Sounds like circa 1990s second generation 10” Walsh drivers mounted on original Walsh 4 cabinets.
Should sound very good if drivers in good shape and driven by a decent power high current amp.
I have Super Walsh 2s which are 3rd generation 8” Walsh drivers on original Walsh 2 cabs and F5s which are 3rd generation 12” Walsh 5 driver with level adjustments mounted on refurbed original Ohm F cabinets since 2008ish and still going strong.
