Our village hall (about 20m x 6m but very high roof) has what I thought
an adequate PA setup - a Shure hand-held radio microphone feeding a
decent PA amplifier (Carlsboro) feeding four Wharfedale Linton speakers
which are mounted (two on each wall), about 4m up and 5m apart - where
the eaves meet the walls, angled downwards.

The current setup is fine for playing music for kids to dance to. But
some of our older users have complained that speech sounds sound rather
"muffled". I can't sense a real problem myself, but have to admit that
the sound is not as clean as I have heard from good PA systems that use
a pair of speakers at say 2m above the ground. The question is whether
the problem is likely to be the speakers or their position.

It's a fair possibility that the tweeters blew out on the first dance
session, or the first time the mic produced a blast of feedback. Apart
from the question of positioning, domestic hi-fi speakers are not
rugged enough for PA use.
