Have been gifted a pair of Toa Horns. I've no PA experience and looking at current Toa product I assumed these were 70v line drivers...but was told they were used on std home hifi as additional drivers.
Plugged them in to a basic 20watt/ch 3-in-1 home mini system and they seem to play fine. (other than the constrained range of course)
Can anyone explain what may be happening ?

Those are Public Announcement horns not Pro Audio. Horns like this were used in some budget minded PA applications back in the infancy of professional audio development... 50-60yrs ago, so they would be considered a crude blunt instrument these days
These horns also have a long path length which is folded in on itself to physically shorten the assembly. These so called “re-entrant horns” suffer from the same upper frequency limitations of folded horn subwoofers - with the bends causing higher order mode generation. Which just manifests itself as the upper response getting ragged. It’s the price paid for getting the low end down to around 200Hz to support proper vocal reproduction. They don’t make particularly good “midranges” for hi-fi.
