L600 features a 1" Pinnacle Ring Radiator Tweeter, a 5.25" Midrange and 2 x 7" Polypropylene Woofer with a Crossover frequency at 410Hz and 2900Hz. 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
L600 has a frequency range of 34-38k 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 L600's min frequency of 34Hz.
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
L600 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 L600 can provide this impedance level.
These two speakers also have different sensitivity levels. L600 sensitivity is rated at 86 dB and the Silver 500 7G's is rated at 90.5 dB. This 5 dB difference makes the Monitor Audio Silver 500 7G a more sensitive speaker compared to Polk L600, 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.
L600 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 L600.
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 L600 and Silver 500 7G features dual binding post speaker terminals for bi-amping or bi-wiring.
Polk L600's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
L600 has a down firing port whereas Silver 500 7G has a rear firing ports.
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 Polk L600's and Monitor Audio Silver 500 7G's external dimensions. Polk L600 has external dimensions of 1182.0 x 331.0 x 426.0mm (46-1/2 x 13 x 16-3/4inch) 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).
Polk L600 is clearly the larger of the two speakers. Its body is 8mm wider, 97mm taller and 33mm deeper than Monitor Audio Silver 500 7G.
Below you can see the front view size comparison of Polk L600 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 Polk L600 is approximately 1410.1cm2 / 218.6inch2 and base area of the Monitor Audio Silver 500 7G is approximately 1269.4cm2 / 196.8inch2. The L600 requires 11% 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 Polk L600 weighs 35.30kg / 77.7lbs and the Monitor Audio Silver 500 7G weighs 22.53kg / 49.6lbs. This makes the L600 57% heavier than the Silver 500 7G.
Here is a comparison of how L600 and Silver 500 7G'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 | B | Monitor Audio Silver 500 7G digs deeper - 27Hz against 34Hz. A subwoofer would even that out. |
| Amplifier needs | B | Monitor Audio Silver 500 7G is more sensitive (91dB vs 86dB), 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 | evenly matched | Similar power handling (300W vs 250W). |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | Polk L600: bi-amping and Atmos drivers; 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 | evenly matched | Much the same money ($3,498 vs $3,200 a pair). |
A Polk L600 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 has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 34Hz 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.
