From the manufacture, the difference between the standard and Anniversary edition is as follows:
1) Additional panels, bolted with a thin layer of constrain mode isolation to the sides and top of the cabinets.
2) Dense and heavy contoured rear panel bolted to the back of the cabinet with isolation layer.
3) Brass Tension rod mechanism across the cabinet walls inside the cabinet against outward movement of the cabinet walls.
4) Better acoustic absorption behind the mechanically grounded main driver.
5) Upgraded internal wiring
6) 6N OFC Silver jumpers
The emphasis is on increased cabinet rigidity much inline with the Reflector.
