What size room are the Monitor Audio Silver 500 7G 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:

position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.

Silver 500 7G features a 1" gold dome C-CAM with Uniform Dispersion (UD) Waveguide II Tweeter, a 3" Midrange and 2 x 8" C-CAM RST II Woofer. 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
Silver 500 7G has a frequency range of 27-35k Hz whereas R7 has a frequency range of 48-28k Hz. With a minimum frequency of 27Hz, the Silver 500 7G can go significantly deeper on the low side and provide stronger bass compared to the R7's min frequency of 48Hz.
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
Silver 500 7G and R7 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Silver 500 7G sensitivity is rated at 90.5 dB and the R7's is at 88 dB. This 3 dB difference makes the Monitor Audio Silver 500 7G a more sensitive speaker compared to KEF R7, 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Both handle the same maximum of 250 watts RMS, though Silver 500 7G is rated 80-250 watts and R7 15-250 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.
Monitor Audio Silver 500 7G
Input Type and Bi-Amping / Bi-Wiring
Both Silver 500 7G and R7 features dual binding post speaker terminals for bi-amping or bi-wiring.
KEF R7's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Silver 500 7G 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
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 Monitor Audio Silver 500 7G's and KEF R7's external dimensions. Monitor Audio Silver 500 7G has external dimensions of 1085.0 x 323.0 x 393.0mm (42-11/16 x 12-11/16 x 15-7/16inch) 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 R7 is 123mm narrower and 4mm less deeper than Monitor Audio Silver 500 7G but it is also 28mm taller.
Below you can see the front view size comparison of Monitor Audio Silver 500 7G 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 Monitor Audio Silver 500 7G is approximately 1269.4cm2 / 196.8inch2 and base area of the KEF R7 is approximately 778.0cm2 / 120.6inch2. The Silver 500 7G requires 63% 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 Monitor Audio Silver 500 7G weighs 22.53kg / 49.6lbs and the KEF R7 weighs 31.40kg / 69.1lbs. This makes the R7 39% heavier than the Silver 500 7G.
Here is a comparison of how Silver 500 7G and R7's weights compare with the average, max and min weights in Passive Floor-standing class.

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.
| Area | Better | Why |
|---|
| Bass | A | Monitor Audio Silver 500 7G digs deeper - 27Hz against 48Hz. |
| Amplifier needs | A | Monitor Audio Silver 500 7G is more sensitive (91dB vs 88dB), so it goes louder on the same amplifier. |
| Headroom | evenly matched | Similar power handling (250W vs 250W). |
| Size | depends | KEF R7 is easier to place; Monitor Audio Silver 500 7G is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Monitor Audio Silver 500 7G: bi-amping; KEF R7: bi-amping. Monitor Audio Silver 500 7G sits in a wider range (8 models), so a matched surround system is easier later. |
| Price | A | Monitor Audio Silver 500 7G is cheaper - $3,200 against $4,500, about 29% less. |
A Monitor Audio Silver 500 7G B KEF R7
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?
Monitor Audio Silver 500 7G is the easier recommendation: it leads on most of the measured areas and costs less. Take KEF R7 if its size, looks or fit in your room suit you better. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 48Hz anyway, so judge these on the other rows instead. In a large or open-plan room, Monitor Audio Silver 500 7G has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, KEF R7 is the easier speaker to get right.
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.
