What size room are the KEF R5 Meta and KEF R7 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:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the KEF R5 Meta and KEF R7 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

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. On the other hand, the R7 features a 1" aluminum Dome Tweeter , a 5" Midrange and 2 x 6.5" Hybrid Aluminum Woofer with a Crossover frequency at 400Hz and 2900Hz.
Frequency Response
R5 Meta has a frequency range of 52-28k Hz whereas R7 has a frequency range of 48-28k Hz. With a minimum frequency of 48Hz, the R7 can go slightly deeper then the R5 Meta'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
R5 Meta is a 4 ohms speaker compared to the R7 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 R5 Meta can provide this impedance level.
These two speakers also have different sensitivity levels. R5 Meta sensitivity is rated at 87 dB and the R7's is rated at 88 dB. This 1 dB difference makes the KEF R7 a more sensitive speaker compared to KEF R5 Meta, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing Speakers
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.
R5 Meta can handle a max power of 250 watts RMS from the amp the whereas R5 Meta has a max power handling value of 200 watts RMS , 50 watts less than the R7.
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 R5 Meta and R7 features dual binding post speaker terminals for 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
KEF R7's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both R5 Meta and R7 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 R5 Meta's and KEF R7's external dimensions. 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) whereas KEF R7 has external dimensions of 1113.0 x 200.0 x 389.0mm ( 43-13/16 x 8 x 15-5/16inch) .
KEF R5 Meta is 39mm shorter and 46mm less deeper than KEF R7 but it is also 74mm wider.
Below you can see the front view size comparison of KEF R5 Meta and KEF R7 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 R5 Meta is approximately 939.8cm2 / 145.7inch2 and base area of the KEF R7 is approximately 778.0cm2 / 120.6inch2. The R5 Meta requires 21% more surface area than the R7 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 R5 Meta weighs 24.55kg / 54lbs and the KEF R7 weighs 31.40kg / 69.1lbs. This makes the R7 28% heavier than the R5 Meta.
Here is a comparison of how R5 Meta and R7's weights compare with the average, max and min weights in Passive Floor-standing class.
