£50k that’s PMC/ATC pricing but with hugely better performance.Those without the dosh could consider the still impressive JBL 4367 with 15" bass to upper mid driver and say, a Benchmark amp to drive them, total cost well under twenty grand in pounds or dollars I think.
I got the possible size wrong, so maybe the same as regards costs, but would these new models really be north of fifty grand the pair? Truth will out I'm sure and good luck to the company!
