You can get solid construction for much less, maybe not lumber/timber but Baltic ply, which has performance advantages over plain timber. The wood on Fleetwood's speakers is stabilized by torrefaction, which is an improvement, but at a cost. They are worth more than cheaper-made, including those with Baltic ply, but does that mean $22K a pair? I don't happen to think so, but the marketing at Fleetwood aims at low-volume at a high price with fewer buyers at a tier that isn't shopping for the lowest-priced OMA speaker, which is probably better but of course at a cost of $15-20K over the Fleetwoods.(Monitor and Mini.)
I am happy to see someone making what OMA makes. It is a marker for what is possible if money is not limited, and different from so many other halo product producers at the highest cost tier. I am also happy to see what others with a similar respect for vintage design are doing, Tim Gurney and Vu Hoang with their reinterpretations of Western Electric theater horns. Theirs aren't attainable for most either, but the craft isn't dead because of them and the few like them, and that is reassuring.
