R11 Meta features a 1" Aluminum with MAT absorber Vented dome Tweeter, a 5" Midrange and 4 x 6.5" Hybrid Aluminum Woofer with a Crossover frequency at 330Hz and 2500Hz. On the other hand, the 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.
Frequency Response
R11 Meta has a frequency range of 46-28k Hz whereas Silver 500 7G has a frequency range of 27-35k 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 R11 Meta's min frequency of 46Hz.
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
R11 Meta is a 4 ohms speaker compared to the Silver 500 7G 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 R11 Meta can provide this impedance level.
These two speakers also have different sensitivity levels. R11 Meta sensitivity is rated at 90 dB and the Silver 500 7G's is rated at 90.5 dB. This 1 dB difference makes the Monitor Audio Silver 500 7G a more sensitive speaker compared to KEF R11 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
R11 Meta can handle a max power of 300 watts RMS, whereas Silver 500 7G has a max power handling value of 250 watts RMS, 50 watts less than the R11 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.
Monitor Audio Silver 500 7G
Input Type and Bi-Amping / Bi-Wiring
Both R11 Meta and Silver 500 7G features dual binding post speaker terminals for bi-amping or bi-wiring.
KEF R11 Meta's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both R11 Meta and Silver 500 7G 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 R11 Meta's and Monitor Audio Silver 500 7G's external dimensions. KEF R11 Meta has external dimensions of 1296.0 x 312.0 x 385.0mm (51-inch x 12-1/4-inch x 15-1/8-inch) whereas 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).
KEF R11 Meta is 11mm narrower and 8mm less deeper than Monitor Audio Silver 500 7G but it is also 211mm taller.
Below you can see the front view size comparison of KEF R11 Meta and Monitor Audio Silver 500 7G 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 R11 Meta is approximately 1201.2cm2 / 186.2inch2 and base area of the Monitor Audio Silver 500 7G is approximately 1269.4cm2 / 196.8inch2. The R11 Meta requires 5% less surface area than the Silver 500 7G 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 R11 Meta weighs 36.59kg / 80.5lbs and the Monitor Audio Silver 500 7G weighs 22.53kg / 49.6lbs. This makes the R11 Meta 62% heavier than the Silver 500 7G.
Here is a comparison of how R11 Meta and Silver 500 7G's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - KEF R11 Meta costs roughly 2x what Monitor Audio Silver 500 7G does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | B | Monitor Audio Silver 500 7G digs deeper - 27Hz against 46Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (90dB vs 91dB) - both want much the same power. |
| Amplifier match | B | Monitor Audio Silver 500 7G is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | evenly matched | Similar power handling (300W vs 250W). |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | KEF R11 Meta: bi-amping; Monitor Audio Silver 500 7G: bi-amping. |
| Price | B | Monitor Audio Silver 500 7G is cheaper - $3,200 against $6,498, about 51% less; arguably a different class. |
A KEF R11 Meta B Monitor Audio Silver 500 7G
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 R11 Meta 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 46Hz anyway, so judge these on the other rows instead. Match it to your room: we rate KEF R11 Meta the better fit for a very large room; elsewhere the two are rated the same.
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.
