I played a 370 rig for many years and loved it - especially in large venues. Some bandmates complained that the sound on the other side of the stage was muddy so I eventually put a horn on their side which made everyone happy. The folded horn takes quite a distance to achieve its sound, but from there on out it's an amazing cab. The head has a lot of flexibility with the 5 band graphic and always seemed more powerful than it was rated. Eventually I sold the folded horn and got two 1-15" cabs and had a smaller but equally powerful rig. No complaints ever.
After 30+ years I finally had some trouble with the head and while it was being repaired I tried out some modern gear. Wow. We've come a long ways since the good ol' days. The new stuff is much smaller, lighter and just as powerful and there are lots of tonal options from one brand to another. I bought new and sold the old rig. I prefer my sound now and portability is amazing. I'd still like the 370 rig for stadiums but I'm not playing stadiums and P.A. support is everywhere these days. In the old days you had to do it all yourself.
