The ACE 500 product line consists of three

models: the ACE 540, ACE 550, and the ACE 570.
The ACE 540 delivers excellent performance from
a two-way, infinite baffle enclosure. The ACE 550
and ACE 570 are two-way, ported enclosures that
boast extended low frequency response. All three
models make use of a 1" dome tweeter for the HF
transducer. The ACE 540 and ACE 550 use a 5.25"
LF transducer while the ACE 570 uses a 7" LF
transducer. All models are housed in a trapezoidal-
shaped enclosure—making these speakers well
suited for numerous audio environments.

All 500 Series loudspeakers employ a passive

crossover and have a nominal coverage pattern of
120°. Neutrik

®

NL4 Speak-On connectors, binding

posts, and mounting points are included.

QSC-ACE enclosures incorporate Composilite™,

a patented core composite technology that yields
superior acoustic properties, lighter weight, and
outstanding weather resistance compared to
conventional enclosure materials. Multiple skins
of carbon fiber are layered over a phenolic honeycomb
core to form a rigid, seamless enclosure. The
extreme stiffness of composite construction prevents
flexing of the enclosure walls, significantly
reducing transmission loss due to wall vibration. The
result is reduced cabinet resonance, increased
low-frequency output, and greater sonic accuracy.
A comprehensive line of mounting accessories
and optional color choices make the QSC-ACE
500 Series a versatile solution.
