R7 Meta and R5 Meta are members of KEF's R META series of speakers. Below you can find the loudspeakers from this series.
What size room are the KEF R7 Meta and KEF R5 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:

R7 Meta features a 1" Aluminum with MAT absorber Vented dome Tweeter, a 5" Midrange and 2 x 6.5" Hybrid Aluminum Woofer with a Crossover frequency at 400Hz and 2400Hz. On the other hand, the R5 Meta features a 1" Aluminum with MAT absorber Vented dome Tweeter, a 5" Midrange and 2 x 5.25" Hybrid Aluminum Woofer with a Crossover frequency at 400Hz and 2700Hz.
Frequency Response
R7 Meta has a frequency range of 48-28k Hz whereas R5 Meta has a frequency range of 52-28k Hz. With a minimum frequency of 48Hz, the R7 Meta can go slightly deeper then the R5 Meta's min frequency of 52Hz.
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
R7 Meta and R5 Meta have the same Impedance of 4 ohms but where they differ is the sensitivity levels. R7 Meta sensitivity is rated at 88 dB and the R5 Meta's is at 87 dB. This 1 dB difference makes the KEF R7 Meta a more sensitive speaker compared to KEF R5 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 R7 Meta and the R7 Meta can provide this impedance level.
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.
R7 Meta can handle a max power of 250 watts RMS, whereas R5 Meta has a max power handling value of 200 watts RMS, 50 watts less than the R7 Meta.
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 R7 Meta and R5 Meta features dual binding post speaker terminals for bi-amping or bi-wiring.
KEF R7 Meta's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
KEF R5 Meta's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both R7 Meta and R5 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 R7 Meta's and KEF R5 Meta's external dimensions. KEF R7 Meta has external dimensions of 1112.0 x 312.0 x 385.0mm (43-3/4-inch x 12-1/4-inch x 15-1/8-inch) whereas KEF R5 Meta has external dimensions of 1074.0 x 274.0 x 343.0mm (42-1/4-inch x 10-3/4-inch x 13-1/2-inch).
KEF R7 Meta is clearly the larger of the two speakers. Its body is 38mm wider, 38mm taller and 42mm deeper than KEF R5 Meta.
Below you can see the front view size comparison of KEF R7 Meta and KEF R5 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 R7 Meta is approximately 1201.2cm2 / 186.2inch2 and base area of the KEF R5 Meta is approximately 939.8cm2 / 145.7inch2. The R7 Meta requires 28% more surface area than the R5 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 R7 Meta weighs 29.36kg / 64.6lbs and the KEF R5 Meta weighs 24.55kg / 54lbs. This makes the R7 Meta 20% heavier than the R5 Meta.
Here is a comparison of how R7 Meta and R5 Meta's weights compare with the average, max and min weights in Passive Floor-standing class.

Siblings in KEF's R META series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | A | KEF R7 Meta digs deeper - 48Hz against 52Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (88dB vs 87dB) - both want much the same power. |
| Headroom | A | KEF R7 Meta takes more power (250W vs 200W) - more in hand in a big room. |
| Size | depends | KEF R5 Meta is easier to place; KEF R7 Meta is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | KEF R7 Meta: bi-amping; KEF R5 Meta: bi-amping. |
| Price | B | KEF R5 Meta is cheaper - $3,998 against $4,998, about 20% less. |
A KEF R7 Meta B KEF R5 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?
The usual trade-off: KEF R7 Meta measures better, KEF R5 Meta costs about about 25% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest.
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.
