Vision Series
High Efficiency Subwoofer Speaker System
PA180SW
SPEAKER
■
The PA180SW high-efficiency subwoofer is the ideal
bass-frequency extension to complement the VISION
series two-way loudspeakers.
■
The low-frequency transducer is a high-power 18"
woofer with a 4" voice coil. Using horn-reflex loading
to the transducer, the subwoofer design ensures an
efficient acoustic response down to 40Hz.
■
The subwoofer system includes a high-level
crossover network that features markedly lower (than
conventional) induction values in series with the
woofer. We call this innovation LICC (Low Impedance
Compensated Crossover). The benefit is delay reduc-
tion, reduced phase shift and superior transient
response. The high-pass crossover section is connect-
ed to terminals on the input plate to facilitate easy
interface with VISION Series two-way loudspeaker sys-
tems. The crossover is easily bypassed for bi-amp or
tri-amp operation via an installer-accessible
changeover block. Back panel indicators display the
current system setting.
■
The Mackie Industrial PA180SW is a part of the
VISION family of loudspeaker products including full-
range, cost-effective, two-way loudspeakers and com-
plementary subwoofer cabinets. The two-way enclo-
sures have a trapezoidal footprint for easy array con-
figuration. All enclosures are constructed using 19mm
void-free, birch plywood and finished with a scratch-
resistant black coating. Transducer components are
protected from the environment by a heavy gauge
metal grille. The VISION products are eminently suited
for fixed installation, ready for suspension via built-in
M10 inserts with metal reinforcement and forged
shoulder eyebolt hardware.
