What size room are the Monitor Audio Silver 300 7G and B&W 603 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

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 BW 603 features a 1" Tweeter, a 6" Midrange and 2 x 6.5" Paper Woofer.
Frequency Response
Silver 300 7G has a frequency range of 31-35k Hz whereas BW 603 has a frequency range of 48-28k 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 BW 603's min frequency of 48Hz.
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 and BW 603 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Silver 300 7G sensitivity is rated at 87.5 dB and the BW 603's is at 88.5 dB. This 1 dB difference makes the B&W 603 a more sensitive speaker compared to Monitor Audio Silver 300 7G, 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.
Both handle the same maximum of 200 watts RMS, though Silver 300 7G is rated 80-200 watts and BW 603 30-200 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 BW 603 features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
Both Silver 300 7G and BW 603 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 B&W 603'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 B&W 603 has external dimensions of 985.0 x 190.0 x 340.0mm (38.7 x 7.4 x 13.3inch).
Monitor Audio Silver 300 7G is clearly the larger of the two speakers. Its body is 87mm wider, 51mm taller and 48mm deeper than B&W 603.
Below you can see the front view size comparison of Monitor Audio Silver 300 7G and B&W 603 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 B&W 603 is approximately 646.0cm2 / 100.1inch2. The Silver 300 7G requires 66% more surface area than the BW 603 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 B&W 603 weighs 24.14kg / 53.1lbs. This makes the BW 603 25% heavier than the Silver 300 7G.
Here is a comparison of how Silver 300 7G and BW 603'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 48Hz. |
| Amplifier needs |
evenly matched |
Similar sensitivity (88dB vs 89dB) - both want much the same power. |
| Headroom |
evenly matched |
Similar power handling (200W vs 200W). |
| Size |
depends |
B&W 603 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; B&W 603: bi-amping. Monitor Audio Silver 300 7G sits in a wider range (8 models), so a matched surround system is easier later. |
A Monitor Audio Silver 300 7G
B B&W 603
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 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 48Hz 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, B&W 603 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.
