System Design - Passive/Active
TYPICAL "BI-AMPED" SYSTEM USING
PASSIVE CROSSOVERS
The Cerwin Vega PRO AUDIO COAX HORN
comes with a special 12dB per octave
crossover. It is HIGHLYrecommended that this
be used at ALL times - UNLESS you are using
an active crosssover set at above 7kHz. This
system, shown is "Bi-Amped", but not 'Fully"
active. FRONT channels of this 4 channel
amplifier are driving the mid bass drivers.
REAR channel are driving the tweeters.
The MIDBASS is shown with a 0.1mH inductor
(not included)in series to cross over
the midbass at 6Khz with a 6dB
roll-off. This setup makes it easier
to adjust level of the midbass
versus the tweeter.
(ONLY RIGHT CHANNEL SHOWN)
SYSTEM DESIGN - FULLY ACTIVE
TYPICAL "FULLY ACTIVE" SYSTEM
PH COAX HORN drivers can be "Bi-Amped"
Or what is commonly called FULLY active
system setup. In the system shown - the
tweeter(s) are wired to the FRONT channels
and the MIDBASS driver section is wired to
the rear channels. At this point you should
seriously think about purchasing a DSP
processor - unless your amplifier has a
HP filter that can go to 8Khz Using a
DSP processor makes it much easier
to control and tune your system.
