Silver 300 7G features a 1" gold dome C-CAM with Uniform Dispersion (UD) Waveguide II Tweeter, a 3" Midrange and 2 x 6" C-CAM RST II Woofer. On the other hand, the Opticon 6 MK2 features a 17 x 45 mm ribbon + 1.125" Soft-dome + ribbon Hybrid Tweeter and 2 x 6.5" Wood Fiber Woofer with a Crossover frequency at 800Hz, 2200Hz and 14,000Hz.
Frequency Response
Silver 300 7G has a frequency range of 31-35k Hz whereas Opticon 6 MK2 has a frequency range of 49-30k Hz. With a minimum frequency of 31Hz, the Silver 300 7G can go significantly deeper on the low side and provide stronger bass compared to the Opticon 6 MK2's min frequency of 49Hz.
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
Silver 300 7G is a 8 ohms speaker compared to the Opticon 6 MK2 which has a nominal impedance of 4 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 Opticon 6 MK2 can provide this impedance level.
These two speakers also have different sensitivity levels. Silver 300 7G sensitivity is rated at 87.5 dB and the Opticon 6 MK2's is rated at 88 dB.
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.
Both handle the same maximum of 200 watts RMS, though Silver 300 7G is rated 80-200 watts and Opticon 6 MK2 25-200 watts.
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.

Input Type and Bi-Amping / Bi-Wiring
Both Silver 300 7G and Opticon 6 MK2 features dual binding post speaker terminals for bi-amping or bi-wiring.
DALI Opticon 6 II's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Silver 300 7G and Opticon 6 MK2 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 Monitor Audio Silver 300 7G's and DALI Opticon 6 II's external dimensions. Monitor Audio Silver 300 7G has external dimensions of 1036.0 x 277.0 x 388.0mm (40-3/4 x 10-7/8 x 15-1/4inch) whereas DALI Opticon 6 II has external dimensions of 1010.0 x 195.0 x 340.0mm (39-3/4 x 7-5/8 x 13-3/8inch).
Monitor Audio Silver 300 7G is clearly the larger of the two speakers. Its body is 82mm wider, 26mm taller and 48mm deeper than DALI Opticon 6 II.
Below you can see the front view size comparison of Monitor Audio Silver 300 7G and DALI Opticon 6 II 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 300 7G is approximately 1074.8cm2 / 166.6inch2 and base area of the DALI Opticon 6 II is approximately 663.0cm2 / 102.8inch2. The Silver 300 7G requires 62% more surface area than the Opticon 6 MK2 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 300 7G weighs 19.32kg / 42.5lbs and the DALI Opticon 6 II weighs 19.30kg / 42.5lbs. This makes the Silver 300 7G 0% heavier than the Opticon 6 MK2.
Here is a comparison of how Silver 300 7G and Opticon 6 MK2'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 | A | Monitor Audio Silver 300 7G digs deeper - 31Hz against 49Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (88dB vs 88dB) - both want much the same power. |
| Amplifier match | A | Monitor Audio Silver 300 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 (200W vs 200W). |
| Size | depends | DALI Opticon 6 II is easier to place; Monitor Audio Silver 300 7G is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Monitor Audio Silver 300 7G: bi-amping; DALI Opticon 6 II: bi-amping. |
| Price | evenly matched | Much the same money ($2,600 vs $2,500 a pair). |
A Monitor Audio Silver 300 7G B DALI Opticon 6 II
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 300 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 49Hz anyway, so judge these on the other rows instead. In a large or open-plan room, Monitor Audio Silver 300 7G has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, DALI Opticon 6 II is the easier speaker to get right.
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.
