An in-wall against a bookshelf. They are built for different places in a room, so start with where these have to go rather than which looks better on paper.
| Area | Better | Why |
|---|
| Bass | B | Monitor Audio Silver 100 7G digs deeper - 35Hz against 40Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (87dB vs 88dB) - both want much the same power. |
| Amplifier match | B | Monitor Audio Silver 100 7G is the easier load at 8 ohms. |
| Type | depends | A Passive In-wall against a Passive Bookshelf - a different job rather than a better one. |
| Expandability | B | Monitor Audio Silver 100 7G: bi-amping. |
| Price | B | Monitor Audio Silver 100 7G is cheaper - $1,400 against $1,998, about 30% less. |
A Monitor Audio W2M B Monitor Audio Silver 100 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 100 7G is the easier recommendation: it leads on most of the measured areas and costs less. Take Monitor Audio W2M 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 40Hz anyway, so judge these on the other rows instead. Think about the whole system, not just the speakers: the roughly $598 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
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.
