At one point I had small format drivers and horns spanning several eras - multiple examples of 802/806/902/811/511.

In the end I guess I liked the 802D/511 best - it was the last and longest lasting configuration - the 511 was late-production with the vanes parted at the center - not welded - and filled with a silicone-like damping compound. This was pure factory - not an aftermarket modification.

But I also hasten to add that imagination could play as big a role as reality.
