In this review, we will be comparing R7 Meta and Reference 3 Meta, two Passive Floor-standing speakers by KEF Let's have a brief look at the main features
of KEF R7 Meta and KEF Reference 3 Meta first before getting into our more
detailed comparison.
What size room are the KEF R7 Meta and KEF Reference 3 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 R7 Meta and KEF Reference 3 Meta compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

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 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.
Frequency Response
R7 Meta has a frequency range of 48-28k Hz whereas Reference 3 Meta has a frequency range of 43-35k Hz. With a minimum frequency of 43Hz, the Reference 3 Meta can go significantly deeper on the low side and provide stronger bass compared to the R7 Meta's min frequency of 48Hz.
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
R7 Meta and Reference 3 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 Reference 3 Meta's is at 86 dB. This 2 dB difference makes the KEF R7 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 R7 Meta and the R7 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.
R7 Meta can handle a max power of 300 watts RMS from the amp the whereas R7 Meta has a max power handling value of 250 watts RMS , 50 watts less than the Reference 3 Meta.
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 R7 Meta and Reference 3 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 Reference 3 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 Reference 3 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 R7 Meta's and KEF Reference 3 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 Reference 3 Meta has external dimensions of 1207 x 323 x 467 mm ( 47.5 x 12.7 x 18.4 in.) .
KEF Reference 3 Meta is clearly the larger of the two speakers. Its body is 11mm wider, 95mm taller and 82mm deeper than KEF R7 Meta.
Below you can see the front view size comparison of KEF R7 Meta and KEF Reference 3 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 Reference 3 Meta is approximately 1508.4cm2 / 233.8inch2. The R7 Meta requires 20% less surface area than the Reference 3 Meta 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 R7 Meta weighs 29.36kg / 64.6lbs and the KEF Reference 3 Meta weighs 51.30kg / 112.9lbs. This makes the Reference 3 Meta 75% heavier than the R7 Meta.
Here is a comparison of how R7 Meta and Reference 3 Meta's weights compare with the average, max and min weights in Passive Floor-standing class.
