What size room are the KEF R11 Meta and KEF R11 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:

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. On the other hand, the R11 features a 1" aluminum Dome Tweeter, a 5" Midrange and 4 x 6.5" Hybrid Aluminum Woofer with a Crossover frequency at 400Hz and 2900Hz.
Frequency Response
R11 Meta and R11 has exactly the same frequency range of 46-28k Hz.
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
R11 Meta is a 4 ohms speaker compared to the R11 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 R11 Meta can provide this impedance level.
On the other hand, they have the same sensitivity of 90 dBdB.
Sensitivity
Floor-standing Speakers
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.
R11 Meta and R11 have the same power range of 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 R11 Meta and R11 features dual binding post speaker terminals for 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
KEF R11's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both R11 Meta and R11 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 R11 Meta's and KEF R11's external dimensions. 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) whereas KEF R11 has external dimensions of 1301.0 x 312.0 x 389.0mm (51-3/16 x 12-1/4 x 15-5/16inch).
Below you can see the front view size comparison of KEF R11 Meta and KEF R11 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 R11 Meta is approximately 1201.2cm2 / 186.2inch2 and base area of the KEF R11 is approximately 1213.7cm2 / 188.1inch2. The R11 Meta requires 1% less surface area than the R11 which gives it a small advantage 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 R11 Meta weighs 36.59kg / 80.5lbs and the KEF R11 weighs 37.70kg / 82.9lbs. This makes the R11 3% heavier than the R11 Meta.
Here is a comparison of how R11 Meta and R11's weights compare with the average, max and min weights in Passive Floor-standing class.

A generation apart: KEF R11 Meta is the newer design, against a 2018 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | evenly matched | Much the same reach (46Hz vs 46Hz). |
| Amplifier needs | evenly matched | Similar sensitivity (90dB vs 90dB) - both want much the same power. |
| Amplifier match | B | KEF R11 is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | evenly matched | Similar power handling (300W vs 300W). |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | KEF R11 Meta: bi-amping; KEF R11: bi-amping. |
| Price | evenly matched | Much the same money ($6,498 vs $6,000 a pair). |
A KEF R11 Meta B KEF R11
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?
KEF R11 has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. Match it to your room: we rate KEF R11 Meta the better fit for a very large room; elsewhere the two are rated the same. If your amplifier is modest, vintage or valve-based, KEF R11 is the safer partner - the other will want more current or more watts to sound its best.
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.
