You could probably find a cabinet maker in your area who would cut the pieces for you.
Right now the only flat packs available that I'm aware of for any of Danny's speakers are the ones Jay (Captainhemo) is building for the dual and triple OB subs and the NX-Oticas.
I think jseipp is correct about Danny still having some LGK 1.0 cabinets available. If I remember correctly, they need a little rework though.
