Easy to replicate? Yes, I still have the DXF files for it, and the BDF for the machine, now they are indeed very costly, I did them more as a project, and to test my capabilities in programming the CNC. As an employee with a very special price, I ended paying around $150.00 for them both, these are made out of 1/2 clear annealed glass, done on an Italian Bimatech CNC machine, routed out, and Pencil Polished, and with 8 drilled holes in each..Spikes were an additional $20.00 a set from Part Express, plus some other stand-off hardware to use the covers, and two sets of Axiom rubber legs on each speaker...
