Siblings in Monitor Audio's Bronze series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass |
A |
Monitor Audio Bronze 100 digs deeper - 37Hz against 50Hz. |
| Amplifier needs |
evenly matched |
Similar sensitivity (87dB vs 88dB) - both want much the same power. |
| Size |
depends |
Similar cabinet size - neither is easier to fit. |
| Type |
depends |
A Passive Bookshelf against a Passive Center Channel - a different job rather than a better one. |
| Cabinet |
depends |
Ported vs Sealed. Sealed is tighter and happier near a wall; ported digs lower but wants space behind it. |
| Expandability |

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 Bronze 100 is the easier recommendation: it leads on most of the measured areas and costs less. Take Monitor Audio Bronze Centre 7G 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 50Hz anyway, so judge these on the other rows instead. Think about the whole system, not just the speakers: the roughly $323 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.
