A7's were the speakers to have at one time for their efficency. They
had no true bottom end (woofer horn was designed for low-mids), no highs
(no tweeters), but they could play very loud. That is what they were
designed to do. A band I was in had clones of them made out of
particle. They sounded good as far as a bar goes, but they were heavy
to move. If you didn't have a bank of Crown DC-300's to work with, the
A7 was a great alternative to get volume.

Klipsh Lascala's were up there for sound also, and they used EV T35
tweeters back mouted which limited the dispersion for the tweeters.

JBL, which wasn't even mentioned, is used alot.

To the originator of this post, all they were wanting was a way to
protect the investment. Saying an A7 won't do what he is wanting is not
the truth. They will play loud music for a bunch of tipsy listeners who
couldn't tell freq response if they had too.

( Been there, done that, got paid - lol)

They will be heavy to move and care must be given them so as to not be
dropped, but they will get the gig done.

The addition of subs and tweeters would help their overall sound though.
