For the PA cab naturally Sony didn't use expensive SUP drivers.
Instead the company cooperated with McCauley and mounted a modified and rebranded 9620.

This is still an excellent driver, Jean-Michel LeCleac'h liked it a lot.

The same Sony/McCauley drivers were used for Sony's professional cinema loudspeakers. These are extremely rare.

I think most of us have never seen these before, or knew about their existence.

Woofers were also sourced from McCauley, albeit with customized, reinforced chassis.

Those horns are serious bad boys! I have similar double 15's (JBL 4722), but those horns are even bigger than the cabs. Yah, never seen those before, very cool!

In the US, you could buy these DDS horns that look somewhat similar, but are smaller.
The slot length is considerably truncated, which usually is a good thing.
These cost about $250 each.
There's at least 1 member here, that has a number of these in use.

While American brands could build on their legacy without a major impact as a result of World War II, the Japanese had to start all over again.
It is still amazing to see what Japanese audio companies had achieved in the late 1960s and early 1970s.
Of course their crown jewels were not available outside of Japan and for this reason not well known in the rest of the world.

This is a Sony magazine advertisement for drivers from almost 50 years ago.
Both build quality and specifications can stand the comparison with the best drivers of this era.
