In this review, we will be comparing Reference 3 Meta and R11 Meta, two Passive Floor-standing speakers by KEF Let's have a brief look at the main features
of KEF Reference 3 Meta and KEF R11 Meta first before getting into our more
detailed comparison.
What size room are the KEF Reference 3 Meta and KEF R11 Meta speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the KEF Reference 3 Meta and KEF R11 Meta compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Reference 3 Meta features a 1" aluminium dome with MAT Tweeter , a 5" Midrange and 2 x 6.5" aluminium cone Woofer with a Crossover frequency at 450Hz and 2100Hz. 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
Reference 3 Meta has a frequency range of 43-35k Hz whereas R11 Meta has a frequency range of 46-28 Hz. With a minimum frequency of 43Hz, the Reference 3 Meta can go slightly deeper then the R11 Meta's min frequency of 46Hz.
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.

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
Reference 3 Meta and R11 Meta have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Reference 3 Meta sensitivity is rated at 86 dB and the R11 Meta's is at 90 dB. This 4 dB difference makes the KEF R11 Meta a more sensitive speaker compared to KEF Reference 3 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 Reference 3 Meta and the Reference 3 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.
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 Reference 3 Meta and R11 Meta features dual binding post speaker terminals for bi-amping or bi-wiring.
KEF Reference 3 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
Cabinet Type and Port Position
Both Reference 3 Meta and R11 Meta 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 Reference 3 Meta's and KEF R11 Meta's external dimensions. KEF Reference 3 Meta has external dimensions of 1207 x 323 x 467 mm ( 47.5 x 12.7 x 18.4 in.) 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 R11 Meta is 11mm narrower and 82mm less deeper than KEF Reference 3 Meta but it is also 89mm taller.
Below you can see the front view size comparison of KEF Reference 3 Meta and KEF R11 Meta 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 KEF Reference 3 Meta is approximately 1508.4cm2 / 233.8inch2 and base area of the KEF R11 Meta is approximately 1201.2cm2 / 186.2inch2. The Reference 3 Meta requires 26% more surface area than the R11 Meta 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 KEF Reference 3 Meta weighs 51.30kg / 112.9lbs and the KEF R11 Meta weighs 36.59kg / 80.5lbs. This makes the Reference 3 Meta 40% heavier than the R11 Meta.
Here is a comparison of how Reference 3 Meta and R11 Meta's weights compare with the average, max and min weights in Passive Floor-standing class.
