Siblings in GoldenEar's Triton series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
| Bass |
A |
GoldenEar Triton Five digs deeper - 26Hz against 29Hz. A subwoofer would even that out. |
| Amplifier needs |
evenly matched |
Similar sensitivity (90dB vs 91dB) - both want much the same power. |
| Amplifier match |
A |

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?
GoldenEar Triton Five has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If your amplifier is modest, vintage or valve-based, GoldenEar Triton Five 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.
