What size room are the KEF R7 Meta and KEF Q950 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 R7 Meta and KEF Q950 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that R7 Meta is a 3-way design whereas the Q950 is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

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 Q950 features a 1.5" vented aluminum Dome Tweeter and 2 x 8.0" Aluminum Woofer with a Crossover frequency at 2200Hz.
Frequency Response
R7 Meta has a frequency range of 48-28k Hz whereas Q950 has a frequency range of 44-28k Hz. With a minimum frequency of 44Hz, the Q950 can go slightly deeper then 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.
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
R7 Meta is a 4 ohms speaker compared to the Q950 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 R7 Meta can provide this impedance level.
These two speakers also have different sensitivity levels. R7 Meta sensitivity is rated at 88 dB and the Q950's is rated at 91 dB. This 3 dB difference makes the KEF Q950 a more sensitive speaker compared to KEF R7 Meta, hence will play louder with the same amount of watts.

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 250 watts RMS from the amp the whereas Q950 has a max power handling value of 200 watts RMS, 50 watts less than the R7 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
R7 Meta features Custom 5-way bi-wire tool-less binding posts posts which make bi-amping or bi-wiring possible. Q950 has a Binding post which doesn't feature bi-amping/bi-wiring.
KEF R7 Meta's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
R7 Meta has a rear firing port whereas Q950 has a front firing ports. KEF Q950's front-firing port gives more flexibility in placement in regards to proximity to walls compared to KEF R7 Meta with its rear-firing port.
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 Q950'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 Q950 has external dimensions of 1117.0 x 362.0 x 315.0mm ( 43-15/16 x 14-1/4 x 12-3/8inch) .
KEF R7 Meta is 50mm narrower and 5mm shorter than KEF Q950 but it is also 70mm deeper.
Below you can see the front view size comparison of KEF R7 Meta and KEF Q950 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 Q950 is approximately 1140.3cm2 / 176.7inch2. The R7 Meta requires 5% more surface area than the Q950 which gives it a small disadvantage on placement in tight spaces.
