Walmer 2 features a 0.47x1.77" Ribbon True Ribbon Tweeter, a 4.5" Midrange and 2 x 6.5" Woven Carbon Fibre Woofer with a Crossover frequency at 350 Hz / 3.5 kHz. 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
Walmer 2 has a frequency range of 38-20k 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 Walmer 2's min frequency of 38Hz.
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
Walmer 2 and Silver 500 7G have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Walmer 2 sensitivity is rated at 89 dB and the Silver 500 7G's is at 90.5 dB. This 2 dB difference makes the Monitor Audio Silver 500 7G a more sensitive speaker compared to Castle Walmer 2, 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.
Silver 500 7G can handle a max power of 250 watts RMS, whereas Walmer 2 has a max power handling value of 150 watts RMS, 100 watts less than the Silver 500 7G.
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
Silver 500 7G features Binding post posts which make bi-amping or bi-wiring possible. Walmer 2 has a Binding post 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 Castle Walmer 2's and Monitor Audio Silver 500 7G's external dimensions. Castle Walmer 2 has external dimensions of 1170.0 x 250.0 x 370.0mm (46-1/16 x 9-13/16 x 14-9/16inch) 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).
Castle Walmer 2 is 73mm narrower and 23mm less deeper than Monitor Audio Silver 500 7G but it is also 85mm taller.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Monitor Audio Silver 500 7G needs about 37% more floor or shelf area. Monitor Audio Silver 500 7G is 23mm deeper, so it stands that much further out from the wall. Castle Walmer 2 is 85mm taller.
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 Castle Walmer 2 is approximately 925.0cm2 / 143.4inch2 and base area of the Monitor Audio Silver 500 7G is approximately 1269.4cm2 / 196.8inch2. The Walmer 2 requires 27% 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 Castle Walmer 2 weighs 31.00kg / 68.2lbs and the Monitor Audio Silver 500 7G weighs 22.53kg / 49.6lbs. This makes the Walmer 2 38% heavier than the Silver 500 7G.
Here is a comparison of how Walmer 2 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 - Castle Walmer 2 costs roughly 2.3x 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 38Hz. |
| Amplifier needs | B | Monitor Audio Silver 500 7G is more sensitive (91dB vs 89dB), so it goes louder on the same amplifier. |
| Headroom | B | Monitor Audio Silver 500 7G takes more power (250W vs 150W) - more in hand in a big room. |
| Size | depends | Castle Walmer 2 is easier to place; Monitor Audio Silver 500 7G 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 $7,499, about 57% less; arguably a different class. |
A Castle Walmer 2 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 Castle Walmer 2 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 38Hz anyway, so judge these on the other rows instead. If your amplifier is modest, vintage or valve-based, Monitor Audio Silver 500 7G is the safer partner - the other will want more current or more watts to sound its best.
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.
