The midbass drivers (Vifa TC14WG49-08 or TC14SG49-08) for the Linus II may still be available but are no longer currently produced. But they are shown in the Madisound on-line catalog. The tweeter is the Silver Flute YAG20 which is also available from Madisound.

I can not recommend any alternative drivers other than these.

I'll send you the plans later today.
