mm taller and 43mm deeper than KEF R3.
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 Q11 Meta is approximately 1204.6cm2 / 186.7inch2 and base area of the KEF R3 is approximately 670.6cm2 / 103.9inch2. The Q11 Meta requires 80% more surface area than the R3 which gives it a small disadvantage on placement in tight spaces.
