Siblings in Monitor Audio's Bronze series, so they share a family sound. It comes down to size, output and price.

Which should you choose?
The usual trade-off: Monitor Audio Bronze 300 7G measures better, Monitor Audio Bronze AMS 7G costs about 38% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 83Hz anyway, which makes the cheaper Monitor Audio Bronze AMS 7G much easier to justify. If your amplifier is modest, vintage or valve-based, Monitor Audio Bronze 300 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.
