Blade One Meta features a 1" aluminium dome with MAT Tweeter, a 5" Midrange and 4 x 9" aluminium cone Woofer with a Crossover frequency at 350Hz and 2000Hz. 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
Blade One Meta has a frequency range of 35-35k 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 Blade One Meta's min frequency of 35Hz.
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
Blade One 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 Blade One Meta can provide this impedance level.
These two speakers also have different sensitivity levels. Blade One Meta sensitivity is rated at 88 dB and the Silver 500 7G's is rated at 90.5 dB. This 3 dB difference makes the Monitor Audio Silver 500 7G a more sensitive speaker compared to KEF Blade One 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.
Blade One Meta can handle a max power of 400 watts RMS, whereas Silver 500 7G has a max power handling value of 250 watts RMS, 150 watts less than the Blade One 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.

Starting with a popular amplifier — change it to the one you own, or any you are
considering, and watch both numbers move.

Input Type and Bi-Amping / Bi-Wiring
Silver 500 7G features Binding post posts which make bi-amping or bi-wiring possible. Blade One Meta has a Binding posts which doesn't feature bi-amping/bi-wiring.
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 Blade One Meta's and Monitor Audio Silver 500 7G's external dimensions. KEF Blade One Meta has external dimensions of 1590 x 363 x 540 mm (62.5 x 14.3 x 21.2 in.) 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 Blade One Meta is clearly the larger of the two speakers. Its body is 40mm wider, 505mm taller and 147mm deeper than Monitor Audio Silver 500 7G.
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 Blade One Meta is approximately 1960.2cm2 / 303.8inch2 and base area of the Monitor Audio Silver 500 7G is approximately 1269.4cm2 / 196.8inch2. The Blade One Meta requires 54% more surface area than the Silver 500 7G 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 KEF Blade One Meta weighs 57.20kg / 125.8lbs and the Monitor Audio Silver 500 7G weighs 22.53kg / 49.6lbs. This makes the Blade One Meta 154% heavier than the Silver 500 7G.
Here is a comparison of how Blade One 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 Blade One Meta costs roughly 10.9x 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 35Hz. A subwoofer would even that out. |
| Amplifier needs |
B |
Monitor Audio Silver 500 7G is more sensitive (91dB vs 88dB), so it goes louder on the same amplifier. |
| 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 |
A |
KEF Blade One Meta takes more power (400W vs 250W) - more in hand in a big room. |
| Size |
depends |
Monitor Audio Silver 500 7G is easier to place; KEF Blade One Meta is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability |
B |
Monitor Audio Silver 500 7G: bi-amping. Monitor Audio Silver 500 7G sits in a wider range (8 models), so a matched surround system is easier later. |
| Price |
B |
Monitor Audio Silver 500 7G is cheaper - $3,200 against $35,000, about 91% less; arguably a different class. |

B Monitor Audio Silver 500 7G
depends neither is better in the abstract - it turns on your room, placement 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 Blade One 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 35Hz anyway, so judge these on the other rows instead. Match it to your room: we rate KEF Blade One 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.
