Siblings in DALI's Phantom series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | B | DALI Phantom H 80 digs deeper - 46Hz against 52Hz. A subwoofer would even that out. |
| Amplifier needs | B | DALI Phantom H 80 is more sensitive (90dB vs 88dB), so it goes louder on the same amplifier. |
| Size | depends | DALI Phantom H-50 is easier to place; DALI Phantom H 80 is bigger, which usually goes with fuller bass. Your room decides. |
| Price | A | DALI Phantom H-50 is cheaper - $798 against $1,000, about 20% less. |

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?
The usual trade-off: DALI Phantom H 80 measures better, DALI Phantom H-50 costs about about 25% more% 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 52Hz anyway, which makes the cheaper DALI Phantom H-50 much easier to justify. In a large or open-plan room, DALI Phantom H 80 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, DALI Phantom H-50 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.
