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 R11 features a 1" aluminum Dome Tweeter , a 5" Midrange and 4 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 R11 has a frequency range of 46-28k 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 R11's min frequency of 46Hz.
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
Silver 500 7G and R11 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 R11's is at 90 dB. This 1 dB difference makes the Monitor Audio Silver 500 7G a more sensitive speaker compared to KEF R11, hence will play louder with the same amount of watts.

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.
Silver 500 7G can handle a max power of 300 watts RMS from the amp the whereas Silver 500 7G has a max power handling value of 250 watts RMS , 50 watts less than the R11.
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 Silver 500 7G and R11 features dual binding post speaker terminals for bi-amping or bi-wiring.
KEF R11's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Silver 500 7G and R11 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 Monitor Audio Silver 500 7G's and KEF R11'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 R11 has external dimensions of 1301.0 x 312.0 x 389.0mm ( 51-3/16 x 12-1/4 x 15-5/16inch) .
KEF R11 is 11mm narrower and 4mm less deeper than Monitor Audio Silver 500 7G but it is also 216mm taller.
Below you can see the front view size comparison of Monitor Audio Silver 500 7G and KEF R11 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 R11 is approximately 1213.7cm2 / 188.1inch2. The Silver 500 7G requires 5% more surface area than the R11 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 R11 weighs 37.70kg / 82.9lbs. This makes the R11 67% heavier than the Silver 500 7G.
Here is a comparison of how Silver 500 7G and R11's weights compare with the average, max and min weights in Passive Floor-standing class.
