A floor-standing 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 | A | Tannoy GRF digs deeper - 24Hz against 40Hz. |
| Amplifier needs | A | Tannoy GRF is more sensitive (95dB vs 86dB), so it goes louder on the same amplifier. |
| Amplifier match | A | Tannoy GRF is the easier load at 8 ohms. |
| Type | depends | A Passive Floor-standing against a Passive Bookshelf - a different job rather than a better one. |
| Price | B | Harbeth SHL5plus XD2 is cheaper - $7,990 against $29,990, about 73% less; arguably a different class. |
A Tannoy GRF B Harbeth SHL5plus XD2
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: Tannoy GRF measures better, Harbeth SHL5plus XD2 costs about about 3.8x the price% 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 40Hz anyway, which makes the cheaper Harbeth SHL5plus XD2 much easier to justify. Match it to your room: we rate Tannoy GRF the better fit for a large room and a very large room, and Harbeth SHL5plus XD2 for a small room and a mid-size room.
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.
