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

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 46-28k Hz. With a minimum frequency of 43Hz, the Reference 3 Meta can go slightly deeper then the R11 Meta's min frequency of 46Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Both handle the same maximum of 300 watts RMS, though Reference 3 Meta is rated 50-300 watts and R11 Meta 15-300 watts.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
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
The size of a speaker can sometimes be 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.

These sit in different price classes - KEF Reference 3 Meta costs roughly 2.3x what KEF R11 Meta does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | A | KEF Reference 3 Meta digs deeper - 43Hz against 46Hz. A subwoofer would even that out. |
| Amplifier needs | B | KEF R11 Meta is more sensitive (90dB vs 86dB), so it goes louder on the same amplifier. |
| Headroom | evenly matched | Similar power handling (300W vs 300W). |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | KEF Reference 3 Meta: bi-amping; KEF R11 Meta: bi-amping. |
| Price | B | KEF R11 Meta is cheaper - $6,498 against $15,000, about 57% less; arguably a different class. |
A KEF Reference 3 Meta B KEF R11 Meta
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. If your amplifier is modest, vintage or valve-based, KEF R11 Meta is the safer partner - the other will want more current or more watts to sound its best. Think about the whole system, not just the speakers: the roughly $8,502 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
