There is no publicly documented "updated" or superseding modern B&W driver that officially replaces the LF00215 in service documentation for this model.
If you need to replace it use the same LF00215 as an exact replacement.
I’d try one of the options below. All 8 ohm. Historically the HTM4 and 805 are the same but different form factor despite the different part number.
They look like a straight fit, except maybe the D2 with a little chiseling. The newer models should have a lower extension. Worst case, resell it.
