Designing an active loudspeaker system
is a complex (but fascinating)
matter because each drive unit needs
its own output amplifier and cross-over
filter. But, of course, an active system has
several advantages. Over a passive one.
The present circuit, comprtsmg three
ülter seetions, active bass corrective network,
and three output stages, fits on just
one pIinted-circuit board.
