Fussion Series

Active, High-Output Subwoofer

FUSSION 1800SA/1800S

■

Mackie’s FUSSION 1800SA/1800S is a high-output,

active subwoofer system featuring high-precision 18-inch

transducers combined with application-specific amplifier

technology. The system is composed of two subwoofer cabi-

nets: 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 impreg-

nated 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 tem-

perature rise and substantially improved power compression

characteristics.

■

The Fussion 1800 system amplifier module, located 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 frequency

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 eas-

ily-accessible rear input and control panel offers substantial

signal-routing flexibility. Line-level signal connections are

via XLR connectors. There is a main speaker-level output on

the 1800SA rear panel, which provides signal to the passive

1800S cabinet via an EP-type connector. The system features
