FUSSION 1800SA/1800S

■ Mackie's FUSSION 1800SA/1800S is a high-out-

put, active subwoofer system featuring high-precision
18-inch transducers combined with application-spe­cific amplifier technology. The system is composed of
two subwoofer cabinets: the 1800SA, which contains
a single 18-inch woofer and the active electronics,
and the 1800S, a single 18-inch woofer cabinet that
functions as a slave.

■ Transducers used in the FUSSION 1800SA/1800S

system feature 4-inch, Inside/Outside-wound voice
coils that offer extreme power-handling capabilities.
The cone assembly is reinforced with long-strand car­bon fiber, which is impregnated into the cone.
Extensive materials science research and develop­ment has led to significant advancements in adhe­sives, voice coil former materials, surround and spi­der technologies. FUSSION 1800SA/1800S transduc­ers were specifically designed for use in this type of
enclosure design. The magnetic assemblies used
incorporate advancements in coil venting and struc­tural cooling that provide lower temperature rise and
substantially improved power compression character­istics.

■ The Fussion 1800 system amplifier module, locat-

ed in the 1800SA cabinet, is an excellent example of
the efficiency that is possible with active designs.
This module uses two high-efficiency, high-current,
CLASS G topology amplifiers running in bridged mode
to produce 2500 watts of power. Instead of an
onboard control system, the system relies on external
processing supplied by any FUSSION full range or
mid-high speaker system or by a stand-alone proces­sor.

■ FUSSION 1800SA/1800S subwoofer system fre-

quency response is linear between 38Hz and 150Hz.
When used with any FUSSION full range or mid-high
speaker system, the onboard processor provides com­plete system management of all electronic and
acoustic functions including electronic active
crossover, electronic phase alignment, electronic time
correction, electronic equalization and complete
amplifier and component protection.

■ To ensure long-term reliability and performance,

the amplifier cards and processor are mounted to a

huge heat sink eliminating the need for fans, dra­matically extending life expectancy and eliminat­ing maintenance cycles. An easily-accessible rear
input and control panel offers substantial signal­routing flexibility. Line-level signal connections
are via XLR connectors. There is a main speaker­level output on the 1800SA rear panel, which pro­vides signal to the passive 1800S cabinet via an
EP-type connector. The system features soft-start
circuitry that eliminates pops and precisely con­trols AC inrush current surges.

■ Fussion 1800S and 1800SA cabinets are con-

structed using 18mm thick multi-layered birch
plywood and finished in black splatter paint.
There are two handles on each side for efficient
loading and transport.
