I've just built an 8-channel and a 10-channel system. The speakers
were purchased and the systems use 5.1 and 6.1 amps (2 each) -- total
cost of amplification, under $900 CAN, total power 2,200 watts. These
systems (with small mixers) also have subwoofers, a consideration not
met with most active speaker set-ups.
If the space you are working in is large, there are other
considerations. I recently spent an hour and a quarter listening to
Janet Cardiff's Forty Voice Motet in Toronto (Canada). An
"interesting" idea, in a terrible realization. The average stay of
people who walked into the gallery was 5 - 6 minutes; the piece is
almost twice as long. During this time, only one (other) person
stayed for more than one complete playthrough.
The technical misconceptions and the musical problems were all over
the place. The room was large and quite live. There was no
significant separation of voices unless the listener worked very hard
to do acoustical isolation; the singing was from reasonable to poor.
The musical realization had 2 and 3 (soprano) voices per part,
sometimes singing together and often in tune. When a singer wasn't
singing, the channel was turned off about 2 - 3 seconds after the
part was finished.
My suggestion is that if you know 'next to nothing' about the
technical aspects, that you find someone (or two) who really do(es)
know about these things. There are people around you who have studied
and worked in ea for years and they can bring their sonic, technical
and artistic expertise to your ideas and work.
