Horns are all different with differing
lengths and flare-rates, and geometry, so
no fast and easy rule...

Generally, the efficiency gain is about 3X--
maybe more, maybe less. In general, distortion
levels drop as efficiency increases.

Room coverage is bettered by the wider coverage
angles in most cases.

Remember that this all started in movie theatres
where owners liked the idea of covering 1000 people
with 8 watts. As movies got better, the speakers
had to keep pace, so both efficiency and bandwidth
were increased. Distortion levels plummeted as better
drivers and loading schemes continued to advance.

Without movie theatre's insistence on providing a
sense of presence and a sense of realistic dynamics
and voice accuracy, we'd be stuck with panels and
Clock-Radio speakers that can't get it up...

Oh, Wait! Many are using those anyway!
