Siblings in Revel's Architectural series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Amplifier needs | evenly matched | Similar sensitivity (89dB vs 89dB) - both want much the same power. |
| Amplifier match | A | Revel W763 is the easier load at 8 ohms. |
| Size | depends | Revel W763 is easier to place; Revel W126Be is bigger, which usually goes with fuller bass. Your room decides. |
| Price | A | Revel W763 is cheaper - $1,210 against $3,850, about 69% less; arguably a different class. |
A Revel W763 B Revel W126Be
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?
Revel W763 has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. In a large or open-plan room, Revel W126Be has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Revel W763 is the easier speaker to get right. Think about the whole system, not just the speakers: the roughly $2,640 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.
