The AcousticPerformance 
premium, high performance, direct radiating 
dual 12-inch subwoofer designed for use in 
portable and installed sound applications.  
The AP-212sw provides exceptional punch 
while maintaining ample extension so the 
musically important fundamentals are solidly 
and accurately reproduced. With a matching 
profile to the AP-4122m and AP5122m full 
range models, the AP-212sw is an ideal 
companion, providing added low frequency 
extension and musical accuracy to the 
AcousticPerformance portfolio.
The AP-212sw features dual 12-inch woofers 
reversed mounted on a V-baffle for improved 
thermal protection and performance. The 
15mm Baltic Birch enclosure is finished in 
an environmentally friendly, waterborne, 
polymer finish rugged enough for the 
demands of everyday use while also being 
field repairable. Internal bracing is employed 
to eliminate acoustic losses due to panel 
resonance while maintaining the lightweight 
enclosures robustness. Ample port area 
allows free movement of air resulting in 
minimal turbulence and port distortion. 
The versatility of the AP-212sw is evidenced 
by two pole mount options for both vertical 
and horizontal applications. Furthermore, 
when horizontal, the AP-212sw has a 
shallow height, desirable for under riser 
installs. The AP-212sw includes four 
integrated handles and an optional caster  
kit for ease of transport.

The AP-212sw input cup features dual NL4 
connectors in a crossed configuration, where 
pins 2 of the input are returned to pins 1 on 
the thru output. This clever configuration 
allows a single NL4 cable to carry both sub 
and top box signals without the need of a 
custom turn cable. 
Presenting a clean, unobtrusive look, 
AcousticPerformance grilles are unadorned 
eliminating the need to cover-up logo 
treatments which can be difficult to hide 
or remove. The grille is also lined with 
acoustically transparent backing adding to 
the enclosure’s professional appearance. 
The AP-212sw is available in black (RAL 
9011) finish. 
To further enhance performance and speed 
of install with optimum result, proprietary 
Intrinsic Correction™ tunings are obtainable 
via Q-Sys networked audio processing 
platforms, including CXD and PLD amplifiers 
for a complete QSC systems solution.
